Sub-Zero Undercounter Refrigerator/Freezer with Ice Maker (UC-24CI) Does Not Make Ice
Topics:
- No ice production in Undercounter Refrigeration Series (UC) model
- Ice maker will not cycle on UC Undercounter product
- Ice maker does not work and no fault codes
Cause:
- Possible jammed ice cube
- Low water pressure
- Frozen ice maker fill tube
- Warm freezer temperature
- Water valve energized longer than fifteen seconds
Troubleshooting:
- After the unit is turned on, wait 24 hours for ice production. It may take this long to see ice cubes in the ice bin.
- Verify the ice maker is turned on. If the ice level arm is in the up position, the ice maker is turned off.
- To resume ice production, turn the unit off and push the arm down gently. The ice maker arm only moves an inch. See also, Ice Maker Control Arm Will Not Lower.
- Note: When the ice maker is turned on, water may not flow into it immediately.
- Make sure the ice bin is properly installed and is level and seated in place.
- Make sure the ice maker is free of obstructions or jammed ice cubes.
- It may be necessary to defrost the freezer to clear the ice maker. Refer to Manually Defrost a Sub-Zero for instructions.
- Make sure the water supply to the unit is turned on. Refer to Water Line Shut-Off Valve Location for details.
- Warm temperatures impact ice maker performance. Confirm the freezer temperature is at or below 5°F. Sub-Zero recommends 0°F freezer temperature.
- If the freezer temperature is higher than 5°F, see Warm Freezer Troubleshooting.
- Make sure the condenser is clean. See Undercounter Models Condenser Cleaning for instructions.
- If installed, verify the home inline water filter is not expired. See Inline Water Filters. See also, Sub-Zero Does Not Have a Water Filtration System.
- Confirm good water pressure to the unit. See How to Confirm Water Pressure.
- Make sure the ice maker water fill tube is not blocked. See Ice Maker Fill Tube Frozen.
- After freeing blockage, turn the unit off, then on again to reset.
- If ice production stops often with the use of a reverse osmosis system or well water, a pressure booster or regulator may improve performance. Contact the reverse osmosis provider or speak with a plumber for suggestions. See also, Sub-Zero with Reverse Osmosis Water System.
- After doing these steps, wait 24 hours for ice production to resume.
- If ice production does not resume after following these troubleshooting steps, service is needed to expertly diagnose and repair the unit. Contact Factory Certified Service to schedule an appointment for repair.
