Most common Westinghouse deumidifier parts that need replacing

1. 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.
2. 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.
3. 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.
4. Thermistor. The thermistor is a temperature sensor that’s connected to the dehumidifier’s electronic control board through a wire harness.

How to fix your White-Westinghouse dehumidifier when it doesn't remove moisture

After you first plug in the dehumidifier, give it 3 to 4 days to reach and maintain the humidity level you set.

To allow adequate air flow, place the dehumidifier at least 6 inches from walls.

So the dehumidifier can work efficiently, clean the air filter and grille if it's dirty.

If the dehumidifier's capacity is too small for the space, it can't remove humidity adequately; consider adding another dehumidifier to the area.
