My Kenmore Elite Smartheat Quiet Pack 9 dryer does not heat up.
The drum turns all lights and controls work. Lint trap is clean Where should I start troubleshooting?

Hi Jake and welcome, you'll need to start with a volt/ohm meter to check the safeties, do you own one and know how to use it?

These driers will do that when the lint builds up like concrete on the inside of the air ducts. They blow the main safety to keep it from burning the house down. Halfway cleaning it will not work. If the fuse blows you need to totally tear it down and scrape out and wash all of the parts except the motor, which you vacuum out. You can go to YouTube to see videos on how to take it apart, but do a very good job or it will fail again quickly. I would get a new belt and change it while you have it apart and get some white lithium grease and grease any bearings you find. You need to clean out a drier every two years, at least, according to the manual. You just unplug the wires from the sensors and remove ductwork that they are attached on and clean the entire thing with soap and water. Make sure you go all through the dryer and get all parts like the blower fan and housing, vacuum out motor well and clean exhaust. Mark all wires you unplug so you know where they go. This is an easier job than you would think. Make sure to clean around all of the sensors, too, because when they cannot sense the dryer will not work, plus the burning lint deposits will burn down your house. The blown safety is like a fuse and located near the elements. You will need a meter to find the safety that is blown . Replace the belt which you can get the same place that sells a new safety.

Go to Home Depot, Lowe's, or Radio Shack and get a good digital multimeter because without a meter you are really working in the dark and cannot repair it. Try to get one with auto-protection of the ohm meter circuitry instead of a fused protection. When you are using it on "ohms" always have the power off and test it first with the volt meter to make sure there is no residual stored power in a capacitor. Short out capacitors before testing them, always. They can kill you even with the power off. Once you have it all clean and replaced the belt and blown fuse you make sure to grease all bearings with white lithium grease, you will have a new dryer.
