I have a whirlpool gas dryer. My dryer all of a sudden would not heat up. I diagnosed the problem and discovered that it would light (using the peep hole in the front) when the dryer was cold, but once warm, the flame would go out. I bought a cheap multimeter and tested all the themostats on the back of the unit after removing the back panel. All the thermomstats checked out except the cycling thermostat which should no signal through one of the connections (purple wires). I ordered a new thermo and replaced the old one but it didn't fix the problem. Seems that there isn't a current between the purple connections.... Since the flame did light when the unit was cold I figured it wasn't the ignitor so it was either the flame sensor or the coils. I took the top and front panels off (alot easier than I thought; see videos) and checked the flame sensor with my multimeter. It was fine. Only thing left was the coils, so I ordered a set. IF YOU NEED COILS, SAVE YOURSELF MONEY AND ORDER THE PAIR. YOU GET BOTH COILS FOR < HALF THE PRICE IF ORDERING INDIVIDUALLY. Replacing the coils was rather easy. You will need to prop up the drum with something to keep it from impeding your screwdriver. A stubby philips really helped here. Also, since the gas valves are closed when there is no power, there is no need to disconnect the gas line and fuss about a gas leak (This really saved time). Once the two screws for the coil plate were out of the way, the coils simply slide off the valves and unplug easily. NOTE: Make sure you line up the one new coil with plate when you put it back together. It has a little tab that fits into the plate. All-in-all it took about 30-60 minutes to do. If I were to do it again it would probably take 15 minutes. Pretty easy job for a do-it-yourselfer with only basic tools.
