Arrow Additional Possible Causes

Hello timmer01. Welcome to my Gas Appliances topic and the Do-It-Yourself Web Site.

The information contained within the thread provided by the link below will contain almost every possibility for the problem. Very likely and possible the venting system is restricted. Remove entire vent tube from the back of the machine and note any differences. Dryer may or may not dry correctly. Link contains the needed steps to determine what to do depending upon the results of the test.

Solenoids may be defective.
Flame sensor may be defective.

Two most likely other possible causes is either the solenoids 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 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 inclosed 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:

The griding noises may indicate worn glider/slider pads which the drum rotates on. Information on this issue also contained in the thread povided by the 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.
