Great to hear about the repair and service.
I had a problem with my Maxxair Fan only working on the high setting. I called Maxxair hoping they would replace under warranty since the original owner had the problem since just after new. Unfortunately, the gentleman I spoke with wouldn't cover it. I was a little disappointed since the original owner had dealt with them trying to diagnose / fix the problem during warranty and Maxxair sending two different wall switches to no avail. I just wanted it fixed so I ordered the circuit board (accessed from inside the RV) for around $45 (shipping included) and replaced it yesterday. The fan is now operating properly. I believe my model is 4700K?
As for the repair / install, it is not just plug and play as the tech led me to believe. You'll have to strip a couple of wires and possibly reuse the existing sensor wire (new board has the sensor plug relocated on the board and the new wire is not long enough to reach)
. Fortunately, my dad (electrician) is camping next door with us this week and he and I made the repair in about 30 minutes. Just be certain not to touch to two power wires (white / black) as you'll kick the 15 amp fuse for the bathroom. Ask me how I know.
Message me with any questions.
