I removed the cover, used a multimeter to test the compressor circuit, and found the compressor start relay to be defective. Ordered a new one and installed it when it arrived.
Removed the cowling with a square drive screw driver, removed the spring clip from the cover of the compressor controls with a screw driver, pulled off the old compressor start relay and replaced it with the new part. Since other problems could have caused the compressor to short cycle this was a "replace the part and hope it would work" since that would be the most common reason and it was not a very expensive part.
Removed the front cover and then the humidistat from the bracket. Two push on wire connectors and then reversed. Very straightforward and excellent part matching. Given the prices for new dehumidifiers it was great to breathe life back into this unit which does its job well. Thanks for the easy to use web site and fast fast service!
