Freezer temperature is too warm or too cold and the display shows E2

Safety first: Unplug the appliance before removing panels or handling wiring.

Step 1 – Access the freezer thermistor:

• Empty the upper shelves of the freezer to gain access to the rear or side wall.
• Locate a small plastic cover or grill; remove it to expose the sensor.

Step 2 – Inspect for ice and damage:

• Check if the sensor is encased in ice; if so, allow the unit to defrost (power off, doors open) for several hours or use a hair dryer on low, keeping it moving to avoid melting plastic.
• Look for damaged insulation or pulled wires.

Step 3 – Test the thermistor:

• Disconnect the sensor from its connector.
• Measure resistance with a multimeter at freezer temperature (e.g., around -18°C the resistance will be significantly higher than at room temperature).
• An open circuit or 0 Ω indicates a defective sensor.

Step 4 – Replace the sensor:

• Purchase a Brandt‑compatible freezer thermistor.
• Remove the old sensor from its clip or bracket.
• Install the new sensor in the same location and route the wiring as originally installed.
• Reconnect the plug, restore power, and monitor if E2 disappears after a short run period.
