How to Fix E1/E2 Error Codes on your Dryer

The E1 or E2 Error Code can display on many dryer brands, including Whirlpool, LG, Maytag, and Samsung. If the heated air is not at the ideal temperature, the faulty device may send this error code eventually.

E1 Error Code: Usually indicates an open thermistor or a disconnected wire.

E2 Error Code: It usually indicates a shorted thermistor that makes the dryer misread the temperature.

If your dryer shows these codes, it may no longer heat up, overheat, or stop working entirely.

E1/E2 Error Codes: How to Troubleshoot

Reset Your Dryer

And before delving into more complicated fixes, you can give a simple reset a try:

✔ Turn off power to the dryer.

✔ Wait for 5-10 minutes until the internal components reset.

✔ Replug the dryer and resume the cycle.

If the error is not resolved, continue with the following steps:

Inspect the Dryer’s Ventilation System

Temperature readings can also be inaccurate owing to poor air flow.

✔ Clear the lint filter and clean it.

✔ Check the exhaust vent for blockages and clean away any lint buildup.

✔ Make sure the dryer vent hose isn’t kinked or restricted.

Clogging of your ventilation can cause overheating and E1/E2 error codes.

Test the Thermistor

The thermistor is a resistor that is temperature-sensitive and regulates heat. To check if it’s working:

✔ Disconnect the dryer from power and find the thermistor (usually located in the vicinity of the blower housing).

✔ Measure resistance at room temperature with a multimeter (about 10k ohms).

✔ If resistance is too high or low, the thermistor is defective and must be replaced.

Check the Wiring and Connections

✔ Remove the back panel of the dryer and inspect the thermistor wiring harness.

✔ Check for loose, damaged or disconnected wires and secure.

✔ If wires look burned or broken, you might need to replace them.

How to Fix E1/E2 Error Codes

If troubleshooting indicates that the thermistor has indeed failed, replace it as follows:

Buy a Compatible Thermistor

All of this should be done with care, and make sure you purchase a thermistor that is manufacturer-approved for your model of dryer. You can get replacement parts at appliance repair stores or online.

Disconnect the Power

Safety first! Note: Always disconnect the dryer or turn off the circuit breaker before working on electrical components.

Access the Thermistor

✔ If your dryer has a back panel (or a lower front panel), remove it.

✔ PINPOINT THE THERMISTORS LOCATED NEAR THE BLOWER HOUSING

Remove the Faulty Thermistor

✔ Unplug the wiring harness from the thermistor.

✔ Unscrew the thermistor and gently pull.

Install the New Thermistor

• Place screws to secure the new thermistor.

✔ Reattach the wiring harness, if equipped.

Reassemble and Test

✔Reinsert the dryer panels.

✔ Reconnect the power and run a wash cycle to verify that E1/E2 error code has been cleared.
