Bosch Range Error Code F160

Cooling fan Hall effect feedback not present (SIR

Bosch codesBosch range codes

Cooling fan Hall effect feedback not present (SIR: cooling fan motor failure or loose connections; FSR: display control faulty with incorrect model configuration).

First step from the service manual

SIR: In SERVICE mode, verify operation of cooling fan and feedback. Verify power to cooling fan; voltage = 60-120V. FSR: Verify that unit is an FSR and not an SIR (no fan in FSR). Return display control to BSH with note of error 160 in FSR.

What F160 means on a Bosch range

The F160 error code on a Bosch range indicates that the control board is not receiving Hall effect feedback from the cooling fan motor. The cooling fan Hall effect sensor is a small electronic component embedded in the fan assembly that generates a pulsed signal as the fan blades rotate. When the control board sends power to the fan and receives no return pulse signal, it interprets this as a fan failure and triggers F160. This feedback loop is critical because the cooling fan protects sensitive electronics in the range from heat damage during and after cooking cycles.

The diagnostic approach for F160 differs depending on the range configuration. SIR (slide-in range) models are equipped with a physical cooling fan, so the likely culprits are a failed fan motor, a wiring fault, or a loose connector between the fan and the control board. During service mode, the cooling fan circuit should receive between 60 and 120 volts AC. If voltage is confirmed at the fan but no feedback signal is returned, the fan motor itself is the likely failure point. If voltage is absent, the fault may lie upstream in the wiring harness or control board.

FSR (freestanding range) models do not have a cooling fan at all. If F160 appears on an FSR unit, the cause is almost certainly a misconfigured or incorrectly installed display control board, meaning the board was programmed for an SIR model and is expecting fan feedback that will never arrive. In this situation, the display control must be returned for reprogramming or replacement, with documentation noting the F160 error on an FSR unit. Correctly identifying which configuration the range uses is therefore the essential first step in any F160 diagnosis.

Common causes of F160

  1. 01

    Cooling fan motor failure

    Part replacement

    The fan motor itself has failed and is not spinning, so no Hall effect pulse signal is generated and returned to the control board. This is the most common hardware cause on SIR models and can be confirmed when voltage between 60 and 120V is present at the fan connector but the fan does not run.

  2. 02

    Loose or disconnected wiring to the cooling fan

    Wiring / connection

    A connector in the wiring harness between the cooling fan and the control board has come loose, interrupting both the power supply and the feedback signal. Inspecting the fan wiring connectors for secure seating and corrosion is an important early step on any SIR model showing F160.

  3. 03

    No voltage reaching the cooling fan

    Wiring / connection

    If the control board is not supplying the expected 60 to 120V to the fan, the motor cannot run and no feedback signal will be produced. This points to a wiring fault upstream of the fan or a possible control board output failure.

  4. 04

    Display control board misconfigured for wrong model type

    Part replacement

    On FSR (freestanding range) units, F160 typically means the display control board was programmed with SIR firmware and is expecting cooling fan feedback that does not exist. This is confirmed by verifying the unit is an FSR with no physical cooling fan installed.

  5. 05

    Failed Hall effect sensor in the fan assembly

    Part replacement

    Even if the fan motor spins, a failed Hall effect sensor within the fan assembly will produce no feedback pulse to the control board, triggering F160. This fault is specific to the sensor circuit rather than the motor windings and may require replacing the fan assembly as a unit.

Frequently asked questions about F160

What does F160 mean on a Bosch range?
F160 means the control board is not receiving the expected Hall effect feedback signal from the cooling fan motor. On slide-in range models, this points to a fan motor failure, a wiring problem, or missing voltage at the fan. On freestanding range models without a cooling fan, F160 indicates the display control board has been configured for the wrong model type and needs to be corrected.
Can I fix F160 on my Bosch range myself?
Diagnosing F160 requires entering the range's service mode and checking for voltage between 60 and 120V at the cooling fan connector, which involves working with live voltage and internal components. For safety reasons, this work is best handled by a qualified appliance technician. If the issue is simply a loose wiring connector rather than a failed motor or control board, an experienced DIYer may be able to reseat the connector after disconnecting power, but full diagnosis generally requires service tools and mode access.
Is it safe to use my Bosch range while F160 is displayed?
Operating the range with a non-functioning cooling fan carries a risk of heat buildup around sensitive electronic components, which can lead to additional failures or damage over time. It is advisable to limit use of the range and schedule a repair promptly. If F160 is appearing on a freestanding model due to a misconfigured control board, the underlying risk is still present because the electronics may not be operating within their intended parameters.
Will resetting the range clear the F160 error code?
A power reset by unplugging the range or turning off its circuit breaker may temporarily clear the F160 code, but the error will return if the underlying cause has not been resolved. If the cooling fan motor is failed, the Hall effect sensor is faulty, or a wiring connection is loose, the control board will detect the missing feedback signal again and re-trigger the fault. A reset alone is not a repair for this error code.
How much does it cost to repair a Bosch range F160 error?
Repair costs for F160 vary depending on the root cause. Reseating a loose connector is essentially a labor-only repair, while replacing a cooling fan motor typically adds parts costs on top of the service call fee. If the display control board requires replacement or return for reprogramming on an FSR model, costs will be higher. In general, expect to pay anywhere from $100 to $400 or more depending on the parts needed and local labor rates.
