How To Test Dryer Thermal Fuse? 5 Easy Steps!

Are you wondering how to test dryer thermal fuse? Follow the steps to disconnect the appliance, search for a thermal fuse, get the thermal fuse uncovered, and use the ohmmeter afterward.

Once the dryer immediately stops working, it’s better to check if there’s a broken thermal fuse. Test it first before going and purchasing one, as it works as a safety mechanism in the home appliance interior.

How to test dryer thermal fuse

It stops the electric power flow when overheating takes just a few minutes before testing the thermal fuse. Remember that trying the thermal fuse in a dryer is similar to trying the thermostat. There is so much more to learn, so it’s best to dig into this article further!


Steps To Test Dryer Thermal Fuse

Below are steps to consider on how to test dryer thermal fuse:


Step #1. Getting the dryer disconnected

First, get the dryer disconnected from an electric power source and remove the plug. Be sure the device does not have an electric supply before testing a thermal fuse.


Step #2. Searching for a thermal fuse

Know where is the thermal fuse on a dryer. Search for a thermal fuse inside a home appliance but know that not many of these fuses fall in the same appliance part. It can vary from one brand to another and according to your home appliance type. Search for the thermal fuse in 2 sections behind a toe panel underneath and behind a rear panel.


Step #3. Uncovering a thermal fuse

Utilize a screwdriver when removing a panel to access a thermal fuse at the back. Get the screws removed using a screwdriver if you see a thermal fuse at the panel’s rear. Use the same equipment when pressing on metal clips and removing the board. The same is true if you see the fuse somewhere in the front. You can search for metal clips easily, like 4-inches on the edges of the panel. Place the board onto one side as it comes loose and let it stay there until finally testing and repairing it. A thermal fuse works as a plastic strip with two wires attached, so remove the two wires.


Step #4. Using an ohmmeter

Utilize digital multimeter or ohmmeter when testing a thermal fuse. Try to get the ohmmeter adjusted to the Rx1 setting so that the regular use of the device helps check if the fuse lets the electricity flow throughout the system. Enable the digital multimeter or ohmmeter from touching the fuse’ ends. The dryer must display the screen’s reading, so read it carefully to help determine the broken fuse. Never replace a fuse using another one if the ohmmeter needle has a 0Ω task. But then, install another thermal fuse once the ohmmeter has not kept a move.


Step #5. Analyzing results

After touching the probes, the ohmmeter shows a value that should fall fewer than 20 ohms. Check its pointer, mainly the analog ones. Higher than 200 ohms suggests a faulty fuse that sometimes shows a reading of infinity.


Steps When Testing Thermal Fuse Not Using Continuity Tester

Check for a possibly blown thermal fuse if there’s no continuity tester around. But then, it might require much effort, so search for the thermal fuse position. After finding it out, remove it as you disconnect both ends in the circuit. Complete as you connect both ends in a course to another wire. Place some wire pieces instead of a thermal fuse as you solder it.

Afterward, provide an electric supply in the dryer that when it works, it means to say it is faulty. If the dryer does not work, replace the wire using a fuse since issues exist in the appliance. Since no dryer will control a heating element, do not utilize it other than just testing it. Use some jumper wire when linking both ends in a thermal fuse. Check for possible completion in a circuit that may mean a bad fuse.


Thermal Fuse And Its Uses

The thermal fuse is a thermal cutoff type that breaks a circuit off after overheating. It works as a safety gadget in almost all electrical appliances. When a temperature increases at a specific level, it melts down that open circuit does not let the heat continue to other device parts, which saves them harm. The thermal fuse is a minor element playing an essential role in the safety and aversion of fires in an appliance.

The thing is that it is not possible to reuse or reset it. Changing it once it is not usable makes it function again. Still, the tool helps test the fuse’ working conditions. But if there’s no multimeter, it’s better to use other methods.


It’s A Wrap!

Now you learn how to test dryer thermal fuse by following the steps such as getting the dryer disconnected, searching for a thermal fuse, uncovering it, using an ohmmeter, and analyzing the results. It’s also given how to test the thermal fuse with no continuity tester. Plus, it’s good to know the thermal fuse and many of its uses! So share this information with some of your friends!
