How do you test a thermal cutoff switch?
How do you test a thermal cutoff switch?
Place the thermal cutoff switch on an electric skillet or griddle. Make sure the two prongs face up toward the ceiling. Set the thermostat on the griddle or skillet 25 degrees higher than the cutoff temperature of the switch. Touch both test probes from the multimeter to the prongs on the thermal cutoff switch.
How do I know if my dishwasher thermal fuse is blown?
Touch the left multimeter lead to the left side of the thermal fuse; touch the right multimeter lead to the right side of the fuse. Keep an eye on the multimeter needle; a needle that fails to move indicates a blown thermal fuse.
How do you test a thermal fuse on a LG dryer?
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.
How do you tell if a thermal fuse is blown without a multimeter?
Testing By Bypassing The Fuse If you do not have a multimeter, you can also test whether or not the fuse is working by bypassing the fuse itself. Simply detach the wires from the fuse, wire them together using a jumper wire and attempt to operate the dryer.
How do you test a thermal switch with a multimeter?
Touch the leads on your digital multimeter to both sides of the thermal overload switch. Watch the needle on the digital multimeter display to determine if your thermal overload switch needs to be replaced. A functional thermal overload switch will cause the needle to move to “0”.
How many ohms should a thermal fuse read?
The fuse has a compound inside that turns liquid at the temperature set point written on the fuse. When it turns liquidous, it causes the fuse to open. This means that any good thermal fuse should read “0” ohms across it, whether in or out of the circuit (like the others have said).
How do I reset the thermal fuse on my LG dryer?
To fix it, we’re going to do a factory reset.
- Unplug the dryer or trip the circuit breaker supplying power to the dryer off.
- While the dryer is without power, press and hold the Start/Pause button for 5 sec.
- Restore power and try to run a cycle.
