Kenmore 64112 dryer wont start when I hit the start button

Check house fuses or circuit breaker.
Pull 220V cord from wall outlet and inspect the gold prongs.
If you see any burnt areas on the prongs the outlet is bad.

If the unit makes no noise when you press the start button check the dryer door switch and make sure it clicks when depressed.
Sometimes the door switch arm can break off so when the door closes
the door switch cannot be activated.

If you hear a growl noise when you press the start button 2 things...
1. The motor is bad and needs replacing.
2. An object fell down the lint trap and is preventing the motor from turning.

Also if the dryer vent has been plugged causing the dryer to over heat a saftey fuse may have blown and needs replacement.
