Troubleshooting MaxxFan Vent Working with Remote But Not with Buttons On Fan

Expert Reply:

I reached out to my contact at MaxxAir and he said if the remote on your 12V Fan is working fine to operate the unit but the buttons on the fan itself don't work it very well be a bad circuit board. The Replacement Printed Circuit Board # MA10A21275K that you were looking at is the correct part as long as you have the # MA00-04500K, # MA00-07000K, or # MA00-07500K model fan.

He did also say that it could just be the actual keypad on the fan too. You might just inspect the key pad to make sure you don't see any physical damage around the buttons or signs that water may have crept inside. There unfortunately isn't a separate replacement part for this component available.
