Troubleshooting Maxxair Model 4951 KS With Cover Problems


My Maxxair model 4951 KS cover will start to open and then close. Then sometimes it will open with no problem. The cover is not sticking or binding. Could this be a faulty rain sensor board? If so, what is my replacement part number? Thank you

This sounds like a problem with the circuit board more than a rain sensor.

I recommend, if you have not already, removing the vent from all power for 1-15 minutes. Let it have a hard reset, use this time to give it a good cleaning if needed. Wipe off the sensor and check to make sure everything looks in good working order.

After you plug it back in if it is still acting a fool I recommend getting a new circuit board. It will be the Replacement Printed Circuit Board for MaxxAir MaxxFan Plus Roof Vents # MA10A04751KS.

And for future use if you do ever have a rain sensor issue you can get them here too. Replacement Rain Sensor for MaxxAir RV or Trailer Roof Vent Fans # MA34FR
