New World freezer shows E3 and the display temperature is inaccurate or does not change even when the interior warms or cools.

Safety: Unplug the appliance before removing the control panel or display housing.

How to address E3 (ambient sensor):

• 1. Locate the ambient sensor: On many New World freezers with digital displays, the ambient sensor is positioned near the control panel or behind the front fascia to sense room temperature. It is a small probe or plastic‑encased sensor with two wires.
• 2. Remove the control panel cover: Carefully unclip or unscrew the display/control housing. Avoid pulling on the wiring.
• 3. Inspect the sensor and wiring: Look for corrosion on the connector, broken insulation, or signs of moisture ingress. Reseat the connector to the main PCB.
• 4. Test the sensor: With the freezer unplugged, disconnect the sensor and measure resistance at room temperature. Compare to the expected NTC range (often several kΩ). An open or shorted reading indicates failure.
• 5. Replace if faulty: Fit a new New World ambient NTC sensor of the correct type. Route the wires away from sharp edges and resecure the sensor in its original location.
• 6. Check PCB if sensor is OK: If the sensor tests correctly but E3 persists, the main control PCB may be defective. Inspect for burnt tracks or components. Replacement is usually required.
• 7. Reassemble and test: Refit the control panel, restore power, and verify that E3 clears and the display responds to temperature changes.

Tip: A faulty ambient sensor can cause incorrect compressor run times, leading to over‑freezing or warming, so address this promptly.
