Whirlpool Dryer Error Codes

Whirlpool dryers use a straightforward error code system that helps pinpoint exactly where problems occur. The codes display on the digital control panel as either two-character codes or alphanumeric combinations starting with F followed by E.

Whirlpool and Maytag share the same error code system since both brands fall under the Whirlpool Corporation umbrella. If you own a Maytag dryer, the codes in this section apply to your machine as well.

AF or F4E3 – Restricted Airflow

The AF code means your dryer has detected significantly restricted airflow. This happens when lint buildup blocks the exhaust vent or when the vent hose becomes kinked. Your dryer will still run but will take much longer to dry clothes.

Start by removing and thoroughly cleaning the lint screen. Then disconnect the vent hose from the back of the dryer and check for blockages. Run the dryer on air fluff for a few minutes to clear any loose debris. If the code persists, you may need to clean the entire vent duct running to the outside of your home.

F# E# – Component Failure

When you see any code starting with F followed by E and numbers, your dryer has detected a failure in a specific component. Common examples include F01 E01 for a primary control failure or F22 E01 for a exhaust thermistor problem.

These codes typically require professional diagnosis and repair. You can try unplugging the dryer for five minutes to reset the control board, but if the code returns, call a qualified technician. Attempting to repair these components yourself without proper training can void warranties and create safety hazards.

L2 – Low Line Voltage

The L2 code indicates your dryer is not receiving adequate voltage. Dryers require 240 volts to operate properly. This code appears when voltage drops below acceptable levels.

Check your home’s electrical panel for tripped breakers. A dryer needs two breakers connected together, and if one trips, voltage drops. If breakers appear fine, the problem could be loose wiring connections or issues with your home’s electrical supply. Contact an electrician if you are not comfortable checking electrical connections.

PF – Power Failure

PF simply means the dryer lost power during a cycle. This could result from a power outage, a tripped breaker, or someone unplugging the machine.

Press the Start button to resume the cycle, or press Power/Cancel to clear the display. This code does not indicate any problem with your dryer and requires no repair action.

F01 – Primary Control Failure

The F01 error indicates a complete failure of the main electronic control board. This often happens after power surges or when the board reaches end of life.

Unplug the dryer for several minutes to attempt a hard reset. If the code returns when you plug it back in, you will need to replace the control board. This repair typically costs between 200 and 400 dollars depending on your model.

F22 and F23 – Thermistor Errors

These codes indicate problems with the exhaust thermistor, which measures the temperature of air leaving your dryer. The F22 code means the thermistor has short-circuited, while F23 means it has an open circuit.

First unplug the dryer and check the wiring connections to the thermistor. The thermistor sits near the blower housing. If wires look secure, you may need to replace the thermistor component, which typically costs 15 to 30 dollars and can be a DIY repair for handy homeowners.

F26 – Motor Drive System Failure

The F26 code indicates the control board cannot communicate with the motor properly. This can stem from motor failure, wiring issues, or control board problems.

Listen when you try to start the dryer. If you hear humming but no rotation, the motor may have failed. If you hear nothing, the problem likely lies with the control board. This repair usually requires professional service.

F28 and F29 – Moisture Sensor Errors

These codes relate to the moisture sensor strips inside your dryer drum. F28 indicates a shorted moisture sensor, while F29 indicates an open circuit.

Clean the sensor bars with a soft cloth and mild detergent. These metal strips located near the lint filter detect when clothes are dry. If cleaning does not resolve the code, the sensor wiring may need replacement.

F30 and F31 – Restricted Airflow

Similar to the AF code, these indicate airflow problems detected by the control system. F30 appears when the dryer detects a 30% reduction in airflow, while F31 indicates a 31% reduction.

Follow the same troubleshooting steps as for the AF code. Clean every component of the airflow path from the lint screen through the vent duct to the outside termination.

F70 and F71 – Communication Errors

These codes indicate communication failures between different electronic boards in your dryer. F70 means the main control cannot communicate with the user interface board, while F71 indicates the opposite.

Check the ribbon cable connections between the boards. Unplug and reconnect them firmly. If this does not resolve the issue, one of the boards may need replacement.

LG Dryer Error Codes

LG dryers use a unique alphanumeric system where letters indicate the type of problem and numbers provide additional detail. The d-series codes relate to vent blockage, while tE codes indicate thermistor issues.

d75, d80, d90, d95 – Vent Blockage Detection

These codes represent the most common LG dryer errors. The number indicates the percentage of exhaust blockage detected. D75 means 75% blocked, d80 means 80% blocked, and so on.

