KUIA18PNLS5 KitchenAid Ice Maker - Instructions

I determined the pump was not working by running the ice maker. After it started a cycle, I could fell the underside of the cold plate to insure it was indeed cold, but no water was flowing.
First, be sure the water pump electrical plug is in., it releases by pressing together the tabs at the ends, not sides.
To replace the pump, turn off the water supply and cover the drain hole at the bottom of the ice bin so you don’t drop parts down it. The screw-plug at the bottom of the water tank or a quarter will do.
Remove the water tank below the pump by taking out the thumbscrews at both ends. You can then see the hose at the bottom of the pump. If it is off, that may be the problem.
To remove the pump, pull the fill hose to the left out of the slot and bend it behind the pump to get it out of the way. Unplug the electrical connector and the pump hose. There are three ¼” hex head screws, teo on the side wall, one in back. The middle one is the hardest to access. I used both a nut driver and a socket wrench with a 4” extension.
When installing the new pump, be sure to plug in the electrical connector, the discharge hose at the bottom and position the fill tube as you found it. Forget any of these and nothing works. Re-install the water tank, replace the drain plug and turn on the water supply, in that order.

We guessed what the problem was and we were extremely fortunate that we guessed correctly. The part was not technically difficult to install just a little awkward to get to. My husband had no trouble although he did take the machine out of it's space and lay it flat on the floor. One benefit of this process was being able to clean some of the areas that are almost impossible to get to when the motor is in place. It was well worth the extra shipping charge to get it before the weekend.

Follow the instructions already submitted by others. As mentioned be sure to place towel inside to cover the drain. My 3-wire electrical connector also had some corrosion build-up so I had to remove the bracket holding the connecter cut the 3-wires and install a new connector. Not a big deal, you are just working in a small enclosed area. Pulling the entire unit out and either elevating or tilting back helps with the access. Be sure to check drain connection in the back of the unit when putting back in place. Having a headband light helps for entire repair.

I replaced the thermometer first and it started working again. I was convinced that the reason that it continued to break every 6mos was because no one had ever replaced the fan. The difficult part was getting to it. After trying to get in from the front and from the back I finally figured out that I had to take the bottom off and tilt it on its side. I was then able to get out the pin in the condenser and move it to the side. I could then reach the screws that held in the fan. I then decided to put the fan on the motor and when I was tapping it on with a hammer the back cracked. I attempted to fix it by taking apart the old motor and salvaging the parts but that didn't work. I had to buy another $85 part and take the whole thing apart again. It was easier the second time because I knew which screws and pins I had to remove and how to get to them. I very, very carefully tapped the fan onto the motor and now it is working fine. I will let you know if it is still working at Easter. If it is I will have done a better job than the 7or 8 repairmen who have fixed it in the past

didn't go well at first. Got it all hooked up relatively easily but it didn't work. Called customer service who suggested hooking pump up to other power source to be sure it worked. It still didn't work. After closer inspection a connection wasn't hooked up on pump. After connecting got it back in about 30 min. Working like a charm now.

The repair went just fine. Your instruction regarding using the wiring harness were clear. Most of all I am happy to not have to listen to a noisy motor all night.

I tried WD40, it worked for a day. Got a new part from PartSelect.com and was a good brand. Panasonic. Easy fix and works great. Saved a bundle. I priced a new fridge, no way, this was better. Thank you Partselect.

fan motor housing had to be drilled through both sides of housing to attach to existing bracket. Possible damage to wiring inside the unit may disable condensor fan motor when motherboard is replaced. (Motherboard on order.)

Removed to old motor by removing screws and disconnecting power source and replaced with the new motor and plugged back in power source

Using a 1/4" ratchet removed the old motor, a bit difficult due to small space to get your hand and ratchet in position. Before installing the new motor I used one of the screws to tap the the 3 holes in the new motor so it would be easier to start the screws attaching motor to mounting bracket. Attached cable. plugged in the fridge. Great to hear a quit running refrigerator again.

as told per compter

I pulled the back panel covering the fan and condenser off the refrigerator (just a few screws) and disconnected the fan which was a simple plug. The fan was held in place with three screws which I took out. I pulled out the old fan and replaced it with the new one, three screws to secure it in place and reconnect the fan plug. Then simply replace the back panel and plug the frig in. the fan silently started right up. Good as new and no service call! :)

My husband watched the video on the repair and followed it step by step...works like a charm! The repair shop wanted 299.55 to fix it - the part was 79.00....big savings by doing it ourselves.

Unplugged the refridgerator and pulled the rear cover. Had to take the fan blade off in order to get at the screws holding the existing motor in place. Removed the old fan. Pressing the new plastic fan onto the new motor shaft was a little more effort than expected, but I guess it won't come off. I have large hands so mounting the new unit was a little bit of a challenge getting the small screws started. Once the three screws were tightened all I had to do is plug the electrical connector in and replace the rear cover. I was happy that the existing electrical connector was the right one for the new motor too, and that I didn't have to use the provided wire harness. All in all the repair went pretty well.

Watched the video that was attached to my order confirmation (great idea) and just followed it step by step. Real easy repair since I had tried to fix the noise first without ordering parts, so I knew what I was doing Did a temporary fix which quieted it down while I waited for the parts and then the repair itself was pretty straight forward.
