I started to repair this and got busy and ended up calling a repair service -- that was the first time. They repaired it for over $200 and said the cause was bad venting. I fixed the vent before using the fixed dryer but it blew again. So I ordered these parts and replaced them myself for a lot of savings. However, the dryer still overheated. Through lots of testing I found the root cause the repairman missed: The heating element had gotten so hot that the assembly holding it warped, hitting the element and shorting it. So a new element is on order. I still needed the parts I ordered here but the overall repair ended up more complicated and expensive. I was disappointed a paid repair person left without further diagnosis. If he had unplugged the vent and checked the heat on the exhaust vent (as I ended up doing) it would have been obvious more than a new thermal fuse/thermistor was necessary. Instead I wasted over $200 on his visit. So my advice is if you're at all handy, repair this yourself. The dryer has a service manual inside the front toe board that walks you through most diagnostics and tests. However, it took a little more than that for me to discover the heating element problem. This was a very dangerous situation that could have easily led to a fire, yet not found by a trained technician!
