Why is my dryer spinning but not producing any heat?


There could be many reasons as to why your dryer is still spinning but not producing any heat. Your dryer consists of so many different parts that any one could contribute to this problem. Listed below, we have the most likely parts that could be causing this problem. First, see if these parts are the issue, if not you may need technical help from a repair guide.

Thermal Fuse

This part is designed to prevent the dryer from overheating. Once this fuse has blown, it will not produce any heat and you will need to replace it. To see if this part is preventing your dryer from heating, check the thermal fuse for continuity with a volt/ohm meter. If it is open it will need to be replaced. To replace it, take the back panel off of your machine, unplug the wires from the terminals and pull the fuse out to check for a break. If broken, replace it with the same part.

Temperature Switch

The temperature switch determines the preferred temperature of the dryer as chosen by the user. This switch might be faulty if it is not changing the temperature of the drying cycles. You can test the switch for continuity, using a volt/ohm meter.


The timer is the source of power to the motor and if the timer contacts are defective, there will be no power getting to the motor. To fix this, go into the control panel. Remove the timer knob and then open the panel. Disconnect the leads from the motor and set your multimeter to RX100. Clip the problems onto the leads and check the meter. The timer motor will have to be replaced if it comes out as infinity.


Ignites the gas released by the gas valve. When the dryer is requesting heat, the igniter glows while heating. When the max temperature is reached, the gas igniter is located inside the dryer next to the gas valve burner tube. A multimeter can be used once again to check for its dependability. If the igniter doesn’t glow or spark, it might need to be professionally replaced.

High Limit Thermostat

The high limit thermostat allows power to pass through the thermostat when your dryer is operating normally. The heat source will not receive the required voltage to operate if the thermostat stays open. You can use a volt/ohm meter to test the thermostat for continuity. Remove the two wires on the ends of the thermostat and check for resistance. If there is no reading, the thermostat is open and will need to be replaced.
