Whirlpool Dryer heat problem

I know people on here have probably heard about dryer problems a million times by now. Well, here is my problem. I have a Whirlpool gas dryer. It is only about 6 years old. As of about a week ago, it started having this problem. It took me a while to find out exactly what it is doing. My last test was with the exhaust tubing removed while I watched the burner through a couple of slots. It will heat up initially and seem to work fine for about 10 minutes. The burner will startup fine and go down and then come back on and just continue cycling as it normally should. At least I think that's normal for a dryer to cycle the burner off and on in order to keep it from getting too hot. After 10 or so minutes, the burner stops coming back on. I watched the flame TRY to turn on and start flickering but then heard a slight clicking noise and the flame went back down. It continues this until I shut it off. Even, if I turn it back on right away, it will not work normally even for the first 10 minutes. I don't know how long to wait before it will give me some heat at the beginning again. I've done some online reading about dryer problems but it just seems like there are so many possibilities that I'm not even sure where to start. Timer seems to work fine. Any ideas would be appreciated.

Replace the gas coils. They heat up and open giving your problem.

Hello budosborne and Welcome to the Gas Appliances topic and the Do-It-Yourself Web Site.

Two most likely causes is either the solenoids (coils) on top of the gas control valve or the radiant flame sensor on the burner flame hood.

Ohm test the flame sensor with electrical power to dryer turned off or machine unplugged. Ohm meter should show a closed circuit. (Needle swings all the way over to right side of meter.) If circuit closed, sensor is okay.

Solenoids (coils) on top of gas valve may be defective. There are two. Any one of them fails both get replaced. Sold and installed in pairs only. Remove them from the top of the gas valve by removing the entire gas valve assembly first.

To accomplish this task, the entire burner and gas valve must be removed. Then the solenoid coils can be removed from the top of the gas valve and replaced.

The gas inlet pipe to the right side of the gas valve has a tiny on/off gas shutoff valve. Turn it off, lever opposite it's current on position. The nut on the gas supply pipe near the gas valve is counter threaded, which means it turns opposite the norm to loosen it.

There will be other sheet metal screws securing the gas valve and burner assembly to the dryers base. Once the entire gas valve is removed, take it and the make, model and serial numbers of the appliance to the local appliance retail parts store.

Remove both solenoids off the gas valve body by removing the hold down cover plate and replace them both if defective. They are sold only in pairs.

Or take the entire gas valve unit to your local appliance parts store and have the entire assembly and all the parts tested individually and as an assembly.

Once at the store, the salesperson can be sure the replacement parts are the correct ones. Replacing the solenoids is simple and the parts come with full instructions enclosed in the packages.

Defective Gas Valve could be the problem. Remove entire unit as an assembly. Take the entire assembly to your local appliance parts store for testing. Gas valves are not repairable.

CAUTION: Do Not attempt to repair the gas valve. This is a non repairable item. Replacement is the only option, if defective.

Gas Dryer Help Link:

Retail appliance parts dealers can also help determine what the most likely possible problem may be. They will need the make, model and serial numbers. Appliance parts dealers are an excellent source for original replacement parts and problem resolving matters. Dealers are listed in the phone book under appliances.

I am having a problem with my Whirlpool dryer not heating. Replaced coils, igniter, flame sensor. Have had entire gas assembly bench tested and works fine in shop. When I put back in dryer without gas hooked up, igniter cycles on and off, but when I hook up gas line, igniter glows and gas won't flow. Also, even on air cycle, igniter glows. HELP!! Dryer worked before having coils replaced, but was taking a long time to dry clothes. Coils were working, but weak.
