Unscrew and detached front and back panels, and inside framework holding the sheet metal to the body, after removing the sheet metal, unscrew the box enclosing the control board, use needle nose pliers to unhook the sensor module from the board and place the new sensor into the spots where the old sensor was connected (thermostat area, humidity Sensor, bucket switch, and control board). Close up the unit and your good to go.

Had to pop open the back. The back did not just unscrew and come off. It has to be pried off carefully. Took the turbo off and put the new one on.

released broken wheels from their position using a screwdriver and secured new ones w/ a pliers.

We had no problem installing the product.

removed the front cover housing the switch circut board. Removed the defective unit and plugged in the new part. Unit now works fine.

taking apart and testing switch and connections, then searching online and finding the exact problem and part needed

I really like this dehumidifier it has a feature I cant find on any new ones. 2 hours on two hours off. This works very well for me. Humidistats on all I have tried do not work well, they turn on and off every couple minutes very aggravating. So for the 3rd time I needed to replace fan motor old motor bearing ceased up. I researched online for new dehumidifier and came across LG fan and motor at Parts Select for less than $20 bucks it is up and running. Took almost a month for the motor to arrive but it is worth it. also motor needed a capacitor that my old motor didn't need. Luckily I had a spare capacitor from a pool filter motor I repaired years ago. Thanks Parts Select your going to be my first choice on my next appliance repair.

remove outer shell and control panel. take cover off off electrical connection box. remove old sensor from front of condensing coil along with wiring harness to temperature sensor and bucket switch and circuit board. reinstall new sensor in the reverse procedure. reinstall covers.

Took the cover off and removed old sensor the new one plied wright in no problems anyone can do it

Replaced the sensor and solved the problem. I had a lot of difficulty with the case holding the circuit board,etc because no easy way to service. Seemes they could have made it easier with a removable panel. I actually cut the wires and re-attached the thermister later after routing. Did not use the other parts of the wiring.
