How does a Kenmore dryer high limit thermostats work
Dryer high limit thermostats are located close to the heater and are wired in series with the heater. The contacts in a high limit thermostat remain closed at temperatures below 250 degrees. The contacts will open and interrupt the circuit to the heater when the operating thermostat, thermistor or electronic control fails to cycle properly. The most common condition that causes the high limit thermostat to operate are vent restrictions, blower failure or a defective operating thermostat or thermistor.
Vent restrictions are the number one reason dryer safety thermostats, thermal cutouts and high limit thermostats stop the heater from heating or open the circuit to the motor causing the dryer to shut down. |
