Question:

My positive and negative are correct. My volts are not below 11 Periodically my green light flashes and the fan shuts off for no reason. What do I need to do to correct this issue?

I'll start off by saying that typically the flashing green lights on your MaxxFan # MA00-04000K means that there is some sort of voltage issue and even though when you tested you're getting what seems to be proper voltage, I would guess there is a short on the circuit that is causing the problem.

I would recommend checking to make sure that the ground is properly attached to an area of the coach that is free from dirt, debris and corrosion. This would also be a good time to make sure that the connection with the 12v power wire is good and not going in and out because of a poor connection.

If both of these check out, it's possible that your circuit board is going bad. To replace the circuit board on your MaxxFan # MA00-04000K you can use part # MA10A21276K.
