I have one of these inline exhaust fans for one of our bathrooms and it is powered by a standard electrical outlet. one day we smelled a Burnt Motor smell and then noticed this was no longer working. I plugged something else into the electrical outlet and confirmed the outlet was still functioning.
it would appear to be a simple replacement, The most difficult part would be mounting and reattaching the duct
just wanted to ask here to see what I would need to prepare
I believe I have 15 CM ducts in the bathroom. I can enter the roof cavity it's a bit dark but otherwise fine.
I can see the duct going into this fan which is next to a post (red). there is a strip of metal that curves around the fan holding it up. I have not examined this closely as I was in a hurry and it was very dark

do you know why it is mounted in this fashion?
my existing fan has more of a hump in the middle not like the photo above. I don't know what the difference is but it is a mirvac home so it's probably the lowest common denominator equipment
how do I choose which fan is the most suitable? It extracts into the ceiling cavity and the existing duct is there. it is a two Storey townhouse the bathroom is small and probably does not need to be super strong
Do all inline fans come with a standard plug you can plug into any electrical outlet?
