We replaced the main circuit board and the LED started to work and the condenser fan worked, but all we had were relay clicking sounds, but no cooling. The compressor had become so hot trying to work when the main circuit board was amiss, that it had popped the over temperature sensor on its side. As some one point out, if you remove the PTC+OLP assembly with the capacitor on it, and shake it, you will hear a rattle inside---and that is bad. We ordered a second round of parts from AppliancePartsPros---the PTC+OLP Asm and the Run Capacitor, popped them on, and all is well! But two sub notes; the spring that holds the PTC+OLP unit on with the Capacitor was too big, and we had to bend it down to fit. Also, when the frig started back up, it required so much cooling to get to down to temperature that the compressor got strained and hot. Suggest having NO food in the frig and the ice maker off and cool it down in stages----such as 10f for freezer and 47 for frig, then keep nudging it down after it turns off at the set point and rests for a half an hour or hour. Or the other way of doing it is to leave the bottom panel off and blast the entire rear of the compressor and condenser with a large external fan for maximum cooling until it makes it all the way down to temperature and turns off at the set point. AppliancePartsPros was great on getting the parts to us on time, and the comments from others help guide us and encourage us to stay the course. We ended up spending perhaps 10% of what it would have cost us to replace the frig fixing it---a lot better for the pocket book and more ecological as well.
