What Does Error F30 Mean?

The Bosch oven error F30 indicates a malfunction in the upper oven temperature sensor, often resulting in the oven failing to heat properly. This error may be accompanied by unusual smells when the oven is powered on. A short circuit in the sensor can cause this issue, leading to an error display and operational failures during cooking or preheating.

Common Symptoms:

  • Oven fails to heat or operate normally when attempting to cook or preheat
  • Error code F30 appears on the display when the oven is powered on

Possible Causes

  • Temperature sensor shorted (medium)
  • Wiring fault between sensor and control board (medium)
  • Control board fault (when sensor and wiring test normal) (low)

How to Fix Error F30

DIY Fix Basic checks before servicing

  1. Power off the oven and disconnect from mains power
  2. Check for any obvious signs of damage to the sensor wiring that are visible without disassembly
  3. If comfortable, visually inspect connection points for corrosion or loose plugs

Technician Only Diagnose and repair sensor circuit

  1. Disconnect oven power
  2. Access the oven temperature sensor (typically behind the oven interior back panel)
  3. Measure sensor resistance at room temperature
  4. If shorted, replace the temperature sensor
  5. Inspect wiring harness for shorts, breaks, or loose terminals and repair/replace as needed
  6. If sensor and wiring test good, test and replace the oven control PCB if necessary

Parts needed: Oven temperature sensor, Wiring harness, Control PCB (if necessary)

🛑 When to Call a Pro:
  • If unable to safely access internal components
  • If multimeter resistance readings are inconclusive or outside expected ranges
  • If error persists after sensor and wiring checks
