Digital New World freezer shows E1 and interior temperature is too warm, compressor does not start or starts briefly then stops.

Safety first: Unplug the freezer from the mains before removing any panels or touching wiring. Use insulated tools and avoid working on live circuits.

Steps to check and address E1 (cabinet sensor):

• 1. Power reset: Unplug the freezer for 5 minutes, then plug it back in. If E1 returns immediately, continue with diagnosis.
• 2. Locate the cabinet NTC sensor: On most New World upright and chest freezers with digital controls, the cabinet sensor is clipped behind the inner liner, often near the top or mid‑section, with two thin wires leading to the control area. Access is usually from inside the cabinet behind a small plastic cover or channel.
• 3. Inspect wiring and connector: Check the sensor wires from the cabinet to the main control PCB (usually behind the top front display or rear control box). Look for cuts, pinches, rodent damage, or corrosion at the plug. Reseat the connector firmly.
• 4. Test the sensor: With the unit unplugged, disconnect the sensor from the PCB and measure its resistance with a multimeter. At room temperature (around 20–25°C), most New World NTC sensors read between 4–15 kΩ (exact value varies by model). If it reads open circuit (OL) or near 0 Ω, the sensor is faulty.
• 5. Compare to service chart if available: If you have the model’s resistance/temperature chart, compare your reading. A large deviation indicates a bad sensor.
• 6. Replace the sensor if defective: Order a compatible New World cabinet NTC temperature sensor using the model number. Route the new sensor along the original path, avoiding sharp bends and hot components. Clip it securely in place and reconnect to the PCB.
• 7. Check the PCB if sensor tests OK: If the sensor and wiring are good but E1 persists, the temperature input circuit on the main control PCB may be faulty. Inspect for burnt components or corrosion. Replacement of the PCB is usually required and is best done by a qualified technician.

When to call a professional: If you are not comfortable testing resistance or accessing the control board, or if a new sensor does not clear the error, contact an appliance technician.