Many users report frustration because these codes sometimes persist even after cleaning vents. The issue often lies in the sensor itself or in hidden blockages within the ductwork. I have seen cases where a single sock lodged in the vent caused these codes to appear.

First, clean the lint filter thoroughly and vacuum out the filter housing. Then disconnect and inspect the vent hose. Check the exterior vent cap for bird nests or debris. Run a vent brush through the entire duct. If the code continues, the blockage sensor may need cleaning or replacement.

tE1, tE2, tE3, tE4 – Thermistor Errors

LG dryers have multiple thermistors that monitor temperatures at different points. The tE1 code indicates the dryer’s main thermistor has failed. TE2 relates to the steam generator thermistor in models with steam features. TE3 and TE4 indicate problems with inlet and outlet thermistors.

These sensors cost 10 to 25 dollars and sit at various points in the airflow path. Check wiring connections first. If wires look good, replacing the specific thermistor usually resolves the code. Always unplug the dryer before working on internal components.

PS – Power Supply Error

The PS code appears when the dryer detects improper voltage. LG dryers need stable 240-volt power.

Check your circuit breaker panel and ensure both dryer breakers are properly engaged. Test the outlet with a multimeter if you have one. Voltage fluctuations in your home can also trigger this code.

CL – Control Lock

CL does not indicate an error. It means the control lock feature is active, preventing accidental button presses.

Press and hold the Child Lock or Control Lock button for three seconds to deactivate. The exact button varies by model but usually displays a lock symbol.

nP – No Power

The nP code indicates the dryer cannot detect proper electrical power. Check your power cord connections and ensure the outlet provides 240 volts.

Some users report this code appearing intermittently when using extension cords or power strips, which you should never use with dryers.

SS – Steam System Error

On dryers with steam functions, SS indicates a problem with the steam generator. Check that the water supply valve is fully open and the inlet hose is not kinked.

If water supply looks good, the steam generator itself may have failed. This component typically requires professional replacement.

HS – Home Safety Error

The HS code appears when the dryer detects temperatures exceeding safe limits. This safety feature prevents fires.

Immediately stop using the dryer and check for severe vent blockages. If vents are clear, the heating element may be stuck on, requiring professional service.

Samsung Dryer Error Codes

Samsung uses a comprehensive two-character code system that covers everything from power issues to component failures. Their error codes are among the most detailed in the industry.

9C1, 9E, 2E – Voltage Errors

These codes indicate power supply problems. The 9C1 code means the frequency of your electrical supply is outside normal parameters. The 9E code indicates the dryer cannot detect proper voltage. The 2E code means the internal voltage sensor has failed.

First, check your home’s electrical supply at the breaker panel. If you recently experienced a power outage or brownout, these codes may appear temporarily. Unplug the dryer for five minutes to reset. If codes persist, contact an electrician to check your home’s wiring.

bE, bE2 – Button Errors

These codes indicate stuck buttons on your control panel. BE means one button is stuck, while bE2 indicates multiple stuck buttons.

Inspect the control panel for damage or debris. Clean around buttons with a slightly damp cloth. If buttons appear damaged or the code persists, the control panel assembly may need replacement.

dC, dE – Door Errors

The dC code means the door is open when the dryer tries to start. The dE code indicates the door switch has failed.

Check that the door latch engages properly when closed. Listen for the click of the door switch. If the door seems closed but the code appears, the door switch assembly likely needs replacement. This is a 20 to 40 dollar part that many homeowners can replace themselves.

tS, t5, tC – Temperature Sensor Errors

These codes relate to the temperature monitoring system. TS indicates the temperature sensor has short-circuited. T5 means the sensor has an open circuit. TC means the dryer cannot properly control temperature.

Check the sensor located near the heating element. Ensure wires are securely connected. Replace the sensor if wiring looks good.

HC, hE – Heating Errors

HC indicates the dryer is getting too hot, usually due to vent blockage. HE means the heating element has failed or cannot activate.

For HC, clean all vents immediately. For hE, check the heating element for visible damage. The heating element costs 50 to 100 dollars and replacement is a moderately difficult DIY repair.

AC, Et – Communication Errors

AC means a communication error occurred between components. Et indicates a control board communication failure.

These codes often require professional diagnosis. Try unplugging the dryer for several minutes to reset all boards. If the code returns, a technician should examine the wiring harness and control boards.

FC, FE – Frequency Errors

FC means the power supply frequency is too low. FE means the frequency is too high. In North America, dryers expect 60 Hz power.

