How to fix a dehumidifier that is not working?
Here are a few easy to fix dehumidifier issues: Complicated dehumidifier issues normally involve tweaking internal parts or disassembling the unit to repair or replace. These issues, on the other hand, need special tools and knowledge especially to certain parts like the electricals and motors.
What is a compressor dehumidifier capacitor?
The compressor dehumidifier contains two essential capacitors, i.e., a compressor capacitor that helps run the motor and a fan motor capacitor that helps run the fan. The compressor capacitor stores the charge needed to start the compressor. This helps to protect the capacitor motor while ensuring a consistent supply of current to the compressor.
How much does it cost to replace a dehumidifier fan motor?
If there are no power conduction issues, but the fan still won’t run, contact an electrician or a dehumidifier expert to replace the motor. The price for blower fans ranges between $10 and $30, depending on the quality and your unit type.
Why is my compressor dehumidifier leaking refrigerant?
Compressor-based dehumidifiers rely on refrigerants to convert moisture to water. The refrigerant is housed inside the coils, mostly made of copper. However, due to corrosion, factory defects, or normal wear and tear, the refrigerant in your unit could start leaking.
Why is my dehumidifier compressor not working?
The culprit could be a dirty fan or a broken fan blade. If comfortable checking inside the unit, unplug it and then remove the cover, then turn the fan blade by hand to see if either debris or a broken blade is keeping the fan from turning.

Why do dehumidifiers quit working?
If your dehumidifier is not making water and you have verified that the ambient temperature is above 65 degrees Fahrenheit, then you may have a faulty fan motor. For proper operation, a dehumidifier needs to have an adequate amount of air blowing across the evaporator coils to prevent frost or ice buildup.
Why is my dehumidifier running but not collecting water?
If your dehumidifier is not collecting water even though the room temperature is over 65 degrees Fahrenheit, there may be an issue with the capacitor in the compressor circuit. The compressor circulates refrigerant through the unit to remove moisture from the air, which collects in the bucket.
