Danby dehumidifier not working

Danby dehumidifier not working. Danby Dehumidifier is a brand of dehumidifiers that condenses moisture from the air.

When dehumidifiers are turned on, they take in cold air via the intake vent and pass it over coils full of refrigerant gas.

The gas lowers the temperature in the coils to below freezing, which causes moisture in the air to condense on them and drip into a bucket where it can be easily drained away.

We recommend performing the bucket switch test to see if the problem is related to the switch.

If it comes back faulty, replace it and continue on your diagnostic journey.

We also recommend checking the humidistat and doing a continuity test on it, which will indicate whether we have a defective humidistat that needs to be replaced or not.

Remember to always follow all manufacturer’s instructions and consult the relevant user guides for specific details pertaining to how you should approach the described diagnostic tests yourself.

Defective Control Board

Dehumidifiers use a control board to monitor air moisture. Contacts close when the amount of moisture detected by the control board is too high, enabling the compressor to run.

Your dehumidifier may not work if the control board is malfunctioning.

Humidistat problem

The humidistat measures the amount of moisture in the air. To prevent the dehumidifier from running when the air is too humid, the device closes its contacts.

There will be no continuity if the humidistat’s contacts are broken, and therefore the dehumidifier will not run.

Test for continuity using a multimeter to determine if it’s defective.

This component of the system will no longer be required if not present, and therefore can be removed from the system.

Sensors that measure humidity

The humidity sensor allows the dehumidifier to run when moisture levels are too high.

If the humidity sensor is faulty, it won’t work correctly and so the dehumidifier won’t start up as needed.

 Faulty Compressor

It is a pump that compresses the refrigerant and circulates it through the evaporator and condenser coils.

A faulty compressor will prevent the dehumidifier from cooling properly.

In most cases, however, this is not the case – before replacing it, first check other common-failure components.

Testing the continuity of your compressor using a multimeter should be at the top of your list if they are fully functional with no issues.

Incoming Power issue

To determine whether or not your electrical outlet is receiving power, plug an electrically-powered unit into the outlet and observe if it turns on.

If the outlet does not seem to be receiving power, check your circuit breakers/fuses to identify the culprit.

The bucket switch has no continuity

If the bucket switch malfunctions while it is open, the dehumidifier will not function properly, which will result in excessive moisture in your home.

In order to determine if the bucket switch is defective, you must use a multimeter to test it for continuity. If the bucket switch does not have continuity, replace it.


If the humidifier is turned on but the reservoir is not filling up when the temperature of the air is higher than 65 degrees Fahrenheit, it’s possible that the compressor may have malfunctioned.

Since there are a number of factors that could cause this, it would be best to consider replacing the motor as soon as possible.

Suddenly, the fan stopped working

The fan in a dehumidifier is always blowing air out—never in.

The fan exhausts stale, warm air out of the house to be replaced with fresh, humidified air that has been pulled in through the appliance’s intake port which also happens to feature a washable filter.

If the filter gets dirty or clogged and prevents fresh air from entering inside then obviously this means the dehumidifying process can no longer work effectively.

Sometimes it could just be that the bulb inside the fan needs replacing. Other things that could cause problems are a broken fan blade or defective wire connections.

 Blocking airflow

if the fan is in good working order, then it could be that something has blocked the airflow into the unit.

This can easily happen if a dehumidifier or humidifier is left next to furniture or fabrics as these items could stick onto the grills, restricting airflow.

It’s important to have your machines a foot away from anything soft like curtains, carpets, furniture, or rugs as a safety precaution.
