Most Frequent Causes for Dehumidifier not working

For the most accurate results, enter your model number.


Cause 1Bucket Switch

When the water bucket reaches its capacity, the bucket switch opens to shut off the dehumidifier. If the bucket switch fails while it is open, it will prevent the dehumidifier from running. To determine if the bucket switch is defective, use a multimeter to test it for continuity. If the bucket switch does not have continuity, replace it.

Parts
Cause 2Humidistat

The humidistat monitors the level of moisture in the air. When the moisture level is too high, the contacts in the humidistat close to allow the dehumidifier to run. If the humidistat contacts fail, the dehumidifier will not run. To determine if the humidistat is defective, use a multimeter to test it for continuity. If the humidistat does not have continuity, replace it.

Parts
Cause 3Control Board

The control board monitors the level of moisture in the air. When the moisture level is too high, the contacts in the humidistat close to allow the dehumidifier to run. If the control board is defective, the dehumidifier will not run.

Parts
Cause 4Humidity Sensor

The humidity sensor monitors the level of moisture in the air. When the moisture level is too high, the contacts in the humidity sensor close to allow the dehumidifier to run. If the humidity sensor is defective, the dehumidifier will not run.

Parts
Cause 5Compressor

The compressor is a pump which compresses the refrigerant and circulates the refrigerant through the evaporator and condenser coils. If the compressor is not working, the dehumidifier won’t cool. However, this isn’t usually the case. Before replacing the compressor, first check all of the more commonly defective components. If all of the other components are working properly, use a multimeter to test the compressor for continuity. If the compressor does not have continuity, replace it.

Parts
Cause 6Incoming Power Problem

The electrical outlet might not be getting power. To determine if the outlet is getting power, plug an electrically-powered unit into the outlet and see if the unit turns on. If the outlet does not seem to be getting power, check the circuit breakers or fuses to identify the problem.
