Part #5303306080
If the bucket is full indicator on your dehumidifier is on, but the bucket is empty, or your dehumidifier is overflowing, you may have a problem with the float. This device is located near the bucket and moves up as the water level in the bucket rises. The float will trip the water level switch when the bucket is full. This is a safety device to prevent the unit from overflowing. When the switch is tripped, power to the compressor and fan motor circuits is disrupted until the bucket is emptied. Make sure that the float assembly can move or pivot freely so that it can trigger the level switch when the bucket is full. If the assembly is warped or damaged it should be replaced.

Humidistat Control
Part #5303296823
This is a humidistat control for a dehumidifier.

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.

If your air conditioner is not blowing cold air or fails to turn on, a faulty motor may be the cause. Installation should be performed with the power disconnected to ensure safety. This OEM part is engineered for a precise fit and reliable operation, but users should verify compatibility with their specific model before installation due to variations in size and design.

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!

The repair was just putting the float into the inside of the tank itself and then, inserting the two pins (left and right) into each slot so the float operates up and down freely.
