Maytag Gas Dryer Repair?

I hope can be useful...

Good luck.

Someone by the name "Jim Stansell" posted a while back:

Maybe those replies will help?

A guess might be the ignitor circuit. Some monitor the current through the ignitor to make sure it is dissipating sufficient power before opening the gas valve. That current may have to be maintained while the valve is open (maybe the ignitor must always be on when the gas is on). It sounds like something is faking a flameout and the valve closes until something cools. I'm glad it fails shutting the gas than leaving it open!

Another great website:

It just helped me fix a gas oven, which may have a similar ignition circuit.

Good Luck,

Jim

Most automatic gas appliances have a flame monitor for safety. It is likely the one in your dryer may be dirty, obstructed, or defective and it is cycling the main burner. Some flame monitors are optical and some are pyroelectric, I don't know which type your dryer has, but check this out. Carefully use a small soft brush to clear away dust.

... Wasted power is current squared times the resistance.
