Frig would kick on and off until the code sy ce would show on the door. If I would hear it happening I would open the freezer door for about 30 sec. and close slowly and it would be fine. But if we miss it it would shut down. I ordered switch board and electrical control board.Electrical control board was easy putty knife was only tool needed took about 10 min.. The switch board only tool needed was a 1/4 inch wrench or socket.when you remove the tray under the frig. it is a tight fit but you do not have to jack up or tilt the frig to get it out. You unplug the cables and and the new switch board has new wires to adapt the new board. The only problem with the replacement is getting all the new wires back in the switch board tray this took me about 20-30 min. works great when I first plugged it in it took about 20 sec. to start a little scary but all is well.
