If it does not heat , and you already checked the burner and the ignitor, then it is probably the thermal fuse at the back of the appliance.

See the following suggestions from Repairclinic:

No heat If your dryer doesn't heat, check these:

Igniter
Gas valve coils
Thermal fuse
Igniter Modern gas dryers use an electric igniter to ignite the gas from the gas valve. When it's working properly, the igniter glows bright orange. When it burns out, the dryer tumbles but there's no heat because the gas can't ignite. When the igniter burns out, you need to replace it. If the igniter is held by a tension bracket, you very well may need to replace the bracket too.

The igniter is inside the dryer housing, near the bottom front, usually in a cone-shaped metal tube (the force cone). It's about 2 inches long. It's mounted to the far end of the burner tube, and it has two wires attached to it--or to the tension bracket, if there is one.

Gas valve coils Watch the igniter. Does it glow bright orange, then shut off without igniting the gas? (When the gas ignites there's a large blue flame.) If so, there may be defective coils on the gas valve. Mounted on the top of modern gas valves, there are black electrical coils. The coils, when energized, open the gas valve. If one or more of the coils are defective, the valve doesn't open and the gas cannot ignite. Because it's often difficult to properly test the coils, it's usually best to replace both (all) of them at the same time.

Thermal fuse On many dryers, there's a thermal fuse (a heat-sensitive fuse that blows if the dryer overheats) mounted to the exhaust duct inside the back cover panel. The fuse is about an inch long. It's usually embedded in black resin and mounted in a white plastic housing.

If the fuse has blown, it has no continuity. When this happens, your dryer either just stops heating, or it doesn't work at all. Be sure to inspect the venting/heating system before replacing the fuse to put the dryer back into operation. (You can't re-set this type of fuse.)

Gas dryer runs but no heat. Took it apart cleaned all ducts and lots of years worth of dirt out of entire machine, looks brand new. Tested all components.


You did quite a bit of work. One other thing that controls the ignitor is called the flame detector. Its the black box looking thing mounted on the side of the big pipe the flame shoots into. Should be 2 wires going to it. A quick test to see if the ignitor comes on is to tie the 2 wires together. If you see the ignitor come on thats the bad part,

Hi, If you are having problems with your gas dryer not heatingthe most common problem is that the ignitor goes bad. Even though it glowssometimes it is still not working properly. if you dryer is gas check out this gas no heat tip....

Just hooked up my gas dryer. worked great thru 5 loads and then quit heating,help!


What did you do move it from one place to another place? You may have shifted the lint around and cause a limit to get tripped.
Here is the manual and more

A gas dryer has a burner assembly consisting of an ignitor, 2 coils, and a flame sensor. The ignitor does 2 functions. It lights the fire and confirms the fire is on like a thermocouple. When it is heated it holds in the coil. If the glowbar is not lit then the coils will not open. The ignitor must be heated to allow that. So if the ignitor and flame sensor is fine and the dryer works when cool but stops heating when hot I would say you need to replace the solenoids.

5 year old whirpool gas dryer heat shuts off after running for 10-15 min. Changed the thermal fuse.


Well you know you have heat for a little while so this must be something that quits when it heats up but runs when it cools back down. The ignitor is working and the flame sensor. The only other thing in that same circuit is those operator coils.e48860d.jpg They will quit when hot. They cool off and work some more. Replace those guys and your troubles will be ova.fec351c.jpg

No heat in gas dryer..replaced the ignitor..worked..then when he pushed it back into place it quit heating..the ignitor is lighting up but it is now not getting gas...and we have gas in the tank


If the ignitor glows then shuts off but does not lite (it will do this over and over) then the problem is one of the coils on the gas valve is not working. The coil kit is easy to replace the part number is 12001349 and should run about $30.00. They secure to the top of the gas valve just in front of the ignitor you replaced.

If the ignitor continues to glow and does not turn off then the part you need is the sensor part number Y303377 which mounts to the burner box real close to the ignitor and runs about $25.00

I hope this helps.

Dryer doesnt blow hot air.


I find that quite often the ignitor is out of alignment or the glass window is covered with lint.
a gas dryer blows air through a burner assembly to heat the air. The burner assembly consists essentially of a gas valve, ignitor and a flame sensor. If any part of the burner assembly malfunctions, the result will be low or no heat and slow drying of the clothes.
There are two common styles of ignitors, glow ignitors and spark ignitors. The ignitor ignites the gas either by heating up and glowing, or by sparking. If the ignitor fails, the dryer will not heat.

The easiest way to check the ignitor is to observe it. Remove the small access panel in front, select a high temperature setting and start the dryer. Watch the burner assembly, shortly after starting the dryer the ignitor should begin to glow or spark. If you see it glow or spark, then the ignitor is working.

Gas dryer is not heating up, after being moved


BE SURE THE GAS IS TURNED BACK ON. CHECK THE TEMP SELECTOR SWITCH TO BE SURE IT IS SETTING ON A SELECTION AND NOT BETWEEN SETTINGS. BE SURE IT IS NOT ON FLUFF AIR/NO HEAT. IF THAT IS ALL O.K., THERE ARE FOUR ITEMS TO CHECK IN THE HEAT CIRCUIT.
1. IGNITOR. CHECK FOR 120 VOLTS AT THE IGNITOR TERMINAL CONNECTION WITH DRYER RUNNING.
2. WATCH THE IGNITOR. IF IT GLOWS, CLICKS, GOES OFF WITH NO FLAME, ONE OF THE SOLENOIDS IS BAD. REPLACE BOTH.
3. IF THE IGNITOR COMES ON BUT NEVER SHUTS OFF,
THE RADIANT SENSOR IS BAD.
4. IF THERE IS NO RESPONSE FROM ANY OF THE CHECKS ABOVE, THERE IS A THERMAL FUSE ATTACHED TO THE EXHAUST PORT. IT MAY BE BAD. CHECK FOR 120 VOLTS ON THE TWO TERMINALS OF THE THERMAL FUSE WITH THE DRYER RUNNING. IF YES, THE THERMAL FUSE IS BAD.
