Monogram Range F6 Error: Analog-to-digital converter failure
The F6 error code on a GE Monogram range indicates a failure in the analog-to-digital converter (ADC) circuit on the control board. The ADC is responsible for translating analog sensor signals — such as oven temperature readings — into digital values the microprocessor can act on. When this circuit malfunctions, the control board loses the ability to accurately read sensor inputs and shuts down cooking functions as a precaution.

Answer to continue safely
Is it safe to keep using?
No. Do not use the range while the F6 code is active. The ADC failure means the control board cannot accurately monitor oven temperature, creating a risk of uncontrolled overheating.
Can I reset the code?
No. A power-cycle clears the display, but the code will return if the ADC circuit on the control board has physically failed. Persistent F6 requires board replacement.
When to stop immediately?
Stop if you notice: Stop using the range immediately if the F6 code reappears within minutes of a power reset., Stop if you detect a burning smell from the control panel area while the range is energized..
Symptoms You May Notice
Oven does not heat or stops heating mid-cycle despite the display appearing normal.
F6 fault code appears on the control panel, accompanied by a repeating alert tone.
Temperature readings on the display are erratic, frozen, or show implausibly high or low values.
Control board accepts inputs but cooking programs fail to execute correctly or abort early.
Possible Causes
Failed ADC circuit on the main control board — the converter chip itself has burned out or developed an open circuit.
Requires ProfessionalDamaged ribbon cable or connector between the control board and the sensor harness, corrupting the analog signal before it reaches the ADC.
Requires ProfessionalPower surge that damaged the control board electronics, including the ADC section.
Requires ProfessionalSafe Checks You Can Do
-
1
Power-cycle the range
Turn off the range at the circuit breaker or unplug it and wait 60 seconds before restoring power. An F6 code caused by a transient voltage event may clear after a full reset.
Wait a full minute to allow control board capacitors to discharge completely before restoring power.

Inspect the control panel for visible damage
With the range unplugged, examine the control panel area for burn marks, discoloration, or a smell of burnt electronics that would indicate board-level damage.
Do not attempt to open the control board housing — high-voltage components inside can retain a charge even when unplugged.
When to Call a Professional
Contact a qualified technician if:
- F6 returns immediately after every power reset, confirming a hardware fault on the control board rather than a transient event.
- Visible burn marks or a burnt odor from the control board area indicate the board must be replaced by a certified technician.
