by Mason Jones Appliance repair Services

High temperature leads the dryer of the washing machine prone to damage. In such circumstances, thermal fuse works as a savior.

You might have observed that the dryer of your whirlpool washing machine shuts down by itself without your command. This action is taken by a thermal fuse allocated on the dryer’s exhaust duct to prevent the dryer from burning.

A thermal fuse is basically a circuit breaker that is purposely designed to melt in the event of an over current condition. It works only once, and if it triggers during a high-exhaust temperature event, the fuse must be replaced.

In most of the Whirlpool Washing Machine models, the dryer doesn’t run after the burning of the thermal fuse.This leads you into the situation when you aren’t sure whether it befell due to the burnt thermal fuse or some other fault in your dryer.

To escape from this problem, our Whirlpool Appliance Repair experts in Monmouth County have come up with a solution. If you’re handy with do-it-yourself projects, you may be able to verify the burned thermal fuse, but make sure you have all of the tools you’ll need to begin.

If this task seems difficult, be conscious that many appliance repair experts in Monmouth County offer repair services, either by their own personnel or by independent installers. With the solutions given below, you will be able to verify whether or not your thermal fuse is burned out on a dryer.

Solution 1: Multimeter Test

This is one of the easiest and simplest methods to verify the thermal fuse is burned on a dryer. This test requires an electrical multi tester set at its lowest RX setting. To perform the test, remove the two wire leads from the thermal fuse and touch a multi tester probe to each wire terminal on the fuse. In case, you attain infinity reading on multi meter: fuse is fine, otherwise any reading below infinity: thermal fuse is triggered and need to be replaced.

Solution 2: Bypass Method

As per our appliance repair experts, By passing the fuse is the fastest method of detecting whether the fuse is burned. It is not a permanent fix. To perform this test, first, disconnect the two wires from the fuse and tie them together with a jumper wire, then turn on the dryer. If it runs and heats, the thermal fuse burned out and must be replaced.

Troubleshooting

Replace the existing fuse with new that exactly matches your dryer model. Then check the dryer for a reason why the fuse burned out. Ensure the power is still off before troubleshooting; examine the exhaust duct for obstructions that limited air flow. You may also need to replace the dryer cycling thermostat along with the thermal fuse. This is necessary because if this thermostat fails, it will possibly trigger the thermal fuse again.
