It sounds like your MaxxFan may need a new circuit board. Typically, when customers had similar issues they were able to replace the circuit board and their fan return back to normal operation. You can use Replacement Printed Circuit Board # MA10A21276K if you have MA00-04000K, MA00-05100K, or MA00-06200K. You can use Replacement Printed Circuit Board and Switch # MA10-04301k-v16 if you have MA00A04301K, 4201KW, 4251KW, or 4401KW. You will more than likely need the first option, # MA10A21276K.

I do not see that MaxxAir made a MaxxFan 4751K. They only had the 4751KS which is what the Circuit Board #MA10A04751KS you are looking at fits. If your tag does not have the S it could be it simply wore off and you have the 4751KS.
