Replacement Circuit Board For A MaxxAir MaxxFan In A 2021 Grand Design Solitude 3540 5th Wheel

Question

Question:

Hello, my name is. I have a 2021 Grand design Solitude 3540. I have a maxx air, 4 speed with a rain sensor in the kitchen. The airxcel hanging under the thermostat has 4 buttons: 4 speed fan, vent open, fan off and vent close. Im searching for a motherboard for replacement. The fan runs but I have to remove fuse to stop the fan. The vent operation doesnt work so i turn the knb to open and close it. So I need a replacement motherboard. Thank you for your time.

Since multiple MaxxAir Fans have the same features that you listed it's honestly best to first determine the exact model number you have before purchasing anything and end up not having it be compatible. I've listed below all the available circuit boards for the each model, if you have a tag on the vent listing the model number then we can identify the correct replacement. If not, you'll need to pull the circuit board and find the sticker on it that lists the model number. Once I have either the model number of the vent or model number of the circuit board I can find the correct replacement for you.
