Do-It-Yourself Story

I disassembled/reassembled the dryer according to the ApplianceParts Youtube video. With my limited electrical knowledge (just enough to be dangerous) I initially figured it was a problem with the heating unit, sensor(s), or the control board. After diagnosing the problem (bad thermistor), I had to order the parts and was able to repair and reassemble the dryer several days later. After removing the drum, I cleaned all the dust etc. out of the inside (it gets dirty in there!) and inspected, cleaned and tested the heating element. It tested around two ohms (red/yellow and red/blue). I tested both thermostat units screwed into the heater element housing and they both tested at low ohms. Because It was relatively cheap, I opted to replace both so I didn't have to apply heat and see if they opened. Plus, after a good 5 years of operation it can't hurt! I checked the thermistor in the blower assembly and replaced it; it was bad (tested continuity). I tested the thermostat in the blower assembly and it tested at about 2 ohms. I would have replaced it, but it was not available on the ApplianceParts website. I reassembled the unit and replaced the belt on the drum (the old one was still good, but felt somewhat dry/not as flexible as new). The dryer now functions as it did before. As a side note, after resuming use of the dryer, I became concerned because after pressing the start button, the drum starts to turn, the dry light is flashing, the cooling light stays on and the timed dry light stays on. After looking at various forums, this appears to be normal operation. The project took approximately 4 hours for me because I thoroughly clean everything and try to inspect all of the parts and look for damaged components and wiring before I re-install. An experienced technician familiar with this model (and possessing needed spare parts) could have done it in under 30 minutes. All you need for this project is a Phillips head screwdriver, an ohmmeter and an external light source (headlamp, etc). A drill with a Phillips attachment will make disassembly much easier and a can of compressed air will help with cleaning the dust and crud out of the motor and blower assemblies. Taking pictures with the phone on your camera during disassembly of parts/wiring will make reassembly much easier as well. Overall, a fairly easy job.
