Bosch Oven Error Code F32
F32 is the double-oven counterpart of F31: the lower cavity's temperature sensor is reading open, shorted or out of range, so the control shuts the lower oven down. Sensor and wiring checks mirror the upper oven's.
Common causes
- Lower oven temperature sensor failed
- Open or short circuit in the lower sensor wiring
- Loose connector at the power board sensor header
- Control board sensor circuit failed
What to check, in order
- Note the code and reset the oven at the breaker for a minute; if F32 returns as soon as a lower-oven mode starts, the fault is present, not a glitch.
- Inspect the probe on the back wall of the lower cavity; clean it and check it is firmly mounted.
- With power off, follow the sensor wires as far as they are accessible and look for pinching against the chassis or a partly unplugged connector.
- Measure the sensor if you can: about 1,080 ohms at room temperature is normal; open or near-zero means replacement.
- A good sensor and wiring with a returning code points to the control board — a technician job.
Clear the code and test
- Fix what the checks above found first. Clearing the code without fixing the cause only brings it back.
- Plug the appliance back in and restore its water supply if it has one.
- Run the shortest programme and watch the point where the code appeared before.
- If the programme finishes with no code, the fault is cleared. If the code returns, write it down before calling a technician — it speeds up the diagnosis.
When to call a professional
Most cases are solved by the checks above. Book a technician if any of these apply:
- The code comes back after you have run the checks and a test cycle.
- You smell burning, see sparks or scorch marks, or the breaker trips.
- Water is leaking and you cannot stop it at the tap.
- The fix needs panels opened beyond what your manual describes, or a part tested with a meter, and you are not set up for that.
When you call, give the brand, the code F32, your model number (on a label inside the door or on the back) and the checks you already ran. It shortens the visit.

Parts are model-specific. Find your model number first — usually on a label inside the door, on the door frame or on the back — and match the part to that number before ordering.
