This refrigerator doesn't just have a normal relay. It seems to be integrated with a gray box on the side of the compressor called an inverter which costs about $200 (see attachment). I had a Frigidaire refer in my garage with a bad relay and it kept trying to kick in the compressor, but never would. It would make several attempts. I put a "hard start" relay on it, and it now works fine. The refrigerator I'm talking about now is in my house and the compressor kicks on when I first plug it in, but after it shuts off, it doesn't try to kick on again. That's why I'm wondering if the refrigerator "calling" for coolness? A posting I read on another site said that a flashing 2 on another Frigidaire model refrigerator indicated a freezer thermistor was stuck open. Not sure I even have one of those on my refer.
