Monogram ovens use the GE F-code system: F0 and F1 point to the control, F2 to an over-temperature condition usually from a drifted sensor, F3 and F4 to an open or shorted oven sensor, and F7 to a stuck button. A temperature-related code most often means the sensor.
As GE's luxury line, Monogram uses one of the industry's longest-established code schemes. The control constantly monitors the oven sensor and its own circuits; when a reading falls outside safe limits, it posts an F-code and often locks out. The most common practical codes, F2 and F3, both point to the oven temperature sensor, which drifts with age.
F2 typically means the oven exceeded its temperature limit, usually because the sensor read low and the control kept heating, or a relay stuck closed. F3 and F4 mean the sensor circuit itself is open or shorted. In both cases, testing the sensor resistance and the control relay confirms the fault, and replacing the sensor plus recalibrating restores accurate baking.
F0, F1, and F7 point to the control board and keypad, a stuck touch button or a control fault. A Monogram that shows an F2 or F3 and locks out is protecting itself from a bad reading, so repeated resetting is not the answer. Because Monogram rides the GE parts platform, sensors and controls are readily available and repairs are efficient.
Quick Reference
| Code | Meaning | Fix |
|---|---|---|
| F0 / F1 | Control or keypad | Replace control board |
| F2 | Over-temperature, sensor drift | Test sensor and relay |
| F3 / F4 | Open/shorted oven sensor | Replace the sensor |
| F7 | Stuck touch button | Service the keypad |
