Geno - For model number LSC27921ST

Changed water valve! No water to ice maker! Worked slow before!
Chris Boyle Profile
Hi Geno, thank you for reaching out. As you have already replaced the water inlet valve, we would recommend checking the water tube, part number PS3526623. It supplies water to refrigerator components that require water, such as the ice maker and water dispenser. You may need to replace it to fix the issue. We hope this solves your problem!

The ice tray had warped and dumped water, which then froze down through the ice bucket and below.

To replace the warped tray, I found the service manual (pg. 124 below) which took some interpreting.
Removed the lever. Then removed the assembly by two screws that are forward to the unit and go upwards.
The insulation, sensor, and sensor cover are simply pulled down and off and the unit separated to removed the tray, and then insert the new tray. Proceed in reverse. Takes only a few minutes.

Replace Gasket on refrigerator door
6 of 10 people found this instruction helpful.
  • Curtis from DEMOPOLIS, AL
  • A Bit Difficult
  • 30 - 60 mins
  • Screw drivers
The replacement gasket does not have as strong a magnet as the original one. I removed the old one carefully so as not to cause more damage in case I have to put it back. Using Tongue suppressor I pushed new gasket into place and put a thin coating of protelem jelly on the gasket. I just have to make sure the door is closed each time to be sure of good seal.

Broken Guide Rail

This site was awesome! I was able to very quickly look up my refrigerator model, find the proper part number, and order the part. The only suggestion I would make is to update the cut sheet with a more clear version, it was a little difficult to make out the part number because the scan/drawing was fuzzy, but I was still able to make it out. Got the part in the mail very quickly and it was super easy to remove the old rail and install the new one. Take out the screws from the old one, remove the old rail, line up the holes, install the new one, and put back the screws. It's so nice to have a site like this to fine parts and order them! Too cool! Thank you so much!
