Test Norcold Control Board
We have a Norcold 1200LRIM fridge. It stopped working on AC. The tech came out, saw that there was a brown burned spot on the board, and said it needed to be replaced. He did so, but that did not fix ...

If NOT working on AC, even if you have a burned spot on the board. I assume it was at the 120 element fuse area. You check for 120 at the Element fuse. Then you OHM out the 2- 120 elements.
1. If you have current to the board but NO power to the fuse, the board is probably bad.
2. If you have power to the fuse and Power at the 120 element terminals--the elements are bad (replace BOTH even if one is still good).
3. You have to have the board installed for a check out.
4. 120 diag is SIMPLE if you know what you are doing.
5. If he determines that the 120 elemnts (1 or both) are bad, he replaced a board for no reason. Brown spots on the fuse area of a Norcold board are not uncommon for a good working board. Doug
