Sg7800 maytag dryer stopped giving heat - Dryers

Sounds like burner not igniting. On front of dryer in the lower right there should be a gas valve/burner access panel. Usually you just have to pry out at bottom of panel & swing out and up to remove. This gives you access to valve coils and igniter. With panel removed set timer for heated dry and start dryer, observing first the igniter which should glow bright orange-red, then after a couple seconds you should hear a "Click" which is gas valve opening and a blue flame ignites for heat. If no glow is seen after a few seconds or at least a minute, igniter is bad, if it does glow and no click is heard from the gas valve, the coils (electro magnets) on the valve are bad, or the "Flame present" sensor is bad. Chances are it's either the coils or igniter.Try this on all heat settings, if you get heat at only one setting it might be in timer contacts, but not common. Again you can repair/replace both the igniter (usually just plugs into a receptical) and the coils (2 donut looking objects on the gas valve, replace both.) Access door may be on back if not on front, but normally their on lower right of front.
