How to Troubleshoot an LG Dehumidifier LHD30

The LG LHD30 dehumidifier is meant for residential use and is designed to remove excess moisture from the air and return cooler, drier air back to the environment in the home.

The unit offers a humidity control dial, automatic shut-off, variable fan speed and removable water reservoir. Available for purchase online or in select heating and cooling supply stores, this dehumidifier ought to function well with regular maintenance and care. If problems do arise with the unit, troubleshooting methods may assist you in determining the cause and finding a solution.

Plug the LG dehumidifier firmly into a power outlet if it is not working. Check the fuse or household circuit breaker and replace or reset as needed.

Adjust the dehumidifier control to "Max" if the unit automatically shuts off but you desire additional moisture removal. Wait for the unit to begin operating and then turn the control dial to the desired setting.

Turn off the dehumidifier and empty the water reservoir if the "Auto Shut-Off" light is illuminated. Carefully remove the water reservoir and empty it into a sink or tub. Restore the reservoir to the unit.

Adjust the control dial to a lower humidity setting if the unit is running excessively. Close windows and doors to help maintain lower humidity in your home. Use a brush to clean dirt or debris from the front grille and from the coils on the back of the unit. Dirt and debris may prevent proper air flow. Keep the area around the dehumidifier clear of objects that may obstruct air flow.

Turn off the unit or lower the humidity setting if frost appears on the coils. This typically occurs if the room temperature is below 65 degrees Fahrenheit. Set a towel under the coils to catch the melting water.
