The E2 error code on a Whirlpool Duet dryer indicates that the thermistor has shorted. This guide will walk you through the steps necessary to troubleshoot and repair this issue, ensuring your dryer returns to normal operation. Follow these detailed instructions carefully to diagnose and fix the E2 error code.

Step 1: Safety First

Before starting any repair work, ensure your safety by turning off the gas to the dryer (if applicable) and disconnecting the electrical power. This will prevent any accidental electrical shocks or injuries while you work on the appliance.

Step 2: Access the Thermistor

To access the thermistor, follow these steps:

1. Open the dryer door and remove the lint filter screen, then close the door.

1. Locate the toe panel at the bottom of the dryer. Remove the two hex-head screws from the bottom flange of the toe panel. Pull the panel out at the bottom, pull down, and remove the panel.

1. Next, remove the hex-head screws from the lint duct bracket, remove the clip and pull out the lint duct.

Step 3: Inspect and Test the Thermistor

With the thermistor now accessible, it's time to inspect and test it:

1. Locate the thermistor, which is attached to the dryer’s exhaust housing.

1. Carefully disconnect the two wires from the thermistor terminals.
2. Remove the two hex-head screws securing the thermistor, and then remove the thermistor from the dryer.
3. Use a multimeter to test the thermistor’s resistance. Refer to the following resistance chart to determine if the thermistor is functioning properly:

Step 4: Analyze the Test Results

Compare the resistance readings from your multimeter to the values in the chart above. If the readings are significantly different from the values listed, the thermistor is likely faulty and needs to be replaced. If the readings are correct, the thermistor is functioning properly, and you may need to look for other issues such as a problem with the wiring or the control board.

Step 5: Check the Wiring and Control Board

If the thermistor test shows it is functioning properly, inspect the wiring leading to the thermistor and the control board. Look for any visible damage, such as frayed wires or loose connections, and repair or replace them as needed. Use your multimeter to test for continuity in the wires to ensure they are not broken or damaged internally.

Step 6: Replace the Thermistor (if necessary)

If you have determined that the thermistor is faulty, replace it with a new one:

1. Align the new thermistor with the mounting holes and secure it with the two hex-head screws.
2. Reconnect the two wires to the thermistor terminals, ensuring they are securely attached.
3. Reassemble the lint duct, lint duct bracket, and toe panel by reversing the steps you took to remove them.

Step 7: Test the Dryer

After completing the repair, it's time to test your dryer to ensure the problem is resolved:

1. Reconnect the dryer to its power source and, if applicable, turn the gas back on.
2. Select a drying cycle and start the dryer. Observe its operation for several minutes to ensure it heats up correctly and operates without displaying the E2 error code.

If the dryer operates normally without the E2 error code appearing, you have successfully repaired the issue. If the error code reappears, there may be another underlying issue that needs to be addressed. If you determine that the control board is at fault and need to know which control board is compatible with your dryer model, please submit a question to our Ask a Question page, and we will be glad to assist you.
