Re: Bosch HBN56M551B/10 fan & light not working
Hi, and welcome.
1, replace grill element
2, sounds like you need to replace circulation fan
3, you made sure you’ve used the correct replacement bulb sometimes the length can vary just slightly but enough to not make contact, failing that and knowing the bulb is correct and ok, I would be looking at the bulb holder.
I don’t know your skill level or competency, but, Might be wise to call an engineer because it will need striping down.
