Monogram Range Error Code F-

The F- code is a prefix for a family of oven control system error codes on Monogram ranges. The full code includes a number after the F-, and that number identifies which specific system or component has triggered the fault. The code is generated by the electronic control board when it detects a condition outside normal operating parameters. You will need the complete code, including the number, to diagnose the exact cause.

The oven should not be operated while an active F- code is displayed. The control board has flagged a fault condition and may have interrupted normal operation to prevent damage or a safety hazard. Allow the oven to cool, perform the reset steps, and only resume cooking if the code does not return. If the code persists, stop using the oven and contact a qualified technician.

If the code clears after the recommended reset procedure, no technician visit is needed. However, if the code returns after both the knob reset and the 30-second power disconnect, the issue requires professional diagnosis. The specific number following the F- in the code helps a technician identify the faulty component quickly, so note the complete code before calling for service.

A reset will sometimes clear the F- code if the fault was caused by a transient power event rather than a hardware failure. The recommended reset procedure is to turn both the Oven Mode Selector and Temperature knobs to OFF, let the oven cool for one hour, and then try using it again. If the code returns, disconnect all power to the oven for 30 seconds and reconnect it. If the code appears a third time, the reset process is not sufficient and service is needed.

Repair costs vary depending on which component has failed and local labor rates. If the fault is a transient one that clears with a reset, there is no parts cost at all. Temperature sensor replacements tend to fall in a lower cost range, while control board or relay board replacements are more expensive, potentially ranging from a few hundred dollars to several hundred dollars including labor. Getting a diagnostic service call first is the best way to determine the actual cost before committing to a repair.
