My contact at MaxxAir advised that there are three potential causes for the beep and no fan motion you're experiencing with your MaxxFan Trailer Roof Vent # MA00-04000K.
One potential cause is that the unit was wired with incorrect polarity. Make sure the white wire is grounded and the black wire is connected to your 12V power source (of at least 5-amps). Another possible reason for the malfunction is low incoming voltage. Use a voltmeter like # PT89ZR to make sure your battery is delivering the required voltage (no less than 11-volts).
The other possibility is that the circuit board in the fan is damaged, so try the above two checks to first eliminate those possibilities.

Hello... my MaxxAir fan still works, but while it’s spinning at a high rate it stopped exchanging much air... like even at 100%. What could be causing this?

My fan works but it no longer closes. It was gradual, there were times we could not get it open.
