What does the cycling thermostat do?
What does the cycling thermostat do?
What Does a Dryer Cycling Thermostat Do? A dryer cycling thermostat monitors and controls the temperature inside your dryer while it’s operating. This thermostat has an electrical circuit that is usually closed, allowing electricity to flow through it freely and deliver power to the heating element.
What does a dryer high limit thermostat do?
A dryer high-limit thermostat (High Limit Thermostat, Hi-Limit Thermostat, Dryer High-Limit Thermostat) is a switch that is actuated by temperature change. This high limit thermostat acts as a safety mechanism to keep the dryer from overheating. If your thermostat is malfunctioning, your dryer may not heat.
Is a thermal fuse the same as a high limit thermostat?
The thermal cut-off (fuse) is meant to trip at a higher temperature than that of a high limit thermostat. This is a one time use fuse, so when it does trip, you must replace it. The hi-limit thermostat acts as a safety mechanism that keeps the dryer from overheating.
Why do tumble dryers have two thermostats?
Modern dryers usually have more than one thermostat: a cycling thermostat that turns the heating element on and off to keep the temperature even and either a high-limit thermostat or a thermal thermostat that cuts power to the heating element if the dryer overheats.
What temperature is a high limit thermostat?
200 degrees Fahrenheit
High Limit Thermostat (Limit: 200-30) Specifications. This high limit/safety thermostat is used on many of Maytag’s brands of gas and electric clothes dryers. With this thermostat, a dryer’s heating element will cut out if the internal temperature reaches 200 degrees Fahrenheit.
What is the purpose of high limit?
During normal operation, the high limit switch’s main job is to control when the blower fan turns on and off. The blower fan needs to be controlled by the limit switch rather than the thermostat. This is because you don’t actually want the blower fan to turn on and off at the same time as the gas burner.
Is thermistor same as thermal fuse?
The temperature rating of the two devices differs. The maximum operating temperature of PTC thermistors is 85 degrees Celsius while the maximum operating temperature for fuses is 125 degrees Celsius. Both devices will require derating when the temperature is above 20 degrees Celsius.
What happens if high limit thermostat fails?
If the dryer does heat up, a bad dryer thermostat can result in loss of temperature control. 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.
