got a hit on a different model and it says temp probe or main board
did see if it had a resitance value but no
try to see if its open circuit that would point to it bsing the probe as the board would need programming if that was the fault
also if you get it going a lot of these units do a self test procedure when you turn on the fan oven. when turned to fan oven the grill element is turned on and off in short bursts. only when the board detects a rise in temp does the main fan and element come on. it also means it wont start with the door off
fooled me completly the first one i got
