My fan spins but the lid won’t open. Is the lid motor probably the problem? (MaxxAir 10-20270 Roof Vent Lift Motor For MaxxFan 4500K-8951K)

Yes, the lift motor is one possible cause if the fan operates normally but the vent lid will not open. However, the lid operator mechanism can cause the same symptom. If the lid can be operated manually and the mechanism moves freely, the lift motor is likely the problem. If the manual lift is difficult to turn or feels jammed, the operator mechanism should also be inspected.
