78552 LG Refrigerator - Instructions

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.

The heavy work is moving the fridge, then take off the lower plans. Use a bowel or cup for screws and the water line connector spacers so you don't loos them.
undo connections holding water line, including the bottom brakes for the solenoid. Reuse the spring around the lower waterline to prevent external wear on the line.

NOTE: remove the waterline connector spacers and save!
NOTE: you must compress (not pull) the connect to then pull the waterline out of the connectors.
NOTE: You must also remove the water filter and housing inside the fridge but this is easy.
MOTE: Test the line for leaks by turning on the water and then using the door water. The filter will need to refill so it may take a minute before water comes up. This line only have pressure when the door water is used or the ice maker needs to make ice.


After replacing the line, test the line for leaks by using the door water so the solenoid fills the lines

Switched the refrigerator circuit breaker to off. Put tape around the switch to prevent scratches. Wedged the putty knife into the right side of the switch and pried up.the switch and connector popped out. Removed the connector from the old switch and connected it to the socket in the new switch. Stuffed the new switch and connector back into its home. Switched on the circuit breaker. Now we have light in the refrigerator with every opening!

Part Select had a great video which made the repair easy, using a putty knife to start removing the freeze door gasket. Once removed the install is simple just snap the new gasket into the track, but start at the corner. Other company's have a video requiring you to remove the entire freezer compartment out of the appliance, unnecessary waste of time and labor.

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!

viewed video and followed instructions was a piece of cake

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.

Followed instructions online

Replaced old hose and installed the new one. Was very simple with the instructions in your email..... step by step, could not of been any similar.... you guys rock

Removed old rails and tapped new rails in place. The big problem was finding how to fix the drawer. After searching many online websites, It was my good fortune to find Partselect and a one of their service representatives who
knew how to fix my drawer
and they had the part.

Simply removed old gasket. Started in a corner with installing the new gasket. It went in easily and quickly.

Simple replace of door, fits perfectly

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

Watched a couple of YouTube videos and then went at it

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.
