Auto Shut Off Switch

The auto shut off switch is for dehumidifiers. If the water bucket is not attached properly the switch will ensure the compressor does not run.

Consider wearing gloves to protect your hands while performing this task. This is a genuine OEM part that comes straight from the manufacturer.

Humidistat Control

This is a humidistat control for a dehumidifier. The humidistat on your dehumidifier responds to the humidity in the air to determine if the appliance should continue to dehumidify or shut off, based on the desired humidity level. This control needs to be replaced if the dehumidifier wont shut off when the desired humidity level is reached. This part is approximately 3.5 inches long and 1.5 inches wide. The part will be easy to replace, simply remove the front cover, remove the humidistat from the bracket, and remove the two push-on wire connectors. Reverse this process to reinstall the control. Be sure to disconnect power to the dehumidifier before completing this repair.
