Glow Coil, Solenoids and or Gas Valve

Hello Charles. Welcome to my Gas Appliances forum and our Do-It-Yourself Web Site.

The answer to the load on the motor question is no. If the drum is rotating at it's normal rotational speed, it would not effect the burner nor the gas valve.

The most likely problem is the solenoids. These parts are directly attached to the top of the gas valve. One of them is defective causing the noise, the burner to fail to allow gas to pass to the burner, etc.

Solenoids are electrical current using devices. Solenoids warm up and often drop out when they become defective. Drop out means ground out, lose electrical connection internally and close off the gas supply.

Losing connection or electrical current supplied to a solenoid for any reason, the solenoid demagnetizes. Once it losses current the tiny disk it holds open drops down closing off the gas passage.

A solenoid is nothing more then an electro magnet. Energized, it will be a magnet used to hold open a tiny disk off it's valve seat, allowing the gas to flow thru.

Replacing the solenoids, sold in pairs only, should resolve the problem. Be sure to unplug the dryer first and turn off the gas supply to it before attempting any repairs.

Remove both solenoids off the gas valve body by removing the hold down cover plate and replace them both, if defective.

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.

Another possibility could be a defective gas valve. Remove entire unit as an assembly. Take the entire assembly to your local appliance parts store for testing. Gas valves are not repairable. Replacement is the only option if defective.

For additional information, repair instructions etc. read the other questions within this forum pertaining to dryer topics. The questions already asked describe like or similarly related problem descriptions as your question.

These prior postings and any or all the replies offered within them contain all the required information needed pertaining to the many possible problems with the dryers unit like your describing.

Retail appliance parts dealers can also help determine what the possible problem may be. Bring the make, model & serial numbers.

DRYER SERVICE TIP:
It's always adviseable to clean the entire exhaust venting system every 2 years. Or during any dryer maintenance and or repairs.
