Testing A Thermal Fuse With A Multimeter
Testing A Thermal Fuse With A Multimeter. The first step is to take the safety measure by unplugging the dryer from the wall outlet. Firstly, we have to find the fuse which controls the devices that are not working.

There are several benefits of testing a thermal fuse with a multimeter: 3) if there is continuity, the multimeter will register a low resistance reading, typically between 0 and 5 ohms. Testing a thermal fuse without a multimeter can be tricky, but it can be done.
If It Reads 1, The Fuse Has 100% Resistance, Is Blown, And Will Need To Be Replaced.
After you unplug the dryer, the power supply will stop. Place your leads on either side of the fuse. A good thermal fuse will have continuity, meaning that there is no break in.
Once It Is Removed, Use A Piece Of Metal (Like A Paperclip) To Bridge The Two Metal Contacts On The Fuse.
3) if there is continuity, the multimeter will register a low resistance reading, typically between 0 and 5 ohms. How to test a fuse with a multimeter. The resistance should go up, then after it cools should go back down to 0'ish.
The Multimeter Should Read Close To Zero.
Touch each probe on one of the fuse’s leads or contacts. Next, put one lead on each end of the fuse and check the reading. To test the thermal fuse, touch the red and black probe from the multimeter to the two wires attached to the thermal fuse.
You Need Some Way To Determine Whether The Fuse Has Electrical Conductivity Through It Or Not.
A short in the fuse can also cause an appliance to overheat. The first step is to remove the fuse from the appliance. 2) place one probe on each of the primary transformer terminals.
If The Wire Is Broken Or The Glass Is Black, The Fuse Is Blown.
Unless the vehicle is over. The test may be easier if your multimeter probes have small clamps or jaws on end. If you have a multimeter, you can test a transformer to see if it is working properly.
