Hi
My freezer is not cooling past 27 degrees. Haven't begun any troubleshooting, just finished clean up. How do I enter diagnostic mode on these units? Is there a manual that shows what these codes refer to?
Any input is greatly appreciated.

Remove the freezer back panel and describe the frost pattern, total heavy frost, or partial.

Is that the panel inside of the freezer?

Alright also found compressor not hot at all. Seems to not be kicking in. Have the run capacitor in hand to test. Will get back.
Well capacitor was charging, thermal switch, it was still intact and conducting, overload relay was closed. All good there.
Not getting 120v at compressor. I get it on the wires leaving the main board, but not after it travels up over the back of the compressor and into the sealed area of the unit and back down to the compressor front side.
Where does that wire harness travel to or is it run that way to keep it away from the compressor?
BTW ~ Let's go ahead and disregard the 27 degree statement at the beginning of the topic. It was just the contents of the freezer keeping it at that temp.

Pull the motherboard, probably a bad solder joint in the back.

Found a burned area on the back of the motherboard. It is under the biggest relay on the board that is connected to the line coming in to the board. The solder is completely gone at one leg of the relay. I don't know if something caused this or if a cold solder joint could have caused high current at that spot. I sure don't want to replace this board and it happens again. It seemed that everything was working except for the compressor. I hope I have enough time once it is all back together to measure the current draw to the compressor. Has anyone ran into this and replaced the board and all was okay?

The solder joint was too thin and acted as a fuse, re-solder usually fixes it.

It's been running all night!
I had to extend the solder out to the trace because the area around the pin leg was missing.
Thanks Rich for the assistance.
Oh, and one more thing, do you know where on the motherboard does the contact on the filter housing come in? I need to bypass that. That's been a PITA ever since we got that unit. I have my own filter installed in line and have used the water filter bypass plug but sometimes the plug cracks under all that stress. I could trace it out if not.

Pull the service sheet behind the control panel in the fridg. will show the wiring diagram.
