KitchenAid Dryer Repair
KitchenAid Gas Dryer
Gas dryer tumbles with no heat
Remove the front on the lower panel of the dryer and start the unit up. Set it up to heat, watch the gas valve assembly, and you should see after about thirty seconds a bright orange glow, which should be the igniter glowing. After the igniter gets up to the right temperature, the flame sensor will make a click sound and the gas should turn on.
If the igniter is glowing, and it never turns off, then it is most likely the flame sensor.
If it glows and you hear a click and the igniter turns off and there is no gas, then wait another two or three minutes. If you see it glow and you get another click and the gas doesn't turn on again, then it is probably solenoid coils on the gas valve that have failed.
Solenoid coils are not that difficult to fix for a do-it-yourselfer and are a fairly inexpensive repair.
If there is no glow whatsoever, make sure that the igniter is not cracked or broken. Check it with a multimeter (part #DM10T) for continuity. One of these possibilities should take care of your KitchenAid dryer repair.
