Since your MaxxFan 4500k has buttons that are no longer working properly, and also has an issue with the motor, you will need a replacement:

- MaxxFan Plus Roof Vent w/ 12V Fan, Thermostat, and Remote # MA00-04500K

It is possible that the Replacement Printed Circuit Board # MA10A21275K with Replacement 12-Volt Variable Speed Fan Motor # MA10-20968 can remedy the issue, but there's no guarantee of that and the cost of these parts is going to be nearing a replacement, so the best thing I can recommend is a new fan.
