The original refer, they ran 120 voltage up to the inside eyebrow board and they had some problems. The recall involved replacing the Rear control board and the inside eyebrow control board and the harness from the eyebrow to the control board. Once the recall was done ALL control wiring was dc voltage with no AC voltage. IF the refer does NOT operate on 120 and the inside AC light is inop, I would invest in a new control board as long as you have verified the control wire harness from the control board to the eyebrow is not broken or chewed up(rodents).

You can call Norcold IF you can read the serial number, and they will tell you if the recall has been done.
