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.
What does cycling thermostat do in dryer?
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 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.
What causes dryer thermostat failure?
A frayed wire can cause a thermostat to keep going bad. A dryer will blow a thermal fuse if it’s close to overheating. Each time the thermal fuse blows it can interfere with a thermostat’s function and cause it to go bad, too.
What is the difference between thermal fuse and thermostat?
So a thermal fuse is a safety feature. Thermostat is not a safety feature. Thermostat is a measuring tool. Thermostats measure temperature.
Do dryers shut off when too hot?
When a dryer stops repeatedly during a normal drying cycle, it is typically due to the dryer overheating. When too much heat builds up in your dryer, lint or debris in the dryer vent line can ignite, resulting in a dryer fire. The overheat shutoff is the dryer’s last attempt to prevent a fire.
What happens when a thermistor goes bad in a dryer?
Bad Dryer Thermistor or Thermostat Symptoms of a bad dryer thermistor include air in the dryer that won’t heat up. If you have a faulty dryer thermostat, the dryer may keep the heat on for too long, causing the dryer to get too hot. If the cycling thermostat is defective, the dryer will not heat up.
Can I bypass dryer thermistor?
Subsequently, question is, how do you bypass the dryer thermistor? The thermistor is a device that is needed and unlike a thermal fuse cannot be bypassed by shorting its two leads together. Unplug the dryer and remove the leads from the Thermistor.
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 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.
Where is the cycling thermostat on a dryer?
The cycling thermostat can be found somewhere in the path of air that is leaving the drum. So, it could be found on the blower wheel housing or inside the venting/exhaust system. Dryer thermostats are usually oval shaped and about an inch and a half in length. Also, there should be two wires leading to each thermostat.
