Possible Causes
Failed oven temperature sensor (NTC), Shorted sensor wiring, Stuck relay on power board, Cooling fan failure in oven cavity
How to Fix / Troubleshooting
Safety first: Turn off the oven and allow it to cool. Disconnect power before accessing internal components.
User checks:
- Ensure oven vents are not blocked by foil or pans.
- Do not use aluminum foil to cover the entire oven base, as this can trap heat.
Technician checks:
- Measure resistance of the oven temperature sensor at room temperature and compare with Siemens specs.
- Inspect wiring from sensor to the oven control board.
- Check the oven cooling fan for operation during heating cycles.
- If the sensor and fan are OK, test the control board relays; replace the oven control module if relays are stuck.
