Question about Whirlpool AD40USR Dehumidifier
Unit is two years old. Fan runs good but compressor tries to start and only runs for a second or two.
The over-current relay is tripping out the compressor motor to prevent excessive current through motor windings. To prove this theory, open unit, find motor wires, disconnect wires from unit, and apply 120VAC to motor using external circuit-breaker source. Run 2 minutes max. If motor continuously turns, then relay is failing. Find it by tracing wires back to source and finding a small rectangular item. If motor again quits after 2 seconds, then this motor has an internal over-current self-resetting fuse that may be doing its job of preventing an electrical overload from a dead (shorted) motor.
