What Does Error E104 Mean?
The Neff Oven error E104 indicates a malfunction related to the temperature sensor, which may be caused by a short or open circuit. This fault affects the oven's ability to accurately measure cavity temperature, leading to failure in heating and potentially causing the internal fan to operate at high speed as a safety precaution. If this error persists, it may require inspection and repair of the temperature sensor circuit.
Common Symptoms:
- Error code E104 displayed on oven control panel
- Oven may stop heating due to inability to read temperature
- Internal fan may run at high speed as a safety measure
Possible Causes
- Temperature sensor fault (short or open circuit) (medium)
- Wiring issue between temperature sensor and control board (medium)
How to Fix Error E104
DIY Fix Power cycle and check basic conditions
- Turn the oven off and disconnect from power (unplug or switch off circuit breaker).
- Wait for at least 10–20 minutes to allow any residual charge to dissipate.
- Reconnect power and attempt to restart the oven to see if the error clears.
Technician Only Inspect and repair temperature sensor circuit
- Disconnect oven from mains power.
- Access the temperature sensor and its wiring harness inside the oven cavity.
- Visually inspect the sensor and wiring for damage, shorts, or loose connectors.
- Measure the sensor resistance with a multimeter and compare to manufacturer specifications.
- Replace the temperature sensor or repair wiring as needed.
- Reassemble and test the oven to confirm the error no longer appears.
Parts needed: Temperature sensor (e.g., PT1000/PT500), Wiring harness/connectors
- After power cycling, E104 persists on restart
- If the user is not comfortable accessing internal oven components
- If multimeter testing indicates abnormal sensor readings
