Hi guys,
Thank you for advice... I will check the cap.
The unit came with the house we bought in Ballarat, so I don't know if/when it stopped working and how...
I am not qualified electrician, I am only RF electronics engineer... with license to approve/oversee work like this (but not in Oz) so I will take that risk
I already rewired and sort out couple of strange things the previous owner (or tradesman) did..
