What F131 means on a Bosch range

The F131 error code on a Bosch range indicates that the temperature probe (also referred to as a meat probe or oven probe) has not been properly calibrated or is failing to meet calibration standards during active use. The fault is detected specifically when the probe is engaged in a cooking program, and the control board allows a 20-second window before logging and displaying the fault. This timing threshold suggests the board is monitoring probe signal consistency and will only trigger the error if the out-of-calibration condition persists beyond that window, filtering out brief signal fluctuations.

The temperature probe system works by sending a resistance-based signal to the oven control board, which interprets that resistance as a corresponding temperature reading. When the probe's resistance output falls outside the expected calibration range for any given temperature, the board cannot accurately track the food's internal temperature. This can occur due to a damaged probe tip, a failing probe cable, or a poor connection at the probe jack inside the oven cavity.

Calibration faults like F131 are distinct from open or short circuit faults. The probe may still be functioning electrically but delivering inaccurate readings. This makes physical inspection of the probe, its cable sheath, and the probe receptacle jack critical first steps. Corrosion or food debris inside the probe jack port is a common and often overlooked contributor to this type of fault.

Common causes of F131

  1. 01

    Damaged or worn temperature probe

    Part replacement

    Physical damage to the probe tip or cable sheath can cause inaccurate resistance readings. Inspect the probe for kinks, burns, or cracks along the cable and at the tip.

  2. 02

    Contaminated or corroded probe jack

    Wiring / connection

    Food residue, grease, or corrosion inside the probe receptacle port in the oven cavity can interfere with the electrical connection and skew the signal. Clean the jack carefully with a dry cloth or compressed air.

  3. 03

    Loose or intermittent probe connection

    Wiring / connection

    If the probe is not fully seated in the oven's probe jack, the contact may be intermittent and trigger the 20-second fault. Remove and firmly reinsert the probe to verify a secure connection.

  4. 04

    Faulty probe jack receptacle

    Part replacement

    The internal probe jack mounted inside the oven cavity can degrade over time due to heat cycling. A damaged receptacle may fail to maintain consistent contact even with a known-good probe.

  5. 05

    Oven control board fault

    Part replacement

    If the probe and jack both test correctly and the error persists, the control board's probe monitoring circuit may be misreading the incoming signal. This is the least common cause and typically identified after other components are ruled out.

Frequently asked questions about F131

What does F131 mean on a Bosch range?
F131 on a Bosch range means the temperature probe is not calibrated or is not reading within acceptable parameters during a probe-based cooking program. The oven control board monitors the probe signal continuously and logs this fault if the calibration issue persists for more than 20 seconds. The error prevents accurate probe-guided cooking until the underlying issue is corrected.
Can I fix the F131 error myself without calling a technician?
In many cases, yes. Start by removing the temperature probe, inspecting it for visible damage, and cleaning the probe jack port inside the oven cavity. Reinsert the probe firmly and run a probe cooking program to see if the fault returns. If the probe itself is damaged, replacing it is a straightforward repair that most homeowners can do without professional help.
Will resetting the range clear the F131 error code?
A reset, such as cutting power to the range for several minutes, may temporarily clear the F131 code. However, because the fault is triggered during active probe use, it will return if the underlying calibration or connection problem is not corrected. A reset alone is not a fix, only a diagnostic step to confirm whether the fault is persistent.
Is it safe to use my Bosch range while F131 is displayed?
Standard oven baking and broiling functions that do not use the temperature probe are generally not affected by F131. However, any cooking program that relies on the probe for temperature monitoring will not function correctly, which could lead to undercooked food. Avoid using probe-dependent cooking modes until the fault is resolved.
How much does it cost to repair an F131 error on a Bosch range?
Repair costs vary depending on the faulty component. A replacement temperature probe typically costs between $20 and $60 for the part. A probe jack receptacle replacement may run between $30 and $80 in parts. If the control board is at fault, parts and labor costs can range from $150 to $400 or more depending on your location and service provider.
