AMICA GC-0620 Gas Hob: Thermocouple Replacement & Glass Plate Removal Without Detaching Panel

AMICA GC-0620 gas hob, thermocouple defective. The flame goes out after releasing the knob so probably a thermocouple to replace, but I do not know how to remove the glass plate to get inside. After removing the torch crown and unscrewing the two screws, you can remove the torch ring. Some of the screws fixing the rings are corroded and I will have to bore. I can't afford to pull out the entire disc and take it apart "in the workshop" because it is still used, hence my question - will it be possible to remove the glass without removing the glass without removing the panel from the top?

Hello
It seems to me that the idea of molding is not the best. In Amice, the problem often lies in the thermocouple-valve bad contact, just bend the thermocouple plug.

Actually, there is another thermocouple as I thought. Sorry for the incorrect entry

Thanks for the hint what to unscrew. However, I pulled the disc out of the counter, turned it up. I moved the thermocouple from another burner to make sure it was a thermocouple, not a valve, for example. Thermocouple to be replaced.
