Comfort-Aire parts

Comfort-Aire is known for their durable consumer appliances, including their dehumidifiers and room air conditioners. With proper care, these appliances can last for years. If your Comfort-Aire appliance appears to be breaking down, it may just need a replacement part.

Common issues with dehumidifiers

If you've noticed that your dehumidifier is running constantly, there could be a few different reasons why. Consult your owner's manual and make sure that the size of the dumidifier is appropriate for its coverage area. If it's trying to handle too large a space, it may simply be unable to keep up. However, if this isn't an issue, then the reason is likely a faulty internal part that's keeping the dehumidifier from working.

Your dehumidifier relies on a humidity sensor to monitor the humidity level. If the sensor is dirty or faulty, it may not work properly and cause the unit to inadvertently run all the time even if the air is actually at the proper humidity level. There might also be an issue with the compressor. If the compressor is leaking or broken, it won't be able to remove water from the air, and you'll need to have a technician replace the compressor to get your dehumidifier running properly.

Dehumidifier parts that often need to be repaired or replaced

  • Humidity sensor—Also known as the humidistat, the humidity sensor monitors the humidity in the air that passes through the evaporator and activates the compressor when necessary.
  • Evaporator thermistor—The evaporator thermistor monitors the temperature of the evaporator coils. When the temperature drops too low, it defrosts the evaporator coils so that they don't ice up.
  • Fan motor—This pulls air through the front of the dehumidifier, passes it through the evaporator coils and pushes the air out through the back past the condenser coils.
  • Compressor—The compressor circulates a compressed refrigerant gas through a sealed internal system from the condenser coils to the evaporator coils.
  • Condenser coils—These are a heat exchange system on the back of the dehumidifier. When the refrigerant passes through these coils, it's cooled and condensed and then it passes through the evaporator coils.
