How to Troubleshoot & Replace Ge AP2042691 / WE4X600 Thermostat

Replaced the thermostat that controlled the drying temperature. 

Thanks to the quick shipping and quality parts from Appliance Parts Pros, I was able to replace the faulty cycling thermostat in my dryer. The old thermostat failed catastrophically, igniting a lint ball and nearly burning down my house. Thankfully, our we have good smoke detectors and were able to stop the dryer and clear things out before the situation worsened. The new parts arrived quickly and the install was simple. I also changed the high-limit thermostat. It looked and tested fine, but failed to shut off the heating element when the cycling thermostat changed. It's cheap insurance against another incident. 

Ordered 3 thermostats as suggested by Appliance Parts Pros. 

I first located the thermostats and removed them. I connected an ohm meter to the terminals and placed them, one at a time, in a cast iron pan on the stove. The cut-off temperatures were printed on the label on the backs of the thermostats. (1 @ 145 degrees and the other @ 258 degrees). I slowly warmed up the pan and watched a thermometer as the temperature rose. The ohm meter may have not been necessary since I could hear the thermostat click when it activated. I took a half dozen tests and came to an average reading. The lower rated activated around 139 degrees. The higher temperature rated thermostat didn't activate to well above 310 degrees. That was the bad one. Since I had ordered both, I went ahead and replaced both of them. 

Ordered new thermostats and they arrived in two days with standard shipping. Awesome. The parts were exact and work great. Very impressed with the price and the delivery. Great experience. 

My old dryer (about 25 years) wasn't heating. So I looked at the heating coils. One was broken so I replaced the heating assembly. Still didn't heat, but I did notice if I turned the timer to a very specific spot the coils would glow for a short time. I found * appliancepartspros.com they had parts to pick from. I had to do some research and cross reference part numbers which were a little tricky considering the age of the dryer ( GE ) 5 cycle large capacity. I then replaced the timer and the thermostat to join the heater unit I had already installed. I can't stress enough to do your due diligence regarding replacement parts. It can help a lot to remove them and have them with you for visual comparison. My investment of a couple of hours of my labor and approx. $ 325 was FAR cheaper than the cheapest crummy import replacement at the local Big Box store. You can do this simple repair! Thanks, Appliancepartspros.com !! 

Checked connections found bad thermostat. Replaced thermostat. 

Watched video that was available and unplugged dryer and followed steps i seen and everthing went very easy til i put in thermostat and the holes were too big in thermostat for screw to hold in place. i rotated thermostat and marked it and drilled new smaller holes beside old ones. dryer works perfect for around 30 dollars shipping and all.
