More than likely its the coils on your ignitor, there are two of them with four wires connected to them replace both

Sounds like you need to replace the coils on the gas valve. Just make sure your venting is clear 1st. If it is, the coils are easy to replace. Remove the front panel and the coils are on the bottom right hand side. Two screws and the bracket for both comes off. One has two terminals and the other has three. Real easy once you get into the dryer.

What part provides power to coils to ignite gas, and what would cause the igniter to suddenly shut off after five minutes?


Coil is probably bad, they get a crack in them and will not work. If you have a an ohm meter you can disconnect power and check it

My kenmore gas dryer works for 5 minutes then control panel flashs and won't heat th cloths


GOD IS GOOD !!!!
Gas Dryer no heat: or shuts down soon after heating CHECK:

Thermal Fuse
If the air flow in the dryer is restricted, the temperature in the heating chamber can get hot enough to blow the thermal fuse. If the fuse blows, it cuts power to the coils that control the gas valve. The fuse is usually mounted to the exhaust duct just inside the back panel. You can check its continuity with an ohmmeter. If, after disconnecting the fuse, you get any reading other than 0 when you touch the leads of the meter to its terminals, it has blown. There's no way to restore it -- you'll have to install a replacement.

Igniter and Gas Valve Coils
TEST with a multi meter: The igniter is an electric conductor that works like the element in an electric heater, glowing hot enough to ignite gas when you turn on the dryer. This conductor can burn out, and when it does, it may glow, but it won't get hot enough to ignite the gas. At times it may give a reading of continuity yet fail mechanically and not get hot enough to ignite flame though it gets hot and glows and even may show Ohms or continuity ( close circuit) ?

Occasionally, the Gas safety valve and the electric coils that control the gas valve are defective -- they can wear out when the dryer gets old. When this happens, the igniter glows, but gas never enters the heating chamber or does not stay consistant.
Performing a continuity test on either part will help you determine whether or not you need to replace it. But the coils should also be tested for amount of resistance as well as Ohms. As they may be showing ohms yet not putting out enough resistance to keep proper gas pressure flowing. Most coils should show at least 1300 ohms ( GIVE OR TAKE 150 OHMS). Anything significantly less Thus u get an ignition but then it soon goes back out. The flame does not stay lit.

Air Flow and Heat
The motor that drives the tumbler also drives a fan that circulates air through the heating chamber and the tumbler and expels it through the vent. If the air can't circulate, perhaps because of lint blockage, the heating chamber overheats, which prompts the cycling thermostat to turn off the gas. The thermostat resets when the chamber cools, but the chamber heats up quickly and the thermostat again shuts off the gas. The result is that the temperature in the tumbler doesn't stay hot, and your clothes take longer to dry, if they get dry at all.

Warning
There's a big difference between a dryer that doesn't heat up at all and one that just doesn't get hot enough to dry your clothes. In the first instance, the problem is usually a defective part, and things should be back to normal after you replace it. In the second instance, the problem is caused by restricted air flow, and you need to clear the lint filter and vents and take steps to prevent lint build-up. If you don't, you'll use more energy for drying than you need and the dryer may continue to malfunction. Worse, you may have a dryer fire.

Ge gas dryer heats but doesnt dry


if the flame is lighting you have lint blocking the air flow either in the dryer or in the vent line,also if you have a flame for the first 10 to 20 minutes and then the flame doesn't light you have bad gas coils located on top of the gas valve,when the coils are bad they can work for the first 10 to 20 minutes until the coils get hot and then they fail and you'll see the ignitor glowing orange but no flame,bad gas coils.then when the coils cool down they can work again.hope this helps.you can try removing the vent line from the back of the dryer and see if the flame stays on,if lint is blocking the air from blowing out the flame won't stay lit long enough to dry the clothes.

FRIDGIDAIRE GAS DRYER MODEL # GLGR642AS2 IS NOT DRYING CLOTHES BUT GAS IS IGNITING. THANK YOU. DON


Hi Don,
So let me get this straight, you are getting heat from the gas burner and the drum rotates but your clothes remain wet? You can check a few basic things to identify where the problem lies.. First off, have you checked the lint trap and cleaned it? Secondly, have you checked your vent system ( meaning : are you sure it is not clogged anywhere in the duct or at the end where it exits outside? If that's OK.. when your system is drying clothes.. do you get hot air flow at the end of that duct? If not, your blower may not be working ..You need to move that hot air out of the tub for the system to dry. Heat, Motion to move clothes, air flow from the blower and an unimpeded path via the vent duct to outside.. Hope one of these things to check gets you going. Regards...

I have a Maytag Atlantis Gas Dryer that will turn on, rotate, but will not get hot and dry the clothes. A load of clothes in the afternoon, didn’t dry, tried again but didn’t dry – went to bed after putting on auto dry - next morning the dryer was still rotating and didn’t turn off. No hot air – only cold air.

Maytag dryer does not maintain heat and clothes smell


Check coils on burner assembly. Often when a dryer heats initially and then stops heating a coils has gone bad.
