This fridge has a history of issues. In the past, it has always been the inverter board that was overheated or fried. It’s gotten to where I keep an extra board on hand, just in case. This time it’s a little different. The fridge side is holding steady at 53 degrees. The freezer is holding steady at 27. (The fridge is set at 40, and the freezer at 4.). I can see that the compressor fan is blowing, and I can hear and feel that the compressor is running. Since it’s the one trick I know, the first thing I tried was replacing the inverter board. The new board has been in for hours now, and no change. While replacing the inverter board, I noticed that there was a good bit of water under the compressor. I’ve never noticed that before. Looking online, that sounds normal, but it’s new to me. I sponged it up, and didn’t see more accumulate. After the new board didn’t have any effect, I pull out the multimeter and did some tests. The control line to the inverter board is at 11.8V. When I disconnect the control line, the compressor stops running. When I plug it back in, the compressor starts running again. I measured the resistance across the posts on the compressor. All three combinations come up at 7.8 Ohms. Everything seems to be working, except for the part where it’s not. Any suggestions?
Hey Daniel. Sounds like your sealed system may be working ok, as well as most other components. If the seals on the doors were bad, the system might be working fine, but the temperature in the frig and freezer would be elevated because the bad seal is allowing the cool air to escape. I say this primarily to show an example on this point. Likewise, if the evaporator has an icy buildup it will create an insufficient cooling condition. This would result from something going wrong with the defrost cycle. Check the evaporator. If you find an icy buildup the problem could be with a thermistor, bi-metal thermostat, defrost heater, or the main control board. If the evaporator looks fine, you may want someone qualified to check to see if the refrigerant charge in the sealed system is within spec. Hope this helps. Good Luck.
Sounds like you replaced the Board many times. You may have pulled the thermostat wire some from the original position, if not then the thermostat Probe for the fridge side is bad. As for the water, it will happen after a defrost cycle, that is normal.
Ended up calling in a pro, and he found that the evaporator coil was frozen over. Thawed it out, and it’s worked since.
