Abstract
An illustrative example method of maintaining an elevator drive includes determining whether a humidity condition near the elevator drive is outside a desired range. When the humidity condition is outside the desired range and the elevator drive is idle, reactive power is provided to at least one component of the elevator drive to increase a temperature of the at least one component without using the elevator drive to operate an associated elevator system.
