My potterton Profile Prima 80e was not firing up. I traced it to a faulty air pressue switch which I replaced. It will now work ok for a day or so, then stops working again, and when I check with my multimeter, the pressure switch has not reset.
I've removed the exhaust bend and checked the tubes and the fan which are all ok. There is a restrictor in the bottom tube to the pressure switch, which I can blow through (Just ! )
I now think I should replace this restrictor and both the red & clear tube to the switch, as the red tube has a bit of a kink in it, and I'm not sure about the restrictor.
What do you think of this idea ??
