# Monogram oven error code F3

### What F3 means, in the maker’s own words

The manufacturer’s table gives this as the oven sensor needing replacement. It is the open side of the sensor circuit — the control has lost its connection to the thing that tells it how hot the cavity is.

### Where this code actually appears

On the control panel, and usually with a sound. Monogram describes their refrigerator codes as flashing green on the display and typically accompanied by a beeping, and the range, microwave and dishwasher tables all describe codes you can read from the front of the appliance. That is the opposite of some makes, where the number is written into a hidden log and never shown — here, if something is wrong, the appliance generally tells you. Photograph what it says before cutting the power, because a reset erases it and the code is most of the diagnosis.

### Which machines this one applies to

Monogram professional ranges and wall ovens. Monogram says plainly on their own range and oven table that they cannot list every code for every model past and present, so a code missing from their table is not proof that your appliance cannot raise it — and a code in it is not proof that yours can. The model number settles it.

### What to do about it

- Note what the oven was doing. This very often appears during or just after a self-clean cycle, which is the hardest thing the cavity ever does.
- The sensor is measured against its published resistance curve at a known temperature rather than replaced on the strength of the code.
- The harness and the connector are measured with it. A good sensor reporting through a corroded connector fails identically, and replacing the sensor fixes it for about a month.
- The calibration is checked afterwards against a reference thermometer.

### Where this goes next

The job this usually becomes is [oven sensor and calibration service](/services/oven-sensor-and-calibration-service/), and every one of those pages carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call [(305) 614-3572](tel:+13056143572) and describe what the display is doing before booking anything.
