Freezer displays E2 and may run continuously or not cool correctly.

Safety: Unplug the Hoover freezer before removing any internal panels. Edges of metal panels and evaporator fins can be sharp; wear cut-resistant gloves.

• Access the evaporator: Remove baskets and the rear internal panel of the freezer compartment to expose the evaporator coil. This panel is usually held by screws and plastic clips.
• Locate the evaporator NTC: The sensor is typically clipped to the evaporator tubing or embedded in a small plastic holder attached to the coil.
• Visual inspection: Check if the sensor has fallen away from the coil or is encased in heavy ice. If there is heavy ice, fully defrost the unit (leave unplugged with doors open and towels in place) before testing.
• Check wiring and connector: Follow the sensor wires to the connector. Look for corrosion, broken insulation, or stretched wires. Reseat the connector firmly.
• Measure resistance: With the freezer unplugged, disconnect the sensor and measure its resistance. Compare to the cabinet NTC characteristics; a reading of OL (open) or 0 Ω indicates failure.
• Check continuity to PCB: If accessible, measure resistance from the PCB connector back to the sensor to ensure the harness is intact.
• Replace the evaporator NTC: If readings are incorrect or intermittent, replace the evaporator temperature sensor (NTC) with the correct Hoover part. Clip it firmly back onto the evaporator tubing in the original position.
• Reassemble and test: Refit the evaporator cover, restore power, and monitor operation for several hours to confirm that E2 does not return.

Technician note: If the sensor and wiring are good, the main control board may be misreading the sensor and require professional replacement.
