77319 LG Refrigerator - Instructions

Unplugged the refrigerator, Taped around the edges of switch as I had read to prevent possible scratches, used very thin flathead screwdriver to pry out old switch, unplugged old switch, plugged in new switch, put it back in opening, plugged fridge back in, and I had beautiful light! Hardest part was unplugging the refrigerator!

This is bottom drawer type frige. Icemaker is inside (not in the door) and hard to reach. I first tested the solenoids by disconnecting them and using a test cord, energized them independent of the frige wiring. They worked ok. Note: this frige has (2) solenoids going to the icemaker. And it has (3) solenoids serving the water dispenser. The icemaker solenoids are wired in parallel. I removed the icemaker by removing (1) screw from the bottom and loosening (2) on the top. Then removed icemaker as a complete unit disconnecting the wire connector at the same time. On the bench I tested the icemaker to verify it was defective. The wire harness has a 10 amp fuse in the black wire (hot wire). `The fuse was blown. This was sufficient to indicate the icemaker is shot. I did however, do some other tests. Cold resistance of the mold heater was 72 ohms. The timer motor was 4000 ohms. These measurements should be ok. I then activated the icemaker with a test cord, bypassing the blown fuse. The unit cycled one complete rotation then stopped. The mold heater worked. I tested the amp draw on the mold heater and it was only .1 amps. I should be a about .8 amps. I then cycled it again and then the timer motor began to sizzle and smell. Then it smoked and stopped mid-rotation. I then purchased a new icemaker. I believe the mold heater was going bad over time as this unit made ice but very slowly. This put extra strain on the motor as the mold was not releasing quickly. This damaged the motor causing it to fail.

Pulled fridge away from wall, unplug electrical connection, open fridge door, use knife to prize out door switch, pull off and replace switch from electrical wiring.

pried out old switch, disconnected wires ,placed wires on new switch

1st, emptied top freezer basket, used drill to remove 3 mounting screws, held new rail guide in place, installed same screws into freezer wall. Hand tightened with hand screwdriver to avoid over torquing with drill.

Used a screwdriver to take off broken clip and then used same screwdriver to replace with new clip. Very easy.

I had previously watched a YouTube video (do this first!!) on a similar Kenmore model so I knew what to look out for: (1) turned off power, (2) took thin putty knife to slip under outer lip of switch (most screwdrivers are too thick), (3) wiggled switch at front end to release the tab, (4) unplugged from the socket, (5) plugged in new switch, (6) popped new switch back into door, (7) turned on power. Voila !! Super easy. I couldn't believe it.

Very simple
Removed wire rack
Removed 3 phillips head screws, requires large phillips screw driver
Removed old rail guide
Installed new rail guide and screwed back in place
Reinstalled rack

Used a screwdriver to remove covers. Used a blow dryer to defrost coil in freezer. Cut zip tie and removed old controller assembly. Inserted new controller assembly and secured with zip tie. It took 24 hours for the fridge to cool completely. Now it works fine.

After noting frost in freezer Right rail started to jam. Noted freezer door was closing crooked. Rail replacement resolved issue. It had been frosting up for some time so Rail must have been broken for a while. Check door seals they were not closing flush.

Removed old rail by unscrewing 3 screws and put new rail on

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.

removed 2 screws and replaced them on new part. Very easy.

Pull off the grill cover and remove the 2 screws from the old part and simply screw in the new part. Don’t lose the screws there are no new ones with the new part. Replace cover.
