Oven shows E2 and heating stops or never starts; fan may still run.

Safety first: Disconnect mains power before opening any panels.

Steps to check:

• Access the oven temperature sensor as described for E1 (rear upper cavity area).
• Inspect the sensor cable along its route to the rear of the oven. Look for crushed insulation where it passes through metal panels or near the fan housing.
• Disconnect the sensor from the harness and measure resistance with a multimeter. A reading near 0 Ω indicates a shorted sensor.
• If the sensor measures correctly at room temperature, check the harness for continuity to ground (one probe on each wire, the other on the oven chassis). Any continuity indicates a short to earth; reroute or replace the harness.
• Dry any moisture in the connector area and apply contact cleaner if corrosion is present.
• If wiring and sensor are good but E2 persists, the main control board sensor circuit may be damaged and require replacement.

Warning: Avoid bending the sensor sharply; it can be damaged internally. If in doubt, replace the sensor as a set with the harness.
