I have some experience with using a volt ohm meter and was able to check for continuity to make my best guess at what parts I would need for a sucessful repair. That and using the percentage of parts most commonly used for this repair as shown on the partselect site, I suspected the deforst thermostat and/or the compressor start device or overload was the problem. I started by taking the back panel off inside the freezer via the two screws at the top center. That gave me access to the fan and defrost thermostat. The fan was running which was good so I suspected the thermostat which is clipped onto one of the copper refrigerant tubes in the top right hand corner of the freezer. Per the instructions on the partselect sight, I performed the continuity test and confirmed that the defrost therostat was good. I replaced the back panel in the freezer and then moved my attention to the compressor strat device and overload which are mounted to the compressor. I ordered both the start device and the overload which are two separate parts. I was going to replace both even if one was bad because of the age of the unit. Therefore, I did not need to test for either part being bad I just put the two new parts in so I did not have to get down there again. Access to the compressor start device and overload requires you to remove the cardboard back pnel on the bottom rear of the unit. That gives you access to the compressor cooling fan and the compressor. With the unit plugged in and keeping you hands away from the unit, you can check to see that the cooling fan is running. If it is not, that component may have cause the compressor to over heat thusly damaging the start device and/or causing the overload to trip out or also become damaged. My fan was running and the compressor was cool to the touch so I suspected either the start device and/or the overload. To get at these to components, you will see a heavy plastic cover on the left end of the compressor toward the fan. UNPLUG the unit if you have not done so already. There is a diagram molded onto the face of the cover which shows you how to use a flat screw driver to pry the top of the box upward and then rotate it off the compressor. It depicts the box roation as clockwise via a curved arrow at the bottom of the diagram. It indicates that the box should be rotated upward from the bottom. This is NOT correct, it must be rotated from the top backward (counterclockwise) in order to get it off. I found that I needed a medium length flat tipped screw driver to get the cover off. This was a problem as the room between the fan and the box was not ample to get the screw driver in. I have to unpluged the connector on the fan and removed the fan via three screws using a small ratched and socket. This provided enough space to get the cover off. At this point you now have total access to the overload on top and the start device below. They are plugged onto the three compressor pins so you only need to pull them off to your left to remove them. You MUST remover the start device on the bottom first as there are two tabs protruding downward from the overload that are in front of it and therefore you would not be able to get the overload off until you have removed the start device first. I swaped out these two components, replaced the cover and re-installed/connected the fan. Before I put the cardboard panel back on the unit, I plugged the unit in and the compressor fired up and the unit was running just fine. An hour later I checked the freezer and all was GOOD! I hope that this helps you DIYer's as I wish I had this info when I done my repair. Beats $500-600 for a new refrigerator/freezer. Keith
