Troubleshooting A Dryer Heat Sensor
If you suspect that your dryer’s heat sensor is malfunctioning, we first need to diagnose it.
– Unplug the dryer from the electrical outlet to ensure safety.
– Locate the heat sensor. It is typically found on the heating element housing or the blower housing.
2. Accessing the Heat Sensor
– Remove the back panel of the dryer using a screwdriver.
– Identify the heat sensor. It is a small metallic piece attached to the heating element or blower housing.
3. Inspecting the Heat Sensor
– Check the heat sensor for any visible signs of damage such as burns, cracks, or discoloration.
– Ensure the heat sensor is securely attached and not loose.
4. Testing the Heat Sensor
– Use a multimeter to test the heat sensor. Set the multimeter to the lowest ohm setting.
– Touch one probe to each terminal on the heat sensor. A functioning heat sensor should give a reading of zero or close to zero.
5. Final Steps
– If the heat sensor does not pass the multimeter test, it may need to be replaced.
– Once inspection is complete, remember to replace the back panel of the dryer.
If it looks like the heat sensor is busted, we’ll need to replace it with a new one.

Replacing Your Dryer’s Heat Sensor
If you’re confident that the heat sensor needs to be replaced, then let’s get to work on swapping it out.
6. Replacing the Heat Sensor
– Purchase a new heat sensor that is compatible with your dryer model.
– Remove the faulty heat sensor by unscrewing it from the heating element or blower housing.
– Install the new heat sensor by screwing it into the same spot where the old one was located.
7. Reassembling the Dryer
– Once the new heat sensor is securely in place, it’s time to reassemble the dryer.
– Replace the back panel of the dryer by aligning it with the dryer frame and tightening the screws.
– Ensure all screws are tightened and the back panel is secure.
8. Testing the Dryer
– Plug the dryer back into the electrical outlet.
– Run a drying cycle to ensure the dryer is heating properly and the new heat sensor is functioning correctly.
9. Final Inspection
– After the test run, unplug the dryer and remove the back panel once more.
– Inspect the new heat sensor to ensure it is still securely attached and shows no signs of damage.
– If everything looks good, replace the back panel and plug the dryer back in.
10. Regular Maintenance
– To prolong the life of your dryer and its components, perform regular maintenance checks.
– Clean the lint filter after every use and inspect the heat sensor periodically to ensure it’s functioning correctly.
And that should do it!
