Why Is My Gas Dryer Not Heating Up? – Top 7 Causes and Solution

Are You facing gas dryer not heating problem? Let us help you! There are many different parts that can cause your gas dryer to stop heating. If you’re experiencing an issue with your gas dryer, see below for the most likely parts and issues.

Gas dryers are pretty simple, but they can still screw up. They work with three parts: The igniter, the gas burner, and the blower. With a basic understanding of the parts and a little coaching from this DIY expert, you will be able to fix many problems yourself. All tests should be conducted with the dryer unplugged and all wires connected to the part being tested unplugged.

Faulty Gas Valve Solenoid Coils

Have you ever wondered how a gas dryer works? It’s pretty simple! A typical gas dryer is equipped with a gas valve. This valve opens when the dryer is started. The valve is directed to open by use of an electrical solenoid. When the dryer is started, the solenoid activates and opens the valve automatically.  As long as the gas valve opens before the dryer stops, coils are functioning properly. If the dryer does not start, one or more of the coils may be broken.

The gas valve coils are on top of the valve. The easiest way to test them is to use a multimeter. If there is no continuity while testing the coils, then the problem might be caused by a faulty coil or by a disconnected wire. The coils can be tested after gaining access to the area where the gas valve is located.

When you’re ready to replace your dryer coil, make sure you disconnect the gas hose and unplug the machine. Turn off the gas valve and remove the coil(s). If the meter reading shows 1000-2000 ohms, it’s time to replace the coil.

For starters, contact the company that made your dryer and order replacement coils. After you get the coils, head back to the house and replace them. When you’re done, turn on the dryer and see if it’s working again.

Blown Thermal Fuse

If the thermal fuse in your gas dryer blows, you can replace it and your dryer will be as good as new! A thermal fuse is a safety feature of a gas dryer that prevents an overheating condition that could potentially cause a fire. To find the fuse, just check near the blower. Determining the kind of gas dryer you have is as easy as checking the fuse’s location.

The thermal fuse might be blown if the burner is not getting power. This could be caused by a clogged venting system or an obstructed gas line.

The dryer is not heating. It is possible that the dryer’s thermal fuse is blown, which prevents the dryer from working. To test this possibility, you can use a multimeter to check for continuity.

You should unplug the dryer and remove the access panel in the back. If you find the blower, you’ll be able to take out the thermal fuse. Check for continuity using your multimeter, and when it reads zero (infinity), replace the fuse.

If you’ve replaced a blown thermal fuse before, you probably know that the dryer has an exhaust vent. It’s important to check the venting whenever you need to replace a fuse.

Faulty Igniter

The dryer igniter is a small device that connects to the gas valve and receives electricity from the timer. It is responsible for igniting the gas inside the burner.

The igniter is the part of the dryer that needs to reach a specific temperature for it to work. If the igniter doesn’t reach the proper temperature, then the solenoid (which opens and closes valves) won’t be able to work and gas won’t flow. If you suspect that the igniter is faulty, you can test it by touching it with a multimeter. Replace the faulty igniter with a new one.

To fix a broken dryer, remove the access panel and disconnect the gas hose and power cord. Remove the old igniter and replace it with a new one. Place the access panel back on and reconnect the gas hose and plug in the power cord. Test the dryer to ensure it is heating properly.

Defective Flame Sensor

You might not know this, but the radiant flame sensor in a gas dryer is an important safety feature. If the sensor doesn’t work, it won’t tell the valve to open and allow gas to flow into the dryer. When the sensor determines that the tip of the igniter is at the desired temperature, it signals for solenoids to open and let gas flow: and voila: ignition!

If the gas is not coming on, first make sure the igniter is heating up. If it is, make sure the radiant flame sensor is okay. You can test the sensor with a multimeter and replace it if it is broken. To check the sensor you’ll need to disconnect the gas hose and unplug the power cord from the outlet.

If the flame sensor is not functioning correctly, it will need to be replaced. The sensor should be located near the igniter. First, you’ll need to remove the sensor with a screwdriver. Then you can use a multimeter to test it, and replace it if it has an incorrect reading. To get a new sensor, you need to contact the manufacturer and order one.

Defective High Limit Thermostat

The hi-limit thermostat regulates the heat in your dryer. If it senses that the dryer has become too hot, it will break the electrical contact to the dryer’s burner or heater to prevent further damage. It will also turn off the dryer’s burner or heater if the ducting becomes clogged and blocks airflow.

When things go wrong with your dryer, you’ll know it. However, the cause of the issue might not be immediately apparent. There are two main symptoms. Usually, people say their dryer takes forever to heat up or doesn’t heat at all. It’s important not to just blame the thermostat. This component is usually reliable and it’s rare that it’s the problem.

To check the thermostat for proper operation, unplug it from the wall, remove the back panel, and take out the thermostat to test it. If it doesn’t get a “zero” reading (infinity), the high limit thermostat is faulty. Replace it with a new one.
