Gas Dryer Not Heating? Don’t Worry, Here we will show you steps on how to diagnose and fix the issue. There can be multiple parts that can cause the Gas dryer not getting hot issues. If the dryer is not working, then it can make the daily routine more frustrating. Wet clothes will fill the room with more moisture and that typical wetty smell. If you are living in a cold climate area, then the dryer is the only option for drying the clothes. So, it becomes a more necessary appliance in your home, and if its not working then clothes will remain wet and wrinkled.
How to Fix Gas Dryer Not Heating
If your gas dryer is not heating, then it can be due to many parts inside the dryer which may be faulty and hence stop the gas dryer from heating. Also remember that, before you go for the test below or if you are replacing the parts of the gas dryer, make sure that the gas dryer is unplugged and also turn off the gas valve to stop any leakage of the gas. Also, do check out our article on Dryer Not drying clothes issue. Let’s look at some of the common causes and fixes for it below:
Fix#1: Faulty Igniter
The main function of the Igniter is to act as an electric conductor, which glows hot enough so that the gas can be ignited when you start the dryer. When the igniter reaches the optimum temperature, the gas valve will open thereby igniting the gas. You can find the igniter beside the gas valve burner tube. The igniter shape varies depending on the make and model of dryer. Usually it is coil shaped, but in some dryers it can also be flat.
The Igniter is a soft and very fragile component of the gas dryer. It can break easily and sometimes it can burn out. To check if Igniter is faulty or not, follow the steps below:
- Take a multi-meter.
- Remove the igniter.
- Test the continuity in igniter using multi-meter.
- If the continuity test fails, then you need to replace the faulty igniter.
Hopefully, after replacing the Igniter, Gas Dryer will heat up now. If the issue is not with Igniter, then proceed to the next solution.
Fix#2: Faulty Gas Valve Coils
Many newer gas dryers have Gas Valve Coils that controls the gas valve and let gas flow into the burner. You can find it on the top of the gas valve. Gas valve coils are controlled by the heat circuit. Sometimes these coils can get damaged or become faulty, then the has valve will be unable to open and hence you will get the Gas Dryer Not Heating Issue.
If Gas Valve coils become faulty, then you will observe that Igniter glows and shuts off, but the gas will not be able to enter the burner. You can also use a multi-meter to test for the continuity in the Gas Valve Solenoid coils. If you have determined that the Gas Valve Coils is faulty, then replace it with a new one to fix the issue.
Fix#3: Thermal Fuse has Blown
If your Gas Dryer is not heating, then it is possible that thermal has blown and if this happens then the burner will not get any power supply. Normally the most common reason for the Blown Thermal Fuse is that air circulation in the gas dryer is restricted or the venting system is clogged and hence heat is unable to escape. You can locate the thermal fuse near the exhaust duct. Please see the steps on how to troubleshoot and fix the issue.
- Take a stick vacuum cleaner and carefully clean out the Venting System and remove any dust and debrs which is clogging it.
- Now remove the thermal fuse.
- Take a multi-meter.
- Use a multi-meter to test the continuity of the Fuse.
- If you find no continuity, then replace the Thermal Fuse.
Hopefully the problem is solved. If not, then proceed to the next solution.
Fix#4: Gas Supply Line is Damaged
Make sure that the gas supply line has no signs of damage and it’s OPEN. Make sure that the gas dryer is getting the gas supply when the line is open.
Check all the connections and make sure that the gas supply line is securely connected to the dryer and the wall. If you have determined that the gas supply line is damaged, then you need to remove it and replace it with new one.
Fix#5: Defective Flame Sensor
The main function of the flame sensor is to detect heat the igniter, so that it can open the valve. It also detects the heat from the burner flame, so that it can keep the valve open. You can locate the flame sensor near the Igniter.
If the flame sensor is damaged or defective, then it causes the igniter not to glow or it can cause the gas valve no to open. If you see that igniter is not glowing, then you can check the radiant sensor to find the Issue. Please make sure that all power supplies have been disconnected before you proceed for testing.
- Remove the Flame Sensor.
- Use a multi-meter and test for continuity.
- If the test fails, then remove the old flame sensor with the new one.
Hopefully now you will not face the issue of Gas Dryer Not Heating. Still having an Issue? then let check the next component.
Fix#6: Faulty Cycling Thermostat
The main function of Cyclic Thermostat is to control the temperature inside the drum of a dryer. They switch on and switch off the heating element in a cycle, so that the temperature is maintained. You can locate it on the blowing housing. Sometimes it is also located in the internal airflow ducting.
Due to constant use, the Cycling Thermostat may get damaged or can become faulty. For fixing it, follow the steps below:
- Switch off the Gas Dryer.
- Remove the Cycling Thermostat.
- Use a multimeter to test for the continuity.
- If the Cycling Thermostat fails the test for continuity, then replace it.
Hopefully after replacing the Cycling Thermostat and your Gas Dryer Not Heating is resolved now. If issue still persists, then check the next step.
Fix#7: Faulty High Limit Thermostat
The High Limit Thermostat helps in preventing Dryer from overheating due to issues like when exhaust vent is restricted etc. If the Vent has become clogged, then it will be restricted, hence the high limit thermostat will trip and stop the power supply. High Limit Thermostat can only work a few times and ultimately it will fail and will be unable to reset, and hence the Dryer will not heat. To fix this, follow the below steps.
- Disconnect the Dryer.
- Clean the vent using a stick vacuum.
- Use a multi-meter and check for continuity in the Thermostat.
- If the Test fails, then replace the faulty High Limit Thermostat.
Fix#7: Check the wiring
Check if the gas valve is shut off or the gas line is not properly connected. In these cases the dryer will not get gas and hence will not get heated. Also check all the components and see if you can find any loose or damage wiring. if you find any faulty wires, replace or repair it.
You can also check the video below on how to troubleshoot and fix the Dryer not heating issue.
The above solutions can work on most of the dryers such as Samsung, Whirlpool, GE, MayTag, Kenmore, LG, Frigidaire, Amana, Electrolux etc. We hope that you are able to solve the Gas Dryer Not Heating issue.
