How does a cycling thermostat work?
The cycling thermostat in your dryer monitors the temperature in the blower housing and cycles the heating element or gas burner on and off as required to maintain the proper temperature.
How do I know if my dryer thermostat is bad?
After removing the cover from the dryer, perform a simple test on each thermostat, using an ohmmeter. Touch one meter lead to one terminal of the thermostat and the other lead to the other terminal. A reading of infinite resistance means that the circuit is broken — in other words, the thermostat is bad.
How do I know if my 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.
Can you bypass dryer thermostat?
The idea would be to bypass the thermostat, hi-limit or thermal cutoff one at a time and see if the dryer will heat. If it heats the thermostat is the problem. 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.
What causes dryer thermostat failure?
Dirty Lint Filter: A dirty or clogged tumble dryer filter will not only prevent the appliance from working effectively, but it can also result your tumble dryer becoming a fire risk, if it overheats. A further issue associated with clogged filters is that they can cause the thermostats to trip.
How do I reset my thermal fuse?
- Shut off the power. Unplug the dryer to disconnect electrical power.
- Remove the back panel. Move the dryer forward and use a 1/4-inch nut driver to remove the screws from the back panel.
- Remove the fuse.
- Install the new thermal fuse.
- Reattach the back panel.
- Plug in the dryer.
- Clean the exhaust vent.
How do you test a thermal fuse without a multimeter?
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?
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.
Will the dryer run if the thermal fuse is blown?
A gas dryer will run but won’t heat if its thermal fuse blows because the dryer overheated (usually because the vent is clogged, so check the vent path).
Should thermostat have continuity?
You are testing for continuity, and you should receive a reading of either zero or infinity. At room temperature, testing the thermostat should produce a reading of zero. But if a thermostat is tested when it is heated to its limit, a reading of infinity should be produced.
