neff bi422n0gb/03 oven

neff bi422n0gb/03 oven. the cooling fan runs continuously. I have changed the thermal limiter but it still runs on. this oven has a small control module on the top of the oven would this be the problem? any pointers would be appreciated as I have never had this fault on one of these ovens.
thanks Darren

can see that board

have you checked to see if the relay is shorted

not sure what it does as Bosch tech is hard to get but i think i would pull one wire off at a time to see if it stops

Good suggestion about pulling wires off. I’ve looked at the parts drawings on the Bosch site and it’s the only thing that stands out which may be the problem. I’ll see if I can get back and pull some wires. Thanks for the suggestion Dave
