It sounds like your MaxxFan Plus Roof Vent, part # MA00-04500K, is having some issues with functioning.

A common problem with these vents is the wiring to the circuit board. Check those wires (specifically the power wire) to see if anything is fried. Pay special attention to the board itself.

If any of the wires are frayed or torched, replace them.

If you notice any damage to the circuit board, we have a replacement here, part # MA10A04751KS. It's a very easy install and could well be the solution to your problem. I've linked to a video review of this board for your reference.
