The problem is definitely the gas valve solenoid coils sitting on top of the gas valve assembly. There are two of them, one with three prongs and the the has two, and held by a bracket. They must be working fine when cool but eventually fail when get hot. Simply replace the coils and the dryer should start heating. Just make sure to disconnect power to the dryer before attempting any repair works.

Pull the lint filter out and remove the screws near the opening.

    Remove the rear cover and bypass the high-limit thermostat on the heater box at the back of the dryer as shown then plug in and start the dryer. Simply pull the wires off then tape them together or jump a wire between them. Replace the high limit thermostat if the burner does not shut off prematurely. Do not use the dryer with any part bypassed. Bypassing any component is for troubleshooting purposes only. Disconnect the dryer from the power source before attempting any repair works.

    Bypass the cycling thermostat if bypassing the high-limit thermostat does not prevent the burner from shutting off prematurely. Plug the dryer in then start it. Replace the cycling thermostat if the burner does not shut off prematurely.

My gas dryer wont ignite. where do I start trouble shooting

Model number would help but I'll give some general info. Most Kenmore dryers are usually made by Whirlpool so I'll give info for that type dryer. The 1st thing to check on a no heat is if the glow bar ignitor is coming on. At the cycle start it should glow red hot or orange. If no glow the glowbar may be burned out and needs replaced. This is the most common problem in a gas dryer. If you see the orange glow for about 15 seconds and it goes out ---that is normal. That usually means you may have a bad magnetic coil on the top of the gas valve. There are actually 2 coils on the valve and if either one goes bad the valve will not open and let gas through to ignite. They need tested with a multimeter. Thats the 2 most common problems with gas dryers.

Kenmore gas dryer 80series model 110.c72852101

if you hear the valve clicking but no gas the valve is bad.when the burner lights theres a probe that senses that it is lit and sends a microvoltage back to the controller to tell its lit.check to make sure all ground wires are grounded to a clean metal surface.

Whirlpool gas dryer

Check to see if there is a glow at the burner when you start it up. If it glows then the igniter is good. If not it could be a thermal fuse, bad igniter, flame sensor or a bad cycling thermostat. If it glows then it could be the gas valve coils.

I have a whirlpool gold gas dryer model#GGQ8858JT1. When I push the start button the dryer starts and spins but the heat does not come o

does the igniter glow? If not check for 110 volts at igniter .
Check for 110 volts at gas valve if no volts check hi limit thermostat , operating thermostat, safety switch on motor,
the coils on the valve & the timer contacts that feed the voltage to the burner.

Whirlpool gas dryer Model #WGD5530SQ0 not heating properly

If your dryer heats when you first turn it on and after a few minutes it does'nt. check the ignitor to see if it is glowing. It should glow bright then you will hear a click and the burner will light. If the ignitor glows bright but you hear a click but no flame and if you watch this for several minutes and this process continues of glow then glow goes out no flame, then you have a bad burner coil. There are 2 black solenoids sitting on top of gas valve. One of them is shorting out after it warms up. Replace both solenoids. You can usually get them as a kit from parts store.

I have a kenmore gas dryer is it good if on # 1 coil on #1and 2 i get1328 ohms 1and3 i get 528 on #2 coil i get 1220 ohms

On the gas valve are one or two coils (solenoids) used to open and close the valve to control the flow of gas. If a coil fails, gas will not flow and the dryer will have no heat.

The easiest way to diagnose a problem in the burner assembly is to observe the burner operation. Remove the small access panel at the bottom, front of the dryer, select a high temperature setting and start the appliance. Watch the burner assembly, shortly after starting the dryer the ignitor should begin to glow. Next you should hear the click of the gas valve coil and a flame should ignite. The flame should be mostly blue and it should remain on for a minute or more.

If the ignitor glows for several seconds (up to 15 seconds) and then goes out, the problem is probably the coils (solenoids). If the ignitor glows and stays on, then the problem is usually the flame sensor. If it ignites and then quickly goes out, it is most likely a problem with inadequate air flow.Test the coil for resistance using a multimeter. Set the multimeter to the ohms setting X10. Place a probe on each terminal. The multimeter should change from a reading of infinity to roughly 1300 ohms (+/- 150 ohms) when the probes touch the terminals. If the reading is infinity or substantially different from 1300 ohms, the solenoid should be replaced.

After starting my GE gas dryer , the burner fires and everything seems fine . The burner stays on for a few minutes and shuts off like it's supposed to . After a few minutes , the glow element turns on to...

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.

I have a whirlpool dryer will not heat

Either the glow bar is weak or the valve coil is failing. Measuring the amp on the coil is the only way to be sure. If the burner lights once in a while it is most likely the coil,

Model GGW9200LW0 Gas Dryer Unit does not heat, I checked and cleaned the vent line and I also changed the fuse. Still no Heat, any suggestions?

If this is indeed a GAS dryer, the next thing I would do is verify that your igniter is working. If you can see inside the dryer (under the drum where the burner assembly is), there should be an orange glow coming from the igniter after you start it. In simple theory a gas dryer works like this:

1. Press the start button, dryer drum begins to tumble, igniter begins to glow.
2. Once the igniter reaches a specific current level (as determined by the type igniter you have), the gas safety valves open and you have ignition.

Typically, the common fail item is the igniter. They simply wear out with age. I would recommend reviewing the following link to learn a little more:

I know the link is for replacing an igniter on a gas range, but the type of igniter and theory of how it operates is essentially the same. It is common to have an igniter STILL glow, but not ignite, because it has become weak and will not draw enough current.

Another problem associated with no ignition are the gas coils on the burner assembly. Your dryer should have two of them. One is the pilot position coil (3 terminals), while the other is called the main coil (2 terminals). If one of these coils is defective, it is recommended that BOTH be replaced. has an excellent exploded view illustration of the parts I've discussed here. Just type in your COMPLETE model number and look under the "Burner Assembly" heading. The igniter is listed as item number 4 (part #279311) and the coils are listed as items number 13 (part #694540) and 14 (part #694539).

I hope you find this information helpful. Let me know if you require additional assistance.
