What to do if Sub-Zero UC-15I is not working?
- H
  Heather LaraJul 31, 2025
  If your Sub-Zero ice maker isn't working, consider the following: * First, make sure that the ambient temperature is correct. * Verify that the ice maker has electrical power. Check the fuse or circuit breaker, ensure the unit is properly plugged into a functioning outlet, and inspect the wiring. * Check the control board fuse and replace it if it's open. * If the transformer isn't outputting power, replace it. If the control board light doesn't energize, replace the control board. * For a faulty control panel, replace the wire harness or the control panel board. * Replace a defective bin thermostat. * For UC-15IP and UC-15IPO models, repair or replace a bad drain hose.

Why is my Sub-Zero Ice Maker producing ice slowly?
- A
  amandabooneAug 5, 2025
  Several factors can contribute to slow or low ice production in your Sub-Zero ice maker: * Consider heavy ice consumption, improper ambient temperatures, and improper water temperatures. * Check for poor airflow through the condenser by looking for obstructions in the vents, cleaning the condenser, and inspecting the condenser fan blade and motor. * Ensure the bin drain isn't restricted. * Check and replace the water filter if it is clogged. * Inspect the water trough for leaks and the standpipe position, repositioning or replacing parts as needed. * Address any water inlet valve faults by cleaning the screens, repairing loose wiring, or replacing the valve.

  David ClementsAug 10, 2025
  If your Sub-Zero ice maker is making ice, but the cubes aren't releasing, here's what you can check: * Check the hot gas valve or solenoid for loose wiring or a faulty solenoid coil. Also, check the operation of the hot gas valve; if it's stuck, replace the valve and drier. * Inspect the liquid line thermistor for disconnections, open circuits, or misreadings. * Check for power at the control board to the hot gas valve during the harvest cycle; if no power is present, replace the board.

Why are Sub-Zero UC-15I cubes shallow or white?
- C
  cadamsAug 15, 2025
  If your Sub-Zero ice maker produces shallow, incomplete, or white cubes: * Ensure there's enough water in the water trough. Check for kinks or restrictions in the water supply line, replace the water filter if partially clogged, clean the screens in the water valve, repair any loose wiring to the water valve, and inspect the trough and standpipe for leaks or positioning issues.