These codes typically indicate problems with your home’s electrical supply rather than the dryer itself. Contact your utility company or an electrician.

Clg, C80, C90, C91 – Vent Blockage Test Results

These codes appear after running Samsung’s vent blockage test. CLG indicates a clogged vent. C80 means 80% blockage, C90 means 90% blockage, and C91 means 91% blockage.

Clean the entire vent system thoroughly. Samsung’s sensors are particularly sensitive to airflow restrictions. Even a partially blocked vent can trigger these codes.

dn – Download in Progress

The dn code appears on smart dryers when firmware updates download. This is normal and not an error.

Allow the download to complete. Do not unplug the dryer during this process.

Maytag Dryer Error Codes

Since Maytag operates under Whirlpool Corporation ownership, their dryers use identical error codes to Whirlpool models. Refer to the Whirlpool section above for complete code explanations.

The most common Maytag codes include AF for airflow restriction, F# E# for component failures, L2 for low voltage, and PF for power failure. Centennial and Bravos models use this same coding system.

Maytag dryers occasionally display the EN code, which indicates an error that does not match any standard code in the system’s memory. This usually requires a service call for proper diagnosis.

Kenmore Dryer Error Codes

Kenmore dryers are manufactured by various companies including Whirlpool, LG, and Frigidaire. The error codes depend on who built your specific model. Check your dryer manual or look at the model number tag to determine the manufacturer.

For Whirlpool-built Kenmore models, use the Whirlpool error codes above. For LG-built models, use the LG codes. The following codes apply to many Kenmore models regardless of manufacturer.

E1 and E2 – Thermistor Errors

These codes indicate the thermistor has failed or reads out of range. E1 typically means the thermistor circuit is open, while E2 means it is shorted.

Locate the thermistor near the blower housing or heating element. Check wiring connections first. Replacement thermistors cost 15 to 30 dollars.

F1 and F2 – Control Board Errors

F1 indicates a primary control board failure. F2 indicates a user interface board failure.

Try resetting the dryer by unplugging it for five minutes. If codes return, professional service is needed. Control board replacements cost 150 to 300 dollars.

F3 – Ignition Error (Gas Models)

On gas dryers, F3 means the igniter failed to light the gas burner. Check that the gas supply valve is open. Listen for the clicking of the igniter when starting a cycle.

If you hear clicking but no ignition, the gas valve solenoids may have failed. This repair costs 30 to 50 dollars for parts.

F4 – Flame Sensor Error (Gas Models)

The F4 code means the flame sensor cannot detect the burner flame properly. Clean the sensor rod near the burner assembly. If cleaning does not help, replace the flame sensor.

AF – Airflow Restriction

Like Whirlpool and Maytag models, the AF code indicates restricted airflow. Clean all vents and the lint screen thoroughly.

GE Dryer Error Codes

GE dryers use a numeric E-series code system. The E1 and E2 codes are most common and relate to thermistor problems. Higher E-codes indicate control board issues.

E1 – Thermistor Circuit Open

The E1 code indicates the dryer’s thermistor has an open circuit and cannot read temperatures. The dryer may overheat or fail to heat properly.

Check wiring to the thermistor first. If connections look good, replace the thermistor located near the heating element housing.

E2 – Thermistor Circuit Shorted

E2 means the thermistor circuit has shorted. The dryer will shut down as a safety precaution.

Unplug the dryer and check the thermistor wiring for damage. Replace the thermistor if wiring looks intact.

E3 through E9 – Control Board Errors

These higher E-codes indicate various control board and communication problems. E3 typically means the control board has failed. E4 through E9 indicate specific component communication failures.

Try resetting the dryer by unplugging it for several minutes. If codes persist, professional service is required. Control board replacements typically cost 200 to 400 dollars.

HTR – Heater Error

The HTR code indicates a problem with the heating element or its control circuit. The element may have broken, or the relay controlling it may have failed.

Check the heating element for visible breaks or damage. You can test the element with a multimeter for continuity. Replacement elements cost 50 to 100 dollars.

In and Out – Inlet and Outlet Temperature Errors

Some GE models display In or Out codes when inlet or outlet thermistors fail. These work similarly to the E1 and E2 codes but specify which thermistor has the problem.

Check the specific thermistor indicated by the code and its wiring connections.

How to Troubleshoot Dryer Error Codes by Symptom

Sometimes your dryer shows symptoms without displaying a clear code. Understanding which components cause common problems helps you diagnose issues even without error messages.

Vent and Airflow Problems

Airflow issues cause the majority of dryer problems and trigger many error codes. When airflow becomes restricted, temperatures rise and sensors shut down the machine for safety.

