UC-15I Ice Maker Making Too Much Ice

Topics:

  • Undercounter Ice Maker UC-15I(P) producing too much ice, ice bin overflowing
  • Adjust or alter automatic shutoff to change how much ice is produced
  • What is the metal rod running along the top of UC-15I(P) ice bin for?
  • Why is the metal bar on the left side of a UC-15I(P) corroded, discolored, or water stained?
  • Bin clip, part #7013482, and bin thermostat
  • High altitude considerations for the UC-15I(P)

Cause:

  • Bin thermostat has failed or needs adjustment
  • Unit is missing bin thermostat clip

Troubleshooting:

First, verify the bin clip is installed on the bin thermostat and is hanging down approximately 1 inch.

  • The bin thermostat and clip are the metal rod and cover on the inside left front of the bin. Everything else is plastic.
  • The bin clip, part number 7013482, can be easily installed by slipping it onto the bin thermostat tube or metal tube found along the left wall of the bin.
  • If the bin clip is missing, contact a Factory Certified Parts Distributor to order a replacement.

Then, adjust the bin thermostat control, found behind the unit’s kickplate, to raise or lower the level of ice. To adjust:

  1. Remove the four screws attaching the kickplate to the unit, then remove the kickplate.
    • The bin thermostat is near the lower right corner.
  2. Turn the bin thermostat control to change the ice level.
    • Turn counterclockwise to decrease the level of ice.
    • Turn clockwise to increase the level of ice.
  3. Install the kickplate and the kickplate screws.
  4. Monitor the ice production.
  5. Allow 24 hours for the adjustment to take full effect.

If these steps do not resolve the issue, no further troubleshooting advice is available.  Contact Factory Certified Service to schedule an appointment for repair.

Answer:

Bin Thermostat Operation

The bin thermostat senses when the bin is full to prevent the unit from making more ice, and turns on ice production as the ice level lowers.

  • When the bin is full, the ice makes contact with the bin thermostat, cooling it. The thermostat then signals the ice maker to stop ice production.
  • As ice is used or melts, the ice level lowers and no longer makes contact with the bin thermostat. 

To check operation of the bin thermostat:

  • Place three ice cubes on the thermostat clip for about five minutes. Ice production should stop.
  • Remove the ice cubes. The ice maker should restart approximately five minutes after the cubes are removed.

Discoloration

It is normal to notice some discoloration or water staining of the bin thermostat, as water does splash onto the bin thermostat.

  • It is possible for a build-up of calcium or lime to occur.
  • This depends on the quality of the water supply source and the frequency of cleaning.
  • If desired, the bin thermostat can be wiped with a blue Scotch-Brite cleaning pad to wipe off any build-up.
