LFC21770ST (AST4LGA) LG Refrigerator - Instructions

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.

The 2 minute or so video was not exactly matching the model that we had but the instructions were very good and important. The switch was a little difficult to get out from the side of the refrigerator.

Now that you have to buy a complete assembly that includes the drawer in the classy window it's very simple to replace however you buying parts that you don't need simply because G no longer makes the window. Which I find rather odd being as though that they make the whole assembly think and sell windows by themselves for less than 2/3 of what I spent through the whole assembly

I just popped in the new cover lamp. It took less than 5 mins. if that much.

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.

My son just pried out the old switch with a screw driver snapped out the old one and snapped in the new one. Pretty sure even I could have done this. Very quick and easy. Thanks. :-)

Go to this site on You Tube to watch the "how to" replace the gasket retainer. The retainer I needed did not come with brackets or the cam you will need. You will need transfer them from the old retainer to the new one. Not hard, just be mindful of position of the items you remove to put them back in place the same way. A metal rod holds the brackets and spring in place with a screw on one end to prevent rod from sliding off retainer. The cam has a screw that holds it in place, use from old retainer. If the old cam is not broken use the one from the old retainer. It is not hard and you will save $$$ that you would pay an appliance repair company.

Remove door seal and cam shaft (one piece). Remove broken cam by removing Philips head screw. Replace broken cam with new cam and reassemble. The actual repair took about 15 minutes however the majority of time was spent figuring out that the door seal and cam shaft had to be removed, no tools required.

Unplugged the fridge. Used a screwdriver to loosen the switch. Easy to disconnect from fridge and just plugged the new switch in. Popped right back into the side of the fridge and worked perfectly.

slid screw driver under edge of switch, easy.

I popped the old switch out of place and then disconnected the wire harness from the switch with a pair of needle nose pliers. I then inserted the harness into the new switch and popped the switch into place. Super easy and fast.

unfortunately my fridge stopped working. I purchased another but wanted to try and repair the old one. when ew one arrived, the old one was supposed to be put in garage but instead was hauled away. Had delivery return next day but they had as already removed and lost the handle screw for the bottom freezer and the screw that holds handle in place. ordered the handle screw and picked up the nut. very simple to install the screw and put handle back on.

Removed white plastic trim and installed new latch / cam shaft

Simple replacement part.
