Customer Questions and Answers for Dryer Gas Valve With Coils by Whirlpool

Mark, We're taking for granted you're discussing the burner flame cooling down and shutting off, not the dryer itself ? Presumably you don't have an issue with the gas supply to the dryer. You should have 3.0 to 4.0 WCI constant at the wall connection/shut off. Your next check should be to check the burn time, and dryer exhaust temperature, with the dryer vent disconnected. That should be an avrage of 155 dgrs, and the burner flame should be on for approximately 60 seconds, with no load in the dryer. A clogged or restricted exhaust pipe or hood,or lint build up in the blower housing(under the lint filter) will cause the dryer to cycle the hi limit switch and shut the burner down early. If the burner still cycles to quick, with the vent off, then it's time to check or replace the cycling thermostat or hi limit switch. Thanks
