Do a search of magnet and Norcold for directions for resetting. You should be able to figure out where the big wire on the recall box would go on the control poured where the blue wire is attached from the recall box. You have a 12 V problem not 120 V problem.
The failure rate of the recall box is huge and Norcold should replace it for free.
