I opened the door and turned the temp control down and let the oven cool. Once cool closed door and slowly incremented the thermostat knob up till I got a steady 199/201C reading.
I turned the oven off at the plug, opened the door and let it go cold. Once cold I closed the door left all the controls as is and turned it on at the wall, it returned to 199/201C and the light went out.
It is now cycling between 190 and 201c which should be close enough.
The outside control says it has been set at 150C, so this oven's internal temp control is 45-50C out of whack.
Those boolits I coated were therefore cooked at near 250C for 10/11 mins. No wonder they went darker than expected. They got that hot the coating is actually flaking on a few boolits, although it could be due to oil on those that are flaking, see Prior post regarding my Fondle Fetish that I had.
These coated ones will now be recycled and the process redone at the correct temperature.
