Dryer seems to run fine but does not get hot. (72882 series)

The cause of a gas dryer not heating can be many things. You need to diagnose the problem starting at the gas valve from the wall all the way through the dryer to the burner. Is the gas on? You may remove the flexline and check for gas. Reattach the flexline and see if the igniter is firing. It could be a faulty igniter. there are temprature limit switches that check if the dryer is overheating, if they get too hot, the dryer turns off the burner. switches are about the size of a quarter and there are usually two or more. One is a lower limit and the other is an upper limit switch The switches go bad after a while because they heat and cool many times over their lifetime. The way to check if it is a limit switch is to remove it from the circut and bypass it temporarily to see if the burner fires. If it is not a limit switch, it could be the gas valve. The valve is the brains and costs about $100 generally. Sometimes the valve can stick and believe it or not a good wack can unstick it.
Good luck....
