LFC21776ST LG Refrigerator - Instructions

Installed new one.

Read the reviews from other members and just did as they said. Needed a screw driver and the info from past persons review couldn’t have been easier.

I took a very thin bladed screwdriver and took the old part out -carefully.
The new part fit in quite easily.

Replace with new switch. this is the third switch i have replaced in 10 years. the only part, besides a light bulb, that has gone bad. obviously this is a problem with this model for Kenmore, or just poor switch design.

Simple replace of door, fits perfectly

Unplugged the frig and removed two phillip screws on flapper door of left door... Unplugged the electrical connector and removed flapper...
Picked up new flapper and snapped electrical contractor together... Slid new flapper bar into place and inserted two phillip screws... Job complete in 15 minutes...

I am a73 year old woman. If I can do this, anyone can. Super easy. Just watch the online video.

Removed mullion strip with Phillips screwdriver replaced spring reinstalled the mullion strip all in about 15 minutes.

I have moderate to good mechanical skills, but getting the old switch out was a sizeable challenge. Since this switch suffered some damage during extraction, I was lucky to have ordered a new one to replace it. Reinstall took approximately 90 seconds. PartSelect saved me an expensive service call.

Take out 2 screws and unplug unit before removing. Plug-in new unit and screw in 2 screws. That's it.

Just had to slip the 2 pegs into the existing holes.

Followed Youtube video provided on the PartsSelect Website:

Made installation of the new part a piece of cake. Easy peasy!! Took less than 10 minutes.

The spring broke on the flapper (mullion) on my refrigerator. I sent a chat message to PartsSelect (they answered right away) to see if they had a replacement spring but it was not available so had to order the whole mullion. They gave me the part # I would have to order. It arrived quickly. The new mullion didn’t have a visible spring but it worked the same if not better. I just had to remove 2 screws on the center plate on the existing mullion, pull the plate out enough so you will be able to slide the mullion (the wires are under the plate kind of like the ones you see on a ceiling smoke detector) but you can’t get under the plate until you release the mullion. Push up on the mullion so that the plastic tabs on the top and bottom are released. Once the mullion is released (you have to hold it), you’ll see the wires. Unhook the wire part by just pushing down on the little tab and remove it. To install the new one, just reverse the steps. Align the top and bottom plastic tabs to fit into the slots, just enough to hold it in place. If the plastic tabs are not already flipped out, you’ll have to just flip them out. The top tab does not have tension but the bottom tab has tension so just push on it with your finger to flip it out. The plate covering the electrical is a rather tight fit and you have to make sure the little tab on the inside of the plate is above and behind the tab on the inside where the wires are so it slides behind it so you can get it in position before sliding the mullion back down into place and the electrical plate is in place too. Then screw the 2 screws back in. The hardest part is holding the mullion while un-attaching the electrical and just make sure you stuff the wires in enough so you can get the plate back in position. I’m a 75 yr old woman and managed fine by myself. At first when installing the new one, I couldn’t slide the mullion down enough to get the electrical plate in position and then realized I had to have the little tab inside the electrical plate behind the tab inside the wire compartment so they didn’t hit one another when pushing the mullion back down. Then, all went fine.

The refrigerator had the above code and when I check on YouTube, it explained that the defrosting was not working properly. It was taking more than 80 minutes to defrost. I ordered the Temperature Sensor first and it was not the issue. I also ordered the Defrost Temperature fuse or the Thermistor. I had to defrost the refrigerator first by using a portable heater to get it done quickly. (See Youtube on how to get to the Defrosting Unit inside the freezer). The Thermistor was the wrong part. I called the Partselect and explained that the part with the heating element is one piece. (Heating Coil Thermistor or Heating Coil). By replacing that piece solved the Error Code issue. I listened to Youtube for the instructions on how to replace the Heater Coil. So if you see the Error Code dH F, you need to replace the Heating Coil, which comes in
one piece and sits on the bottom of the Defrost Element.

Cover the putty knife with tape so you do not scratch the side wall where the switch is located. Slide the knife under the edge of the switch and push in a bit towards the switch and slightly twist to pop the switch out of its hole. Disconnect the wires from the switch and simply plug in the new switch. Push wiring back into the hole and careful push the switch into the hole until it snaps into place.
