Getting cool, hmmm now its cold... stopped sometime this afternoon.
When demand comes on the fan (and pumps) run fine, feeling outside by the flue there is a fair draft.
I'm pretty sure the quiet click by boiler controler I hear is the air pressure switch on OK but nothing else happens, no clicking of the ignition etc.
3 wires on pressure switch: more to the center is the live/brown?
two wires at top, white and orange.
The central wire showed live, only one at the top (white I think) indicates live with tester screwdriver.
Quite hard to get to (2, red) gas solenoids to test but I think NO lives on any of the 5 wires.
PCB looks ok, no scorches etc
Pressed the reset button - no change
Suggestions re good contacts (Bromley area)?
Suggestions what to check?
