My clothes dryer, a Kirkland Signature by Whirlpool, is rotating but not heating

There are several things to look for, but they are simple with an ohm meter. As long as you can use a meter you can know very quickly, just make sure you clean out all air passages in the dryer. That means taking it totally apart and not skipping anything. Most people cannot grasp the importance of doing this and wind up taking a dryer apart several times before they get it right and wash out the parts, as well. Here are the Whirlpool manuals: http://dl.dropbox.com/u/8010163/Whirlpool%20Dryers.zip
If you have any problems let us know. Most likely, a safety has burned in two from the lint deposits causing it to overheat. It's like concrete and you have to scrape it out then wash out the parts; vacuum out motor.
