Grab your multimeter leads and then touch both ends of your fuse.

How to test a thermal fuse with a multimeter. To view all our multimeter ranges go to httpbitly1EdnDeoIn this video Josh shows us how to use a multimeter to check for faults in a thermal fuse. If you suspect a fault with a thermal fuse in your appliance you need to perform a continuity test on it using a multimeter- as the thermal fuse will display no visual indicators of its fault. Ive set up and calibrated this multimeter as per the instructions and.

Set up the multimeter. Connect the probes and set the dial to test for continuity. Touch each probe on one of the fuses leads or contacts.

Just like with the previous types a beeping multimeter is a good sign that the fuse is fine. Otherwise the fuse has blown and needs replacing. How do you test a thermal fuse on a dryer with a multimeter.

Set your multimeter to the R X 1 setting. Take each of your meters probes and touch one to each terminal. You are testing for continuity and you should receive a reading of either zero or infinity.

How to Test a Car Fuse with a Multimeter. Grab your multimeter leads and then touch both ends of your fuse. Your multimeter should now display the ohms on the screen.

If the fuse is in great shape the unit should get 0 ohms. You could also get a number close to 0 indicating the fuse is working. Test the fuse.

Listen for the multimeter to beep continuously as you hold the probes against the fuse. If you dont hear any noise coming from the meter then the fuse is blown and should be replaced. If youre using a digital multimeter.

To test the thermal fuse touch the red and black probe from the multimeter to the two wires attached to the thermal fuse. The test may be easier if your multimeter. In some models the thermal fuse is attached to the exhaust duct using screws.

You need to use the screwdriver to detach it from the exhaust duct and take it out. Bypassing the Dryer Thermal Fuse. When a multimeter is present you can check if the fuse is blown.

However when it is absent you can use the bypass method. Thats easier than said. This is usually done in the absence of ohmmeter as well as a multimeter or if you can remove your thermal fuse and take it to a local repair shop for analysis after bypassing the fuse you must do away with the electrical tape bypassing the dryer immediately after the test.

Next select OHMS on your multimeter. Place the two probes on opposite sides of the fuse you want to test. You should see a low reading of anywhere from 1 ohm to maybe 20 ohms.

If the display shows anything higher than 2 ohms disconnect one side of the fuse from the circuit and test the fuse again. It is advisable to use a multimeter to test a thermal fuse. But in case you dont have it there is only one way by which you can test it and that is by bypassing the fuse.

This can be done by detaching the wires from the fuse and connect them together using a jumper wire. If your dryer is not heating then you should test the thermal fuse thermal cutoff for continuity to see if it is good or bad. This free video shows step b.

How to Check a Dryer Thermal Fuse Unplug the dryer and remove the front access panel. Locate the blower cover–its the large object facing you at the bottom of the dryer. Remove the wires from the thermal fuse terminals to test it.

Set your multimeter to the R x 1 scale and touch the leads to the thermal fuse terminals to test for continuity. 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. We test fuses using the continuity mode because the main concept when it comes to how fuses work is continuity. If a multimeter detects no continuity you know that the fuse is broken.

This can happen because a fuse served its purpose and burned out thus breaking the continuity or it is possible that due to age or due to force in case that. You can use jumper wires to test whether a thermal fuse is faulty if you dont have a multimeter. It is simple physics where you use the jumper wires to complete the circuit and see if your ride-on car is working.

How to tell if a thermal fuse has blown. To test if your thermal fuse has blown touch the right side of your multimeter lead to the right side of the fuse and repeat with the left multimeter lead. If the multimeter needle fails to move this indicates the thermal fuse has blown.
