So ... I'm out of town a few days and when getting back home decided to catch up on doing some laundry.
After the first load of wash finshed it went into the dryer while the second load was washing ... I decided to get caught up on things around here on the forum.
I heard the washer finish and went down to check the clothes in the dryer. The cycle on the dryer had ended but the clothes were still damp .... not a big deal right?
Turn on the dryer for a few minutes longer ... it didn't start up ... only the sound of the timer running.... hmmm.
Murphy's law.... washer full of wet clothes and a dryer full of damp clothes.
Well .... took off the bottom cover and sure enough the belt for the drum broke.
Lucky it wasn't too late in the evening or a Sunday ... drove down to the appliance parts shop picked up a new belt.
Took the dryer apart and while there got out the shop vac and cleaned up all the lint bunnies .... man that stuff gets everywhere.
Now the reason the dryer wouldn't run .... aside from the obvious broken belt .... is the belt tensioner presses on a safety cutout switch. It's function is to disable the gas burner in this case .... or the electric elements from turning on ..... causing a potential hazard.
As you can see the tensioner is spring loaded so when the belt breaks the spring pulls the tensioner back ( to the left) .... opens the contacts on the switch ( yellow connectors on white wires ) and disables the dryer .
All said ... two hours .... including driving to get the belt and vacuuming out the lint bunnies .... and $12 for the belt.
Hopefully this helps.
