The first range I received in 2016 had an F9 code (lock switch problem during oven cleaning cycle) and the exterior, knobs and handle especially, were hazardous to touch. The oven sat unused for 3 months while it was being 'rebuilt' by an uncaring GE repairman. I finally managed to reach someone at GE Monogram who agreed that there was nothing more to replace and he swapped it for a new range in January 2017.
I don't run the clean cycle often but Spring 2020 started a new saga. Besides the F9 code, the gas burners also wouldn't light, AND temps of the knobs recorded at 375 degrees! The ignition switches were fine: eventually all burners came back on. Appliance repairman said there have Never been reports of such an issue, must be a coincidence. (Can clear the F9 code but would have liked the cleaning cycle to reach Half of the minimum 3-hour programmed). Tried cleaning in January 2021: had the same problem with gas burners (re-lighted on 7th day), so it's no longer a coincidence.
Used a different appliance repair company for the lock switch replacement done on 3/31/21. Tried the cleaning cycle on 4/6/21: F9 code appeared with about an hour to go of 3 hours programmed. Cleared it in about 90 minutes after cool down and circuit breaker off; happily, the gas burners still work. The exterior reached over 165 degrees.
Thousands spent on this Garbage and there is no recourse. When I called GE service number about it, I was advised they could send Their tech out for $99 to diagnose: already been told by 2 appliance repairmen that they'd checked with GE and were told "never heard of such a thing".
