ACTIVE CARBON FILTER 00636458

I emptied and powered the refrigerator off. I placed two large cooking pots full of hot water in the refrigerator section overnight with the doors closed. By morning, most of the ice was melted, enough to be able to pull off the Styrofoam that covers the coil.
Starting with the stainless steel cover containing the control module, I removed the four star bit screws. It is a bit tricky unclipping the top portion of the cover from the clips, but with some patience and proper delicate force they yielded.
Once inside, slide the plastic covers from where the sensors and control panel plug-in off and unplug the control panel, sensors, and heaters. As stated earlier, you can now remove the two plastic retainers and steel bar that hold the Styrofoam insulator in place. Next, you will need to remove the drip pan and defrost heater assembly. On either side, you will see retainer clips at the end of what appears to be the track that the drain and heater assembly sit in. Using a small screwdriver, push in on the plastic retainers holding the assembly in place while gently pulling out on it. Once removed, This will provide access to the evaporator fan, which can now be easily removed. Lastly, there are two clips that hold the evaporator coil in place. Gently pull down on the evaporator coil to unclip to expose the defrost sensor. Once the defrost sensor is unplugged, the Styrofoam that it is attached to slides out from above the coil so that you can replace and tape the new sensor in place.

Reinstall everything in reverse order, making certain that everything is plugged back into its proper receptacle. Power the unit back on and enjoy.!
