Question 1

the 'ICE FULL' light is on but the basket isn't full, it just stopped. how do i get it going again?

Accepted Answer

DIAGNOSISThe 'ICE FULL' indicator is triggered by an infrared sensor inside the ice basket. If this light is on but the basket isn't full, the sensor is likely blocked by frost, ice shavings, or dust, or is being tricked by bright light. A less common cause is a temporary control board error that needs a reset. FIX Unplug the Antarctic Star Hzb 12 B from the wall outlet. Remove the ice basket and empty any ice. Inspect the small infrared sensor window (usually a plastic lens) on the side wall of the basket compartment. Use a dry, soft cloth to gently clean the sensor window and the area around it, removing any frost or debris. Plug the unit back in. With the empty basket correctly placed inside, press and hold the 'Select' button on the control panel for 5 seconds until you hear a beep. This manual override will force the icemaker to run for approximately 10 more cycles, clearing the 'ICE FULL' signal. IF THAT DIDN'T WORKIf the light returns after the override cycles, the problem is environmental or the sensor itself. Ensure the unit is not in direct sunlight or where bright reflections can hit the basket area, as this confuses the infrared sensor. Move it to a shadier location. If the problem persists, the sensor may be faulty; you can often continue using the unit by manually resetting it with the 'Select' button whenever the light comes on incorrectly. HEADS UPAlways unplug the appliance before cleaning any internal components. The manual override is a temporary diagnostic step; if the sensor is defective, the icemaker may eventually stop producing ice altogether and require professional service.

Question 2

just moved my ice maker inside from the garage, it won't turn on. did i break it?

Accepted Answer

DIAGNOSIS This is almost certainly not a breakage issue. The Antarctic Star Hzb 12 B ice maker has a built-in low-temperature cut-off sensor designed to prevent operation when the unit's internal components are too cold. Moving it from a cold garage into a warm house causes condensation to form, and the internal temperature needs to stabilize before the safety system will allow it to power on. FIX Leave the ice maker unplugged and with its door closed in its new indoor location for a minimum of 4-6 hours, or ideally overnight. This allows the entire unit, especially the internal electronics and compressor, to acclimate fully to room temperature and for any internal condensation to evaporate. After the waiting period, plug the unit's 3-prong plug directly into a dedicated, properly grounded wall outlet. Do not use a power strip or a multi-plug adapter. Press the power button. The unit should now start, and you should hear the compressor engage and see indicator lights. IF THAT DIDN'T WORK First, verify your power source. Try a different known-good outlet. Ensure you are not using an extension cord, as they can cause voltage drop; if you absolutely must, use a heavy-duty cord rated for at least 14 AWG gauge and 1875 watts. If the unit still shows no signs of life, check that no circuit breaker has tripped in your home's electrical panel. Finally, inspect the unit's power cord for any damage that may have occurred during the move. HEADS UP Always allow the ice maker to sit unplugged for several hours after any significant temperature change (moving from cold to warm or warm to cold) to protect the compressor. This is a normal protective feature, not a defect.

Question 3

my ice cubes keep sticking together in a big clump, how do i stop that?

Accepted Answer

DIAGNOSIS Your ice cubes are fusing together because they are being made in a super-cold environment with high humidity, causing them to partially melt and then re-freeze into a solid block. This is a common issue with the Antarctic Star HZB 12 B, often triggered by the machine being in a very cold room or using water that is too cold to begin with. FIX First, adjust the machine's settings and environment: Press the "Ice Size" button to select the small cube setting. Smaller cubes freeze faster and have less surface area to stick together. Ensure the machine is in a room where the ambient temperature is above 60°F (15°C). If it's in a cold basement or garage, moving it to a warmer spot is crucial. Check the water in the internal tank. It should be between 40°F and 90°F. If the water feels very cold, empty the tank and refill it with room-temperature tap water. IF THAT DIDN'T WORK If clumping persists, perform a cleaning cycle to ensure the system isn't compromised by mineral buildup or a faulty sensor. Mix a solution of white vinegar and water (1:1 ratio), run it through a cleaning cycle, and then run several cycles with fresh water to rinse. Also, make sure the ice basket is not overfilled; remove ice every 24 hours to prevent old cubes from acting as glue for new ones. HEADS UP Never use hot water or force apart stuck ice cubes with sharp objects, as this can damage the ice tray or internal components. If the room is consistently below 60°F, the machine may not operate correctly, and clumping will likely recur.

Question 4

my ice maker says 'ADD WATER' but i just filled it, it's not making ice. help?

Accepted Answer

DIAGNOSISThe 'ADD WATER' alert on your Antarctic Star HZB-12B persists even after filling because the unit's water level sensor isn't detecting sufficient water. This can happen if the water level is slightly below the internal sensor probe, if there's an airlock in the water line, or if the water pump itself is momentarily blocked or needs a reset. FIXFirst, ensure the unit is properly filled and reset. Follow these steps:Press the ON/OFF button to turn the ice maker off. Open the lid and verify the water level is exactly at or just above the MAX line on the water tank. Do not overfill. Close the lid securely and press the ON/OFF button to restart the unit. After restart, the compressor needs time to stabilize. Wait at least 3-5 minutes before expecting ice production to begin. You should hear the water pump cycle and water flowing. IF THAT DIDN'T WORKIf the alert remains, try these solutions:Check for Air Locks: Tilt the unit slightly (with it off) to help any trapped air in the pump or supply tube escape. Inspect the Water Inlet: Ensure the water inlet screen or tube inside the tank isn't blocked by mineral deposits or debris. Manual Reset: Unplug the ice maker for 2 minutes, then plug it back in and restart. This can clear a temporary electronic fault. Water Quality: Using heavily mineralized water can cause scaling that impedes the pump or sensor. Use distilled or filtered water. HEADS UPAlways use the unit on a level surface. An unlevel ice maker can cause inaccurate water level readings. Never add water while the unit is running, as this can damage the pump or cause improper cycling.
