Troubleshooting MaxxAir Vent Fan 4951KSC Not Opening

Question:

Hello, I have a MaxXAire MaxxFan model number 4951KSC in my Momentum 5th wheel. The vent lift will not open. I have trouble shot it and believe that the control board in the fan is the problem, please advice on the correct part number to replace the control board.

For your MaxxAir Vent Fan 4951KSC you'd need the replacement circuit board # MA10A21275K.

I will say that since your vent has a rain sensor there is a good chance that could be causing your issue. If that part malfunctions it won't allow the vent either, and since its quite a bit cheaper its a good think to try first. For a replacement sensor you'd need # MA34FR.
