Is it OK to bypass a thermal fuse?

Bypassing a Dryer Thermal Fuse If you do not have access to a multimeter or ohmmeter, you can momentarily bypass the thermal fuse. Operating a dryer with a bypassed thermal fuse is both unnecessary and unsafe, so a bypass should only be done long enough to troubleshoot a potential problem.

Are thermal fuses necessary?

The manufacturers of domestic appliances are rightly concerned that under fault conditions, the temperature inside the appliance could rise without limit, and cause a fire. A thermal fuse ensures that this doesn’t happen.

Can you bypass a thermal fuse on a microwave?

A thermostat fuse is designed to protect your microwave from overheating. If your thermal fuse has been activated by your microwave overheating, your microwave will stop working. Never bypass your microwave oven’s fuse!

What is a thermal disconnect switch?

What is a Thermal Cutoff Switch? A thermal switch is an electromechanical device which opens and closes contacts to control the flow of electrical current in response to temperature change. It cuts off the current to critical machinery when a temperature limit is exceeded preventing potential burn out or failure.

Do LED lights need thermal protection?

LEDs are typically around three times as efficient as traditional forms of incandescent lighting and yet they will still fail prematurely if not mounted onto a bulky heat sink. A robust thermal system design must account for all elements of the lighting system including the driver.

How do you bypass a thermal fuse on a fuse box?

Locate the thermal fuse. 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.

How do you bypass a thermal fuse on a whirlpool 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.

When to replace a thermal fuse on a Maytag dryer?

Replace the Fuse if Indicated. If the dryer starts to run warm once the fuse is bypassed, the fuse was the problem and needs to be replaced immediately. If it still does not operate correctly, the issue is likely a faulty heating element. Replace the thermal fuse immediately if the dryer operates normally with the thermal fuse bypassed.

How do you test a thermal fuse with a digital multimeter?

The probes of the digital multimeter or ohmmeter need to touch the edges of the thermal fuse to read it correctly. Once the connection is made, a reading should appear on its screen. If the needle on the ohmmeter changes place to 0, the thermal fuse is fine and does not need to be replaced.
