Product review (5 stars): Easy & cheap fix
This relay replacement kit did exactly as advertised. If your refrigerator stops being cold, this is a very likely piece to replace. The directions were very easy to follow. You only need to look on the compressor for the model number, and this lets you know which pieces to use in this kit. Even a person with little to no skills could probably install this. All that is needed is a screwdriver. The entire process of removing the old relay and installing the new one took about an hour total. This also saves a lot of money compared to having a technician come out to look at your refrigerator. The price here was lower yet than several other appliance parts suppliers that I have dealt with before. I would definitely recommend using this kit.

For reference: My refrigerator slowly started getting warmer inside. I first noticed it in the freezer when the ice in the dispenser started melting. I had also noticed a periodic clicking noise that was not normal. This was the failed compressor relay trying to operate, but not being able to turn on the compressor. After removing the relay, I shook it and heard all the faulty parts rattling around. After disassembly, the inside of the relay was melted and charred. If your relay has not failed this badly, you can use a multimeter to test the resistance of the relay. Search for "refrigerator troubleshooting" online if you need to look into further. There are several sites that can help you figure out the issue.
