How do I know if my dryer thermal fuse is blown?

How to Tell if a Thermal Fuse is Blown

1. Unplug your dryer and ensure it is no longer connected to the gas or electric.
2. Locate the thermal fuse, as above.
3. Disconnect the thermal fuse from the wires.
4. Test the fuse with a multimeter.
5. If the needle on your multimeter does not move, your thermal fuse is blow.

How do I know if my dryer fuse is bad?

Touch the black lead to one of the fuse’s terminals and the red lead to the other terminal. If the meter display shows zero Ohms of resistance, the fuse has electrical continuity and has not blown, indicating that another component in the dryer is likely defective and preventing the appliance from running or heating.

Can I bypass the thermal fuse on my dryer?

The thermal fuse will look like a thin strip of white plastic with a wire coming out of each end. In order to bypass the thermal fuse, use electrical tape to tape the two ends together. The thermal fuse will then be bypassed. Turn the dryer on to a heat cycle for no more than 90 seconds.

How many ohms should a dryer heating element read?

The ideal reading for a tumble dryer element is between 20 and 50 ohms – so any reading significantly outside of this range means the element is faulty and needs to be replaced, in this case this element in this video is fine.

What happens when a thermal fuse blown on dryer?

A thermal fuse will blow when the temperature gets too high, not when it’s drawing too much current. When it blows, the dryer stops generating heat. It’s necessary to replace it before the dryer will run again.

How do you test a thermal fuse to see if its good?

Multimeter Test Remove the two wire leads from the thermal fuse and touch a multitester probe to each wire terminal on the fuse. If you get a reading of infinity, the fuse is fine. Any reading less than infinity indicates a triggered thermal fuse you will need to replace.

Does a thermal fuse reset itself?

A thermal fuse is a cutoff which uses a one-time fusible link. Unlike a thermal switch which may automatically reset itself when the temperature drops, the thermal fuse is more like an electrical fuse: a single-use device that cannot be reset and must be replaced when it fails or is triggered.

Is the heating element in a dryer supposed to be red hot?

Occasionally, a red glow may be seen inside the dryer drum. This is normal. The glow is from the heating element and is most noticeable if the cycle has been interrupted to remove or add an article of clothing. During the drying cycle, the element heats and glows.

Why is my clothes dryer not getting hot?

Common reasons for an electric or gas dryer not heating are a tripped circuit breaker, clogged vent, and no gas flow. Other potential reasons include a faulty thermal fuse and broken heating element.

How can I test my dryer heating element?

To see if a dryer’s heating element is bad or not, a homeowner needs to test the heating element. To perform this test, the heating element, a screwdriver, a continuity tester and needle-nose pliers are needed. Before starting, the dryer should be unplugged, and the screw on the vent clamp should be loosened and released from the back of the dryer.

How can you tell if a dryer is a gas dryer?

Another method for checking whether you have a gas or electric dryer is to pull the machine a few inches from the wall – just enough so that you can shine a flashlight behind it. If you see one cord attached to the dryer, it’s electric. If you see a cord and a thin stainless steel connector, your dryer is gas.

How do you replace a thermal fuse on a dryer?

To replace a thermal fuse, unplug the dryer, remove the back panel, disconnect the wiring to the fuse, remove the screw holding the fuse in place, remove the fuse, and replace it with a new one.

How do you test a thermal fuse?

Since you can’t tell if a thermal fuse has blown out simply by looking at it, you’ll need to perform a continuity test. A continuity test will determine if a continuous electrical path is present in the fuse. If the fuse has continuity, it should be functioning properly.
