Kenmore Range Error Code F3

F3 means the electronic oven control has detected a fault condition. The control board monitors its own circuits and connected components, and when it receives a signal it cannot accept, it displays F3 and stops normal operation. The fault could be in the control board itself, the oven temperature sensor, or the wiring between them.

You should not attempt to use the oven while F3 is displayed. The electronic oven control has detected a fault and may have disabled heating as a safety measure. Using the oven in this state could result in no heat, uncontrolled heat, or further damage to components. The cooktop burners on a gas range may still function independently, but confirm this carefully and avoid the oven until the fault is diagnosed.

Cost depends on the failed component. An oven temperature sensor is a relatively inexpensive part, typically ranging from $20 to $60, and is a manageable DIY repair for someone comfortable with basic appliance work. An electronic oven control board is more expensive, usually $100 to $250 or more depending on the model, plus labor if you use a technician. A service call to diagnose and repair the fault generally runs $100 to $200 in labor alone, separate from parts cost.

Start by pressing the CLEAR pad to stop the beeping and clear the display, then try programming the oven again. If F3 does not return, the fault was likely a temporary glitch. If F3 comes back, record the code and contact a qualified service technician. A technician will check the oven temperature sensor resistance and inspect the wiring harness before concluding the electronic oven control board needs replacement.

Pressing CLEAR resolves the code if the fault was caused by a transient power event or a one-time software error in the electronic oven control. If an underlying hardware problem exists, such as a failing temperature sensor or damaged control board, F3 will return after you attempt to use the oven again. Recurring F3 codes after clearing require hands-on diagnosis.
