How to Check If a Whirlpool Electric Dryer's Door Switch is Faulty

If your Whirlpool electric dryer is not turning off when the door is opened or if it won't start, you might be dealing with a faulty door switch. This guide will walk you through the steps to diagnose and repair the door switch on your dryer.

Tools Needed

Smash Meter Screwdriver (Phillips or Torx)

Steps to Troubleshoot the Door Switch

Step 1: Safety First

Before you begin, ensure the dryer is unplugged from the power source. Avoid any electrical shock by taking this safety precaution seriously.

Step 2: Access the Door Switch

Open the drying door carefully. Identify the screws or clips that hold the door switch in place. Depending on your model, you may need to remove the front or door panel. Carefully detach the panel to access the door switch.

Step 3: Inspect the Door Switch

Visually inspect the door switch for any signs of damage such as cracks or burn marks.

Step 4: Test the Door Switch Using a Multimeter

Set your multimeter to the continuity setting or resistance mode. Disconnect the wires from the door switch to avoid false readings. Place one probe on one terminal of the switch and the other probe on the other terminal. To test, press the switch. For difficulty, have someone help you hold it down.

Reading

If the multimeter beeps or shows a low resistance near 0 ohms when the switch is pressed, the switch is good.

If there’s no beep or it shows infinite resistance (OL), the switch is faulty and should be replaced.

Step 5: Reassemble the Dryer

Replace the door or front panel if the switch is good. Reassemble the dryer. If the switch is faulty, replace it with a new one and reassemble the dryer.

Step 6: Test the Dryer

Plug the dryer back in and run a test cycle to ensure it operates correctly.

Tips for Troubleshooting

Always refer to the dryer’s user manual or service manual for specific instructions related to your model. If you are not comfortable performing these checks, consider contacting a professional technician.

This step-by-step guide should help you determine if the door switch in your Whirlpool electric dryer is functioning properly. Ensuring the proper operation of your dryer not only keeps your laundry efficient but also ensures your safety and the longevity of your appliance.
