I knew that the dryer needed a new belt and since the dryer was also failing to dry the clothes in one cycle, I decided to replace the three thermostats, figuring that I might as well do all three if I'm going to open up the dryer. I downloaded a schematic of the dryer from the Whirlpool web site, which helped me to order the right parts and see how I would be able to make the repairs. Once I figured out how to get to the drum for the belt replacement, installation was quite easy.

First step was to unplug the dryer, remove the vent hose and remove the back panel with a nut driver. Once the back panel was removed, it was easy to see all three sensors. The heating element unit was easy to remove - two screws. This made it easier to replace the sensor. Each sensor was shaped differently, making it easier to decide what went where. This normally would not have been a problem, but the part numbers have changed for this dryer. I could have also cross referenced the parts by using the partselect.com web site.

To access the dryer drum, I had to remove two screws on the back of the dryer that are located in two tabs that hold the control panel to the dryer cabinet. Once removed, it was easy to lift the top of the cabinet and swing it up and against a nearby wall for support while I replaced the belt.
I removed the old belt from the motor pulley, and then just removed the whole drum. I placed the new belt around the drum, placed the drum back in position. With my wife supporting the drum, it was easy to bring the belt through a guide and slip over the motor pulley. Then, I rotated the drum manually to make sure the belt wasn't twisted.

After ten minutes of putting everything back together, it was time to plug in the dryer and test it. I did it without a load first and checked the vent for hot air. After that, we did a couple of loads...one on high and one on perma press, and when the cycle was over, the clothes were dry!

Delivery time from PartSelect was super fast! Prices are excellent, and I really appreciate such a helpful web site. Anyone with a small amount of mechanical ability and "do it yourself" experience can save $$$ by fixing it yourself. Having someone service this dryer would have cost me more just to replace the belt.....let alone the added insurance of replacing the sensors. And, I learned that if the heating element should fail, replacing it would be a snap, and would start with a visit toe partselect.com!
