F111Bosch Oven — Bosch Oven F111 Error Code

F111 appears specifically during the self-clean cycle and indicates the oven has reached an unsafe temperature in the control or cooling zone, separate from the cavity itself. This is most often caused by a failed or weakened cooling fan that is supposed to protect the control panel electronics during the high-temperature self-clean process. Without adequate cooling, the area around the control board overheats and the safety circuit trips. A partially blocked cooling vent or a seized fan bearing can cause the same result.

Allow the oven to cool completely before doing anything. Check the cooling fan vents (usually on the top of the oven or behind the control panel) for blockage — grease or debris buildup can restrict airflow significantly. Restore power and listen for the cooling fan running immediately when the oven is switched on (most Bosch ovens run the cooling fan continuously when the oven is in use). If the fan is silent when it should be running, it has likely failed and needs to be replaced by a technician. Avoid self-clean until the fan is confirmed operational.
