Troubleshooting MaxxFan Plus Roof Vent

Question:

I had it on the auto temp setting. Then drove off and it started beeping. Now nothing works, but the green light stays on, but the van will not respond at all. Thanks

According to the manufacturer's instructions three beeps and a green light on the MaxxFan Plus Roof Vent # MA00-04000K indicates you have entered Auto Mode so that all seems normal. However, if the light is on but the fan has stopped working that is most likely a sign that the circuit board has failed and needs to be replaced.

For MaxxAir model 4000K you'd want to use Replacement Printed Circuit Board for MaxxAir Manual Lift RV Roof Vents # MA10A21276K.
