Over the last year the 'start' button has had to be held to 'start' the dryer, with a humming noise during the process. Eventually it hummed, stank, and wounldn't start.

Yanked the front panel, observed motor operation while my smoking hot wife started the unit. Our washer and dryer get beaten like rented mules with kid laundry. I tried this site, and decided to spend a little $$ on a replacement motor. I was impressed with the operator, she even asked what the symptoms were and helped to avoid wasting time and money.
The part arrived on time, and installed quickly. I am a hero in my wife's eyes, and that certainly carries weight.
Then again, I didn't have to dispose of the old dryer, pay for a new one, or haul the replacement upstairs.
Win-win!
