E6 is displayed and the unit may stop mid‑cycle; fan may run but ice production is inconsistent or absent.

Safety first: Disconnect power before accessing internal components.

• Locate ambient sensor: The ambient thermistor is typically mounted near the air intake or on the interior wall away from the evaporator. Refer to the service diagram if available.
• Visual inspection: Check for moisture damage, corrosion, or broken wires at the sensor head and connector.
• Measure resistance: Disconnect the sensor and measure its resistance at room temperature. Compare to Magic Chef specifications. A reading of 0 Ω or OL indicates a short or open sensor.
• Check harness routing: Ensure the harness is not pinched between panels or cut by sharp metal edges.
• Replace sensor: If readings are out of range or the sensor is damaged, install a new ambient thermistor. Secure it in the same location and orientation as the original.
• Reset and test: Reconnect power and run a full cycle to confirm E6 is cleared and the unit operates normally.
