Oven fan keeps cooling down process?

Hi! I have a Smeg SFP805AO oven where the fan keeps blowing, the light is green in the key indicating that the oven is too hot, door is locked, and is cooling down.

HOWEVER the oven is very much completely cooled down (been so for a month) and I can easily open the door.

The porblem started when I ran a pyrolysis program and the inner glass broke, and the fan kept blowing.

I have now replaced the broken glass, thermostat, AND the fan, but the problem is the same. Should I invest in a new motherboard or just give up?
