This fixed my commercial grade dehumidifier. My dehumidifier control circuit stopped working. It would only run in continuous operation mode. That ran up the electric bill. The dehumidifier was made by a smaller HVAC company and there was not much information about parts or circuits out there. They did not have a large customer support geared towards consumer repair of their equipment. I searched for replacement humidity sensors suing the parts numbers on the failed unit and found nothing. I started comparing images and found the circuit layout pictures of this sensor matched the layout of the failed sensor, and took a chance. It is an exact replacement. This seems to be an industrial standard 3 wire humidity sensor found in OEM packaged systems.

Maybe my fault for thinking it was a 'fit' for my Maytag M7DH4582A dehumidifier. I plugged it in; the connector matched perfectly but the device sensor got real hot and did not work.
