How to Troubleshoot a Fedders Dehumidifier

Save

Fedders dehumidifiers remove moisture from the air as it passes over a set of evaporative coils. Over time, the moving parts inside the unit can break down. Another common cause of dehumidifier problems is frost on the coils. Fortunately, you can usually troubleshoot and correct the issue on your own without paying expensive repair fees. Be sure to use only Fedders-compatible parts if you find any defective items that must be replaced.

Things You'll Need

  • Owner's manual
  • Circuit tester
  • Replacement parts (if necessary)
  • Make sure the dehumidifier is plugged in and that your home's circuit breaker switch does not need to be reset. Replace any blown fuses you find at the breaker box.

  • Consult your owner's manual to find the dehumidifier's temperature rating. If it is not listed, the general rule is that a standard thermostat is rated down to 65 degrees. If you live in an area that frequently gets colder than this, you may have to buy a dehumidifier that is rated for lower temperatures.

  • Empty the water tank if your dehumidifier will not turn on at all. If it is already empty, the water level sensor may be faulty. If this is the case, replace the float inside the tank and the switch that it triggers.

  • Clean the air filter if your dehumidifier seems to run for a long time without filling up the water tank. If this does not correct the problem, there could be a fault in the refrigeration system that must be serviced by a qualified technician.

  • Use a circuit tester to check the fan motor if no air is blowing. Replace the motor if it is defective. Make sure the fan is not stuck and that there are no broken or cracked blades.

  • Look for frost or ice on the evaporative coils on the rear of the unit. This will prevent the moisture in the air from condensing onto the coils as the dehumidifier runs. If this is the case, shut off the dehumidifier until the coils defrost or move it into a warmer area.

Tips & Warnings

  • Consult your dehumidifier's owner's manual or the Fedders website for additional troubleshooting tips.
  • Make sure the dehumidifier is unplugged or the circuit breaker is off before you attempt to remove any parts.
