LRFC21755ST LG Refrigerator - Instructions

Video makes it look easy. Kenmore refrigerator does not have "groove" along the right hand side of switch that allows for pushing down on release. Used a thin screwdriver to get under to push while holding switch edge with pliers. Kept slipping. Tape sides to avoid scratching inside of refrigerator.

Turn off power, remove upper and lower drawers (may need to open upper refrigerator doors to remove large freezer bin,) remove drawer supports (upper and lower), remove rear freezer panel (trick is to loosen 4 screws on fan bumpout to get the panel to come free from the freezer side wall), test thermistor with multimeter (should have continuity or near zero resistance across 2 orange fuse wires) before cutting zip ties, cut zip ties holding Thermistor in place, remove old Thermistor, install new Thermistor, install new zip ties, replace rear freezer panel, install upper and lower drawer supports, install drawers, turn on power, should be fixed if error code doesn't return after 6 hours.

The replacement was the exact size,easy installation.

As per utube

The replacement part came in a timely manner and snapped right into place.

Compress the ends. It snaps in

I followed the directions! It was so easy that I bought another switch for my sister's fridge (same as mine). Her light was out too!

Remove the crisper drawer for room to work, locate the two mounting holes at the top, front of the shelf, insert the plastic hinge pin on the outside wall side. Holding the front(cover0 in one hand, reach under the cover with your other hand, grasp the second hinge pin and move it to the insert position. Using your index finger, carefully bend the bracket arm to allow the pin to be inserted.

Have had the Sears repairman come to the house to replace this part in 5 minutes for +$100.. twice. When my dad's stopped working, ordered the part and replaced it myself for the cost of the part and shipping.
Use a screw driver to pry the right side of the switch and pull out. Best to watch a youtube video first. Takes about 5 minutes.

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!

Insert one side and squeeze other side to slip in.

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 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.

After watching a few iTunes videos I was able to order the light switch from part select and within a week I had the new switch. I had a little trouble getting the switch out. I used a flat screw driver and taped around the edge to keep from damaging the wall inside. I found the clip on the right side and had to use some force to get it popped out, you may need to use pliers to disconnect the switch.

The old switch was a little hard to get out....took me a couple tries. I couldn’t move the frig out to unplug it, so just shut the power off in the kitchen. But, I was happy that’s what the problem was and so happy to have the light back on......it was probably three years it didn’t work!
