Refrigerator display shows E0 and cooling performance is reduced or intermittent

Safety first: Unplug the refrigerator from the mains before removing any panels or touching wiring. Do not work on live circuits.

Steps to check and address E0:

• 1. Power reset: Unplug the unit for 5–10 minutes, then plug back in. If E0 clears and does not return, it may have been a transient fault.
• 2. Locate the refrigerator sensor: The fridge NTC is usually clipped to the liner wall behind a small plastic cover or embedded in the rear wall of the fresh-food compartment. Remove shelves as needed and gently pry off the cover.
• 3. Inspect wiring and connector: Check for broken, pinched, or chewed wires. Ensure the sensor plug is firmly seated and not corroded. Reseat the connector at both the sensor and the main control board (usually behind the top or rear panel).
• 4. Test the sensor (for skilled users with a multimeter): With power disconnected, unplug the sensor and measure resistance across its two leads. Typical NTC values are around 5–20 kΩ at room temperature (exact value depends on model). An infinite reading indicates an open sensor; near 0 Ω indicates a shorted sensor.
• 5. Replace if faulty: If resistance is out of range or the sensor is physically damaged, replace the refrigerator NTC with the correct Bompani-compatible part. Route the new sensor along the original path and secure it away from moving parts or sharp edges.
• 6. Check the control board: If a known-good sensor still triggers E0, the main control board sensor input may be defective. Visual inspection for burnt components or corrosion can confirm suspicion, but board replacement is typically required.

When to call a technician: If you are not comfortable testing resistance or accessing the control board, or if replacing the sensor does not clear the error, contact a qualified refrigerator technician.
