How To Test A Thermal Fuse With A Multimeter. This option is represented by the omega symbol. Set your multimeter to the r x 1 scale and touch the leads to the thermal fuse terminals to test for continuity.
Turn the wheel to ohms. Replace a fuse that does not. If you get a reading of infinity, the fuse is fine.
In Some Models, The Thermal Fuse Is Attached To The Exhaust Duct Using Screws.
Turn the wheel to ohms. Replace a fuse that does not. When a multimeter is present, you can check if the fuse is blown.
This Can Be Done By Detaching The Wires From The Fuse And Connect Them Together Using A Jumper Wire.
To test the thermal fuse, touch the red and black probe from the multimeter to the two wires attached to the thermal fuse. The thermal fuse cuts off power to the microwave if the microwave overheats. If you get a reading of infinity, the fuse is fine.

How do you test a thermal fuse on a dryer with a multimeter? Set your multimeter to the r x 1 scale and touch the leads to the thermal fuse terminals to test for continuity. This free video shows step b.
This Video Demonstrates How To Test A Thermal Fuse On An Electric Or Gas Dryer.
If your dryer is not working you may want to check these first. Touch the two leads together from the meter, and you should get a reading close to zero. Set your multimeter to the r x 1 setting.
Take Each Of Your Meter's Probes And Touch One To Each Terminal.
To determine if the thermal fuse has blown, use a multimeter to test it for continuity. By doing this, you will have successfully bypassed the thermal fuse. At room temperature, testing the thermal fuse should produce a reading of zero.
