Question:

Hello so recently our maxxair 7500k deluxe fan has been making the awful beeping noise with the green light of death after trying to operate it. I believe when we were plugged into shore power we were receiving over 13.6V at the time and didnt know that we could fry the circuit bord if we kept trying to operate it at such a high voltage. I guess now im wondering is the circuit noardfried from what I could tell you through this and will we have to replace it?

I suggest pulling the 12 volt DC fuse and let it sit for 15-20 minutes to try and hard reset on the MaxxFan Deluxe Roof Vent w/ 12V Fan, Thermostat, and Remote - Powered Lift - 10 Speed - Smoke # MA00-07500K.

While you are waiting remove the trim and check all the wires and connections for damage like corrosion, shorts or overheating.

Also remove the circuit board and check it for damage too. When putting everything back in and reconnecting circuits make sure the connections are secure and not loose.

Once you have everything back together, and you are sure you have a steady and good voltage, try to operate the fan again, if it does not work then you could have a faulty circuit board and can replace it with the Replacement Printed Circuit Board for MaxxAir Powered Lift RV Roof Vents w/ Reversible Fan # MA10A21275K.
