Bosch Range Error Code F113

F113 on a Bosch range means the oven temperature reached a runaway condition, approaching 950°F, while the door latch was in the locked position. The fault points specifically to one or more cycle relays on the power board being stuck in the closed position, causing the heating elements to run without shutting off. This typically occurs during or after a self-clean cycle and is treated as a critical safety fault.

Resetting the breaker or cycling power may temporarily clear the error display, but it will not fix the underlying problem. If a relay on the power board is physically welded shut, the fault condition will return and uncontrolled heating can resume. The faulty power board must be diagnosed and replaced before the oven is considered safe to operate.

Repair costs vary depending on which components have failed. A replacement power board for a Bosch range typically costs between $150 and $350 for the part alone, with labor adding another $100 to $200 depending on your area and the service provider. If additional components like the temperature sensor or door latch assembly also need replacement, total costs could range from $250 to $600 or more.

No, the oven should not be used while F113 is active or unresolved. A stuck relay on the power board can cause the heating elements to run without control, creating a serious fire hazard and potential damage to the appliance. If the fault appeared during a self-clean cycle, allow the oven to cool completely before inspecting anything, and verify the circuit breaker status before proceeding.

The first step is to check whether the range's double-pole circuit breaker has tripped and reset it if needed. After the oven has cooled completely, the power board should be inspected for relay failure, which typically requires replacing the board. The oven temperature sensor and door latch assembly should also be tested to rule out contributing faults. Given the high-temperature nature of this fault, professional diagnosis is strongly recommended.
