As safety coils are going bad, they will work properly for a short period. Gas dryers use a set of solenoids (also called safety coils) to open the dryer’s gas valve automatically after the flame switch has opened, indicating that the igniter is hot enough to ignite released gas. There should be no resistance measured (a closed circuit, allowing electricity to flow). However, in electric dryers, the dryer won’t heat.ĭisconnect all connecting wires and check for continuity across the two wire contacts. The thermal fuse is the most common cause when a dryer has no heat.ĭryer Symptoms: On a gas dryer the dryer will not start. This fuse will often burn out due to clogged dryer ducting or a defective cycling thermostat. The dryer’s thermal fuse is a non-resettable safety fuse that is designed to break electrical contact to the dryer’s burner if the dryer becomes too hot.
If the igniter tests okay and is not heating, check the dryer’s thermal fuse, flame switch, hi-limit thermostat, motor contacts, and timer, in that order. A small amount of resistance should be measured in the dryer igniter to create the heat required for dryer burner ignition. Unplug the igniter and check for resistance through the dryer igniter contacts. And you will be putting on your dryer repair hat again soon.

Oils from your skin can shorten the new igniter’s life expectancy. The dryer igniter rarely fails, but if replacement is need for your dryer repair, be careful not to break the delicate new igniter or touch the part of the igniter that heats up. Also, if the dryer’s igniter is not heating up, either the igniter is broken, or it may not be receiving electricity from the timer or control board through the dryer’s thermal fuse to do its work. For the DIY dryer repair person, if the dryer igniter is heating up it is not the cause of a no heat or low heat problem. It receives electricity from the timer through a thermal fuse. The dryer igniter is responsible for igniting gas released from the burner valve. “Dryer won’t heat” or “Dryer not hot enough” Gas Dryer Igniter: (Note: Label all terminals and connecting wires before disconnecting them for proper reinstallation.) Igniter | Thermal Fuse | Hi-Limit Thermostat | Thermal Cut-Off | Cycling Thermostat | Thermostat Heater | Timer | Temperature Switch | Valve Solenoids (Coils) | Flame Switch | Burner | Thermistor | Moisture Sensor | Air Flow | Gas Supply | Dryer Won’t Start | Dryer Noises | Electric Dryer Repair All tests should be performed with the dryer unplugged and all wires connected to the part being tested unplugged. With a basic understanding of how the parts of a gas dryer work and a little DIY gas dryer repair coaching from yours truly, you will be able to repair many gas dryer problems yourself.
