Troubleshooting your KitchenAid dehumidifier when it won't turn on

• Test that the electrical outlet works by plugging a lamp or small appliance into it. If there's no electricity to the outlet, reset the house circuit breaker.
• If the electrical outlet works, check the power cord for damage. Repair any damaged or broken wires in the power cord or replace the power cord.
• If the power cord is good, check the wiring connections on the electronic control board and user interface control board (with the dehumidifier unplugged). If wiring connections are okay, then you may need to replace the user interface board and/or the electronic control board.

Common KitchenAid dehumidifier replacement parts

• Air filter. The air filter is behind the grill in the dehumidifier case. The air filter traps dust and debris in the air that would contaminate the evaporator fins and condenser coils.
• Electronic control board. The dehumidifier electronic control board controls the major electro-mechanical components in the dehumidifier. The electronic control board monitors input from the humidistat and activates the compressor to dehumidify the space when humidity exceeds the level the user sets. Input from the thermistor (temperature sensor) on the evaporator is also used to detect frost on the evaporator. The electronic control board shuts off the compressor when excessive frost builds up on the evaporator. With the compressor shut off, the frost melts and the condensate water drips into the collection bucket. Once the fins are clear of frost, the electronic control board restarts the compressor if the space needs dehumidification.
• Humidistat. The dehumidifier humidistat is a sensor that detects the water vapor or percent of humidity in the room. The humidistat provides input to the dehumidifier’s electronic control board through a wire harness connection.
• Thermistor. The thermistor is a temperature sensor that’s connected to the dehumidifier’s electronic control board through a wire harness.
