2006 TT 20BH Heater circuit replaced

[BOVAIR]

I asked for help troubleshooting my heater unit in my 2006 featherlite 20BH. The heater unit quit working. I finally took the couch out to get to the heater unit and took it apart and cleaned all the dust stuck to the blower fan and took the circuit board out. It was covered in a thick wet dust. Took the board to a camping world dealership and they tested the circuit board which was bad. So I ordered a new on on EBAY for only $79.00, saved $59.00 buying it online. Hooked it up and tested the gas line for leaks and the heater blower started blowing and it fired right up. Heater now is working great, took time to reinforce the couch frame to it no longer dips in the center. just added a frame with cross supports made out of 1x2 inch boards, less than 20lbs. So thanks all who gave advice to help me figure out how to fix this problem.
