Repair & Advice
Board is in a metal housing right rear side underneath. Attached with 4 Phillips head screws. There is a diagonal brace on the rear corner that is removable with a 1/4" nut driver, flat blade screwdriver or 1/4" socket or wrench. First step, unplug the power cord! Board has 4 latching electrical plugs and 1 pigtail with a latching connector. The large one on the front outboard is AC power and compressor control, the others are sensors, 9V battery and display connections. Unplug or disconnect all then R&R the board, reconnect all plugs and plug the freezer in, it is also a good idea to replace the 9V battery while doing this, it is on the bottom grille right side.
