Freezer alarm sounds, temperature fluctuates widely, display may show unrealistic readings

Safety first: Unplug the freezer before removing any external covers or trims.

Steps:

• Locate ambient sensor: On some Hotpoint freezers, an ambient sensor is located behind the front grille, near the condenser, or in the control housing to monitor room temperature.
• Inspect sensor: Look for a small plastic probe with two wires. Ensure it is not hanging loose or touching hot components.
• Test resistance: Disconnect the sensor and measure resistance at room temperature. Compare to expected NTC values; open or short readings indicate failure.
• Check harness: Inspect the wiring from the sensor back to the main control board for damage or loose connectors.
• Replace sensor: Install a new OEM Hotpoint ambient NTC sensor, routing wires away from hot or moving parts.
• Reset and test: Restore power, clear any alarms, and monitor temperature stability over 24 hours.
