This is a Samsung made GE:
Power outage probably affected the power board instead of the main board. The power board converts Ac to DC and the DC voltage is sent to the mainboard. Your mainboard is probably not receiving DC voltage.
Your compressor receives its AC hot line directly from house current and receives a switched neutral from the board. The board has the neutral but it is currently not being switched and simply supplying raw neutral to the, compressor thus your compressor runs.
Test voltage to your power board. You should receive 120vac at cn1. If not, you have a wiring problem.
If 120vac found, as I suspect, test for 5vdc and 12vdc at CN2 on the power board. You should get 5vdc between the red and black wires and 12vdc between the yellow and black wires. If you don't have both voltages (which I also suspect) , replace power board and voila, Bob's your uncle.
If you do have proper voltages, then check to see if it is being sent to the mainboard at CN10...same as above, check the red to black for 5vac and yellow to black for 12vac. If you don't have it but have those voltages at the power board, then you have a bad connector between the boards.
Many parts houses erroneously call the board an Icemaker circuit board, so don't be alarmed it you see that when you click on the link. It's actually a rectifier (converts AC to DC voltages) and powers the mainboard. Maybe when the manufacturer said "rectifier" the dummy on the other end heard "icemaker" and subsequent dummies copied the description.
Part number: AP4327500
ps: I strongly encourage you to use a surge protector with a rating of at least 1000 joules on your fridge.
