Has my Silavent CUR7003B Timer fan packed up?

The Fan in my bathroom started making a load noise but still worked then one day I pulled the light cord and it did not switch on with the light.

I have opened the cover and have removed fluff and noticed a burn patch on the small circuit board all wires are intact.
After trying without luck to get a sparky to even come out and have a look at it, I would like to know if I purchased the above unit which is a like for like or the next model up Silavent CUR7004B extractor fan do I just connect the wires or is there anything else that needs to be done. also where can I buy it from

Same problem

Moisture clearly drains down the large copper pins and short on the board.
Looks like a design flaw.
Northlogic Ltd that used to make the circuit boards for them has gone out of business (late 2016?).
So getting the, say £15, circuit board is now out of the question.

There is a timer board for sale on ebay

Silavent 7oo3B cost about £60-00 new - cheaper than a call out from a spark. Replace the old unit with new - connect wires like for like. Remember to isolate the supply beforehand. Good luck
