My unit works perfectly for 4-5 days then just cuts off
For model number KUIC18NNXS1

Hi Robert, thank you for your question. You may want to check your water inlet valve to see if it is working or not. Testing it with a multi meter, it should read between 5 - 1500 ohms. to be working. If that part is fine then you should go on to check your pump. and your thermistor as well. It all of those parts are fine then you may want to take a look at your control board being the issue. Good luck with your repair.

Ice is melting slowly on hot wire grid and not dropping into bin.
For model number KUIC18NNXS1
PartSelect logo
Hi Ryann, thank you for contacting us. The issue could be with the ice cutter grid, part number PS11740334. It uses heated wires to slice the ice produced by the ice maker into smaller, more easily dispensed cubes. You may need to replace it to fix the issue. We hope this solves your problem!

Everything is operating properly, but the freeze plate won’t get cold. It worked fine, I cleaned it and shut it off when we left for the summer. When we returned it will run, but not make ice.
For model number KUIC18NNXS1

Hello John, thank you for getting in touch. Dust, debris, or objects blocking the air inlet or outlet vents can restrict airflow and prevent proper cooling. Clean the vents and ensure there's sufficient space around the ice machine for air circulation. Ensure the freezer is set to the manufacturer's recommended temperature (usually around 0°F or -18°C). A leak in the sealed refrigeration system can lead to low refrigerant levels and reduced cooling capacity. A leak can be identified by unusual noises like hissing or bubbling, reduced cooling performance, ice buildup on the evaporator coils, and increased energy consumption. The compressor, part number PS11756696, is responsible for circulating refrigerant. If it's not working correctly, the freeze plate won't get cold. We hope this helps.

Seven year old condenser fan was making noise when it was running.
The process to repair was very simple, I removed the back of the refrigerator to expose the motor area. I then removed three screws that held the condenser motor in place. once it was loose I detactched the electrical harness and removed the old motor. I then placed the new motor in place and secured it with the screws and reattached the new electrical harness that came with the new part. Once completed I reviewed it to make sure I didn't miss anything. I then replaced the cover over the motor area and enjoyed my success in repairing my own appliance with no added cost for labor, which would have been expensive I'm sure. The part purchased came with clear and consice instructions very easy to follow.

Broken light switch
Took all the screws out of the plastic shroud that encloses the switch .There only four that I needed to remove, were the two in front where the switches that go,they go in horizontally and two in the back with large washers on them that hold the back to the top of the box that go in vertically.The switch was a snap ( make that two snaps ) the wiring is almost self explanatory. then it gos back to the way you took it off. OH! and don't forget to turn the light bulb all the way back in to the socket , so the light will work after you take the time to install it yourself.I had the water supply line from under the box to the water dispenser in the door and the total bill on that was one hundred thirty seven and a hand full of change.Don't be afraid to do it yourself the savings is enough on one one item to make several months payments on a new one Randy the "Handy Man'

Fridge made noise and the center post was HOT!
We have a side-by-side fridge/freezer and we experienced a hot center post (where doors come together) and the fridge made loud noise. Also, the (old) fan motor would start, but then quit, so our issue was the motor.

For me the repair was very easy, but for an unexperienced person it may prove to be difficult. If you must order a motor/fan, do NOT order the metal fan as a plastic fan comes with the motor. What's strange is the new motor is different than the old one, but it still mounted without any required modifications. I did NOT use the wire harness that came with the motor either as it was different too, but my old one was still good.

Check all of your parts as my fan had a cracked blade, but I used "superglue" and it's fine now.

Fridge stays cold and my wife had to lower the temperature in the fridge as she was blasted by the cold!
