rooftop air

I have a 96 tioga montara class c. The ac unit has an issue I've diagnosed but I can't find the replacement part. It needs a new circuit board that has the compressor relay on it. The info printed on the board is" RVRB 7330A321". I have no idea of the manufacturer of the roof top ac. The badging is long since gone. Is there a data plate located somewhere on these units?

  • If you still have trouble finding the correct part you could contact http://www.corecentricsolutions.com, a company that rebuilds electronic boards to original manf. specs. Used them many times in the home appliance repair industry.
  • Part number 8330-3851 board, box and freeze sensor. Plug and play replacement.
  • I bought a new board once but cannot remember the type or circumstances.

    i do remember talking to a guy at PPL who knew the answer and specs on the board i was looking at and came up with the exact same replacement.
  • You have a COLEMAN, now called Airxcel. You will need to call them to see if the part is still available. Doug
