Hisense ice maker displays E12 and stops; interior may be very cold or not cold enough depending on sensor fault.

Safety: Disconnect power before accessing internal panels.

• Locate the cabinet sensor: This sensor is usually mounted on an interior wall or near the air return grill.
• Inspect mounting: Ensure the sensor is properly clipped in place and not dangling or touching the evaporator directly.
• Test resistance: Disconnect the sensor and measure resistance with a multimeter. Compare to Hisense temperature/resistance chart. Replace if open, shorted, or far out of range.
• Check wiring and connector: Inspect the harness for cuts or pinched sections and ensure the connector at the PCB is secure.
• Replace sensor or PCB: Install a new cabinet NTC sensor if defective. If a known-good sensor still triggers E12, the main control board may need replacement.
