A dryer cycling thermostat monitors and controls the temperature inside your dryer while it’s operating. As your dryer heats up, the thermostat opens and interrupts the electrical connection to the dryer’s heat source. This allows the heating element and the air inside the dryer to cool down.

What happens when a dryer 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.
Why do tumble dryers have two thermostats?
Most tumble dryers will have one or possibly two control thermostats depending on the design. All should have an overheat thermostat fitted for safety in case the tumble dryer should overheat and this one will cut power to the heater or the whole tumble dryer.
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.
Why are my clothes so hot after drying?
The single most common reason why clothes dryer overheat is restricted airflow. When there's a blockage in the internal duct work, the hot air will become trapped inside the drum where it creates potential fire hazard. If you haven't done so already, remove and clean the lint filter.
How long does a dryer thermostat last?
There is a bottom line. The heating element can last between 8 and 18 years if the dryer is well-maintained and the vent and lint traps are clean.

How do you bypass a thermostat on a dryer?
The thermal fuse will look like a thin strip of white plastic with a wire coming out of each end. In order to bypass the thermal fuse, use electrical tape to tape the two ends together. The thermal fuse will then be bypassed. Turn the dryer on to a heat cycle for no more than 90 seconds.
What does the high limit thermostat do on a dryer?
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.
What are the 2 thermostats in a dryer?
There are usually 2 types of thermostats found on the modern day tumble dryer, Thermal Overload Cut-Out (TOC) and the Heat Control Thermostat.
Does a dryer heating element cycle on and off?
The heating element will cycle on and off in the same way as a gas dryer to maintain an average temperature determined by the thermostats sensitivity setting.
How does a dryer thermostat work?
A dryer thermostat works by using a temperature-sensitive plate to open a circuit to allow heat to develop and then close the circuit when the switch-off temperature is reached. After the temperature cools down, the temperature-sensitive plate goes back to its normal position and closes the circuit again.
Why do we need a thermostat for a dryer?
Repair Clinic says that a cycling thermostat cycles the heat on and off to maintain the proper temperature. The high limit monitors the dryer temperature and shuts off the heating element if the dryer overheats. There is also a difference between a thermostat and a thermistor.
What causes a gas dryer to not work?
In a gas dryer, a tripped dryer thermal fuse, faulty gas valve coils, failed igniter or faulty flame sensor will all prevent the heating element from working. Proper dryer maintenance, such as cleaning lint out of the exhaust system, can keep the dryer clear.
Why is my dryer not heating up?
Sears Parts Direct explains that there may be other reasons for air in a dryer not heating up. The culprit can also be the timer or electronic control board that controls the heat. Many other parts, such as the heater relay, thermal fuse or the thermistor, can also prevent the dryer from heating up.
What happens if your dryer thermostat is bad?
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.
What is a thermal fuse?
Dryer Thermal Fuse. The dryer thermal fuse is a different type of thermostat that is usually on the blower assembly inside the dryer. This is a fuse that if tripped (in other words, the circuit is broken), the dryer will not start. It's a safety feature designed to prevent the dryer from overheating to a dangerous level.
What is the difference between a thermostat and a thermistor?
Thermistors, on the other hand, are temperature-sensitive resistors that decrease or increase their resistance at different temperatures. Get the Best Mortgage Rate for You | SmartAsset.com.
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?
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.
Why is my dryer not getting hot?
Common reasons for an electric or gas dryer not heating are a tripped circuit breaker, clogged vent, and no gas flow. Other potential reasons include a faulty thermal fuse and broken heating element.
How can I test if my thermostat is working?
Raise the thermostat heat settings slowly. The thermostat should emit a clicking sound and the furnace should also make a sound. If the furnace does not make a sound, the thermostat is not sending a signal and needs to be replaced. Turn off the breaker to your furnace.
What causes dryer thermostat failure?
Blown Thermal Fuse 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.
Why is my dryer hot to the touch?
If your dryer is hot to the touch, it means heat isn’t being exhausted out of the dryer properly due to a blockage. A clogged dryer vent can cause the dryer’s heating element to overheat, leading to a fire. The dryer keeps shutting off before the end of the cycle.
Why are my clothes so hot after drying?
The single most common reason why clothes dryer overheat is restricted airflow. When there’s a blockage in the internal duct work, the hot air will become trapped inside the drum where it creates potential fire hazard. If you haven’t done so already, remove and clean the lint filter.
