70 minutes into a 2 hr self clean cycle, F2 error (Oven Over Temp).

I cannot confirm, but the oven itself does not appear to be over 990*F.
Lock circuitry appears to operating properly (locks when it's supposed to, unlocks when cool)
Sensor circuit reads 1048 ohms at room temp, 2450 ohms when the fault occurs (spec is 1100 and 2600). These are at the ECR connector, so no issue with high resistance in the sensor wiring or connectors.

Component compartment (where all the electronics, cooling fan, lock and switches are) reads 215*F when the fault occurs. I was not able to confirm if the Thermal Limit Switch was open or closed, but all behavior is that the switch has opened--alarm sounds until compartment temp drops to 190*F. Switch specs are to open at 225*F and close at 190*F...we're close but does the component compartment get so hot during cleaning that is a 10*F shift in the switch is enough to cause a fault? Anyone know the design spec on temperature in the component compartment during self cleaning?

Thanks for any insight into this (before I just go change the TLS)
