The compressor would not run.
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.

Compressor was short cycling
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.

This dehumidifier is the best we have ever had but the water reservoir container split and the float broke off.
Never dreaming I could find a replacement, I went searching on the internet anyway and found the model which had been discontinued however the container and float were still available. It took two minutes to put the new float in and the reservoir container on the unit. It works great!!!
