Gas dryers work by burning gas and circulating the hot air around your tumbling clothes. The gas valve coil is a part of the solenoid valve. Electricity passed through the coils causes the gas valve to open and close so that gas can flow through to the dryer’s gas burner. When the valve coils fail, the valve will not open up, and the dryer will not heat properly. Your dryer will not dry your clothes. Let’s get on to the repair of our Gas Dryer Valve Coils.
