Troubleshoot A gas Dryer That Won’t Heat With These 6 – Steps
Step-1. Thermal Fuse
The dryer thermal fuse is also known as the thermal cutoff fuse and the temperature fuse. The fuse is used as a safety mechanism, cutting off electricity to the dryer motor and the heating element to keep the clothes dryer from getting too hot. Note – Once this fuse has blown it cannot be reused. If your fuse has blown, you will need to check for blockage or lint build up in the clothes dryer vent hose or ventilation system, before installing a new thermal fuse, only to have it blow again.
The igniter is located inside of the burner assembly in a gas dryer, it is used to ignite the gas into flame for heat. If the igniter is bad, the gas will not light, and the clothes dryer won’t heat up. Using a multimeter or digital meter, you will need to test the igniter to see if it has continuity, if the test shows that it does have continuity the igniter is good. If the igniter does not have continuity then the part is bad and will need to be replaced.
Step-3. Gas Valve Solenoid Coils
The gas valve solenoid coils also referred to as the ignition coils are mounted just in front of the gas burner assembly. Their function is to open the gas valve to let gas flow into the burner assembly. If you can see that the igniter is glowing red hot and the burner does not light, it is likely that one or both of the coils are bad. Solution – replace both of the ignition coils.
Step-4. Cycling Thermostat
The cycling thermostat is normally located on the clothes dryers blower housing. It is used to cycle the heating element off and on during the drying cycle to regulate the temperature of the air entering the dryer. Using a multimeter, you will need to test the cycling thermostat to see if it has continuity, if the test shows that it does have continuity the thermostat is good. If the thermostat does not have any continuity, then the part is bad and will need to be replaced.
Step-5. High-Limit Thermostat
The high-limit thermostat is located on the clothes dryers heating element housing. It is used to monitor the dryers temperature, and will shut the heating element off if the dryer gets too hot. You will need to test the thermostat to make sure that it has continuity using a multimeter, if the thermostat has continuity the part is good. If the thermostat does not have continuity, the part is bad and will need to be replaced with a new one.
Step-6. Flame Sensor
The dryer flame sensor is used on a gas dryer as a safety device, the sensor is used to prevent high levels of gas from building up in the dryer. The sensor senses heat that is emitted from the igniter and monitors if it is hot enough to ignite the gas and light the burner. You will need to test the sensor for continuity using a multimeter. If the sensor does not have continuity, the part is bad and will need to be replaced.
