We never realize how much we use our appliances until they break and how long can we go by without dry clothes?

Dryers are not complicated and in fact, we can easily determine what is wrong when they stop heating up, the drum stops rotating or it won’t turn on at all.

It is also not too difficult to perform the needed part replacement by yourself using the DIY method.

If your gas dryer won’t heat, here are the top 5 most common probable causes:

Be aware that every dryer model is different and you should use the specific model number when buying replacement parts.

The model number is commonly located in a label inside the door or you can also locate it in the user manual that comes with the dryer.

1- Blown Thermal Fuse

The thermal fuse is a safety device designed to protect the dryer from overheating. The fuse is normally located on the blower housing, although some dryer models have an additional fuse on the burner assembly.

If the dryer overheats the fuse will blow and cut off the power to the burner.

Be aware that the failure of the thermal fuse is often caused by the venting system being clogged with lint. To improve airflow recommend cleaning out the vent at least once a year.

You can use a multimeter to determine if there is a continuous electrical path present in the path. If not, the fuse has blown and will need to be replaced.

2- Bad Gas Valve Solenoid Coils

Gas dryers use one or more solenoid coils to open the gas valve and allow gas to flow into the burner assembly. A solenoid can fail several minutes into the drying process.

If You observe the igniter glowing and then shutting off without establishing a flame, then one or more of the gas valve coils have probably failed.

3- Faulty Igniter

The igniter ignites the gas in the burner assembly to create a flame if the igniter fails the gas will not be ignited and the dryer won’t heat.

As with the thermal fuse you can test the igniter with a multimeter to determine if it has continuity, if it does have continuity then the igniter is probably not the source of the problem.

4- Defective Flame Sensor

The flame sensor detects the heat emitted by the flame. If the flame sensor isn’t working the dryer won’t heat.

You should test the sensor for continuity at room temperature to determine if the part is defective or not.

5- Faulty Thermostat

The high limit thermostat is located on the burner assembly and monitors the dryer temperature, will shut off the burner if the dryer overheats.

The cycling thermostat normally located on the blower housing, it will cycle the burner on and off to regulate the air temperature.

If either of the thermostats fails the burner may not work at all, again you can use a Multimeter to test the thermostats for continuity to determine if the component has failed or not.
