How To Test A Dryer Thermal Fuse? 4 Easy Steps!

Do you know how to test a dryer thermal fuse? Well, if not yet, then you have come to the right place. We are here to help you out. You can test the thermal fuse simply by using an ohmmeter or multimeter. It is a tiny instrument that prevents flames. It’s only 2 inches in length. 

If the dryer exhaust heat is higher, a thermal fuse is activated. Whether this occurs, the fuse will trip and power down the dryer or even its parts. A single usage of a thermal fuse is required. The fuses should be changed if it blows throughout an event with a considerable heat release.

Once a thermal fuse is triggered, most dryers merely do not operate. The drum spins, as well as the dryer, run on certain types. However, the heat source seems not to. So if you want to learn more about this article, continue reading it. Let’s have a deep look at testing a dryer thermal fuse. 


Steps To Test A Dryer Thermal Fuse

The very first step you will do if a household device abruptly stops operating is to verify if, indeed, the thermal fuse has blown. You must always check it first whenever you get an excellent thermal fuse. A thermal fuse is a security measure built into a household device that prevents the flow of electricity if it overheats. Testing a thermal fuse usually just requires a little time. Let’s read how to test a dryer thermal fuse in just a few simple steps.


Step #1. Disconnect the home appliance

Before testing the thermal fuse, ensure that you have unplugged the household item from the power supply. Remove the plug to accomplish this. Before trying the thermal fuse, keep in mind there is no power to the household machines.


Step #2. Locate the thermal fuse

On the dryer’s exhaust duct, thermal fuses are fitted. To get to the fuse on a dryer, you usually detach the rear panel. While identifying and fixing the fuse, keep in mind the dryer is turned off. Typically dryers connect into a plug socket of 220-volt, and then you can turn it off by unplugging it. Thermal fuses come in a variety of sizes and forms. Some of these are made of plastic, while others have iron. 

Check for a tiny gadget located immediately on the upper edge of an exhaust duct, approximately the thickness of a penny to around 2 inches in length.  The thermal fuse can be found just behind the base foot panel or behind the back panel. 


Step #3. Unwrap the fuse

Disconnect the panel with a wrench to allow reach for the thermal fuse hidden beneath it. Remove the screws using the screwdriver if the thermal fuse is under the back panel. Whereas if the fuse lies at the front, have used the wrench to push the steel clamps and detach the panel.

The steel hooks are easy to spot, around 4-inches from either panel’s borders. Whenever the board becomes unfastened, set it away and keep it till you’ve completed all of the necessary tests and adjustments. The thermal fuse is a plain white piece with two cables connected. You need to cut two of these wires to uncover the thermal fuse. 


Step #4. Test the fuse by using the ohmmeter

To test the thermal fuse, you’ll require a digital multimeter, ohmmeter. You’ll need to switch the ohmmeter mainly to Rx1 mode. Suppose you’re unfamiliar with using an ohmmeter. In that case, it is a tool that allows you to determine whether or not the appliance’s thermal fuse allows electric current to pass into the systems. Let the ohmmeter or digital multimeter needles contact the fuse’s ends. A measurement must be displayed on the device’s screen. If you examine that attentively, you’ll be able to tell whether or not the fuse has blown. 

If indeed, the pointer of the ohmmeter reads zero(0), then there is no need to change the thermal fuse with such a fresh model. However, if the ohmmeter needle fails to move, you will have to replace the thermal fuse. A thermal fuse can’t be modified, and thus if one is found to be defective or damaged, it must be replaced right away.


Bypass Method For Testing Thermal Fuse

Bypassing a thermal fuse for a short period is reliable to determine if it has burnt out. This is easy to use either in a dryer-like manner or even to neglect to change the fuse after it’s on. Bypassing your fuse is just a fast way to see whether it’s blown. This isn’t meant to be a long-term solution. Start on the dryer after disconnecting the cables off the fuse, then reconnect them using power supplied. The thermal fuse has blown out and must be updated if it operates and warms. Click on these links to read related articles; know how to get the most out of your tumble dryer.
