7 Causes Why A Gas Dryer Is Not Heating – How To Troubleshoot A Dryer Not Getting Heat









Gas dryer not getting heat? There are multiple parts in a gas dryer that can be faulty and cause the gas dryer to stop heating. If your gas dryer is not heating, see below for the 7 most likely parts and issues that can cause your gas dryer to stop heating. We will talk about each part and what it does.

Gas Dryer Not HeatingGas Dryer Not Heating

Remember when testing components or replacing parts in your gas dryer, always be sure the dryer is unplugged and there is no chance of gas leaking by turning off the gas valve.

1 – Faulty Gas Valve Solenoid Coils
These open the gas valves and let gas flow into the burner.
Check if the igniter is glowing and shuts off but there is no flame.
If there is no flame, the Gas Valve Solenoid Coil(s) are faulty and need to be replaced.

2 – Blown Thermal Fuse (on blower housing or on burner assembly)
The thermal fuse is most likely blown and if the thermal fuse blows, it cuts power to the burner.
This is most likely caused by a clogged venting system and the heat cannot escape.
Remove the Thermal Fuse and test it for continuity using a multimeter.
If the Thermal Fuse has continuity, this lets you know the problem is elsewhere.
If the Thermal Fuse has no continuity, it needs to be removed and replaced.
Clean out the venting system for your gas dryer with a wand type vacuum cleaner and suck out all lint.





3 – Faulty Igniter
Ignites the gas in the burner to create a flame.
If igniter fails the gas will not be ignited and the gas dryer will not heat up.
Remove the Igniter and test it for continuity using a multi-meter.
If the Igniter has continuity, this lets you know the problem is elsewhere.
If the Igniter has no continuity, it needs to be removed and replaced.

4 – Gas Supply To The Dryer
Be sure the gas supply line is OPEN and supplying gas to your gas dryer.
Check to be sure the gas supply line is securly connected to the wall and to the dryer.
If you find the gas supply line is damaged, remove and replace it.

5 – Defective Flame Sensor
This component detects the heat that is emitted by flame.
If the Flame Sensor is faulty, the dryer will not heat.
Remove the Flame Sensor and test it for continuity using a multi-meter.
If Flame Sensor has continuity, this lets you know the problem is elsewhere.
If the Flame Sensor has no continuity, it needs to be removed and replaced.

6 – Faulty High Limit or Cycling Thermostat (Located on burner assembly)
The High Limit Thermostat regulates dryer temp and shuts off the burner if the dryer overheats.
The Cycling Thermostat cycles the burner ON and OFF to regulate air temperature.
If either of these thermostats are faulty, the burner will not work.
Remove the Thermosats and test for continuity using a multi-meter.
If the Thermosats have continuity, this lets you know the problem is elsewhere.
If the Thermostats have no continuity, one or both needs to be removed and replaced.

7 – Faulty or Loose Wiring In Gas Dryer
A turned off gas valve or improperly connected gas line means no gas can get to the dryer.
If any of the wiring going to any of the parts above are loose, not connected, or damaged, this will cause the gas dryer to not heat.
Be sure to examine the gas dryer and check ALL wiring as sometimes it is just a simple wiring issue that is causing the dryer to not heat.
