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 know if my high limit switch is bad?
Check Your Limit Switch ” If the high limit switch was bad, the furnace should not fire. When the high limit switch trips, the flame/heating element will be shut off and the blower will continue to run to clear the heat. The blower will continue to run until either the system is reset, or the limit switch closes.”
What causes a thermal cutoff to go bad?
Clogged or restricted exhaust vent air flow is the most frequent cause of a thermal fuse blowing. Check the lint screen for lint or a build-up of debris that could be inhibiting air flow through the dryer. Before replacing the thermal fuse again, try these steps: Unplug the dryer to disconnect electrical power.
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.
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.
