Excessive humidity in a space can cause all sorts of problems, including water damage, mold and fungal growth and even minor flooding. Whirlpool dehumidifiers are very useful in reducing the humidity levels. With proper care and maintenance, your Whirlpool dehumidifier will continue to provide good service for years. Performance problems can occur, however. A few simple troubleshooting steps can help to resolve problems and get your humidifier working properly.

Check that the unit is plugged in.

Ensure the Humidistat Control is not set to the Off position. Also, try a drier setting.

Ensure the correct capacity fuse is used for the circuit.
