How to replace a dehumidifier user interface control board

This DIY repair guide explains how to replace the user interface control board on a dehumidifier. The user interface control board lets you program the dehumidifier. If the user interface won't respond when you push the buttons, replace it with the manufacturer-approved dehumidifier part.

This basic procedure works for Kenmore, LG and DeLonghi dehumidifiers.