Start troubleshooting by removing and cleaning the lint filter. Then disconnect the vent hose from the dryer and look inside for blockages. Check the exterior vent cap for debris or animal nests. A vent cleaning brush kit costs 20 to 30 dollars and pays for itself by preventing future problems.

If you have a long vent run with multiple bends, consider having the duct professionally cleaned every two years. Homes with pets may need more frequent cleaning due to hair accumulation.

Heating Problems

When your dryer runs but clothes stay cold, the heating element, thermal fuse, or thermistor likely has failed. The thermal fuse is a safety device that blows when temperatures get too high.

Check the thermal fuse first using a multimeter. This 10-dollar part is easy to replace. If the fuse tests good, examine the heating element for breaks. The thermistor should also be tested for proper resistance values at room temperature.

Door and Sensor Issues

If your dryer will not start, check the door switch. This simple switch tells the control board that the door is securely closed. You should hear a click when pressing and releasing the door latch.

Moisture sensor bars can become coated with fabric softener residue, causing them to misread. Clean them with rubbing alcohol and a soft cloth.

Power and Control Problems

Many mysterious dryer problems stem from power issues. Check that your dryer outlet provides 240 volts using a multimeter. If voltage drops, the dryer may run but perform poorly.

After power outages, dryers sometimes need a hard reset. Unplug the machine for five minutes to clear any scrambled control board memory.

DIY Fixes vs Professional Repair

Knowing when to attempt repairs yourself and when to call a professional saves money and keeps you safe. Some dryer repairs are simple and low-risk, while others require specialized knowledge.

Safe DIY Repairs

You can safely handle several common dryer problems yourself. Cleaning vents and lint screens requires no tools beyond a vacuum and brush. Replacing the lint filter, door switch, and thermistor are straightforward repairs most homeowners can complete in under an hour.

Heating element replacement is moderately difficult but doable for handy homeowners. Always unplug the dryer before working on it. Wear safety glasses when working inside the dryer cabinet.

Replacement parts are available from appliance parts stores and online retailers. Always have your model number ready when ordering parts to ensure compatibility.

When to Call a Professional

Call a qualified technician for any repair involving gas lines, control boards, or complex wiring. Gas dryer repairs present fire and explosion risks if done incorrectly. Control board problems often require diagnostic equipment to identify properly.

Any error code that returns after you attempt a reset indicates a component failure needing professional attention. Do not continue using a dryer that displays error codes related to overheating or safety systems.

Expect to pay 75 to 150 dollars for a service call plus parts. Major repairs like control board replacement can cost 300 to 500 dollars total. Compare repair costs to the price of a new dryer, which typically ranges from 400 to 1200 dollars depending on features.

Cost Considerations

A good rule of thumb is to replace your dryer if repairs exceed 50% of a new machine’s cost. If your dryer is over ten years old, replacement often makes more financial sense than major repairs.

Newer dryers offer energy savings that can offset replacement costs over time. Look for Energy Star certified models when shopping for replacements.

Prevention and Maintenance Tips

Regular maintenance prevents most dryer error codes and extends your appliance’s life. A few simple habits keep your dryer running smoothly for years.

Clean the Lint Filter After Every Load

This simple habit prevents the majority of airflow problems. Remove the lint screen and peel off accumulated lint before starting each new load. Once a month, wash the screen with warm soapy water to remove invisible fabric softener buildup.

Schedule Vent Cleaning Annually

Mark your calendar to clean the entire vent system once per year. Disconnect the vent hose from the dryer and vacuum out accumulated lint. Run a vent brush through the exterior duct to clear any blockages.

Watch for warning signs that your vents need cleaning. If clothes take longer to dry than they used to, or if the dryer exterior feels unusually hot, check your vents immediately.

Inspect the Exterior Vent Cap

Check the outside vent termination quarterly. Ensure the flap opens freely when the dryer runs and closes completely when off. Remove any debris, leaves, or bird nests blocking the opening.

Leave Space Around the Dryer

Your dryer needs airflow around it to function properly. Maintain at least six inches of clearance between the dryer and walls. Do not stack items on top of the dryer that could block ventilation.

Use the Right Settings

Overloading your dryer strains the motor and extends drying times. Follow manufacturer recommendations for load sizes. Use sensor dry cycles rather than timed dry when possible, as sensors prevent over-drying that wastes energy.

Annual Professional Inspection

Consider having a technician inspect your dryer annually, especially for gas models. They can check gas connections, internal components, and vent systems with specialized equipment.
