Get really loud vibration from oven - especially when it is cooling down following cooking. Can sometimes stop the rattling if I 'hit' front panel with open hand, but problem recurs on next use. Have replaced fan assembly at rear of oven cavity. Is there another fan in the structure that I haven't yet found or is this the result of some resonant vibration in the oven panels? Drives me to distraction! Cannot seem to be able to find a detailed parts diagram to dismantle with confidence.

yes if the noise continues when you turn the oven off then it is the cooling fan causing the noise.this is in the top of the oven
