I have spoken to my Corgi guy (He's been ill & on a 2 day course tomorrow).
From what I have diagnosed from the flowchart (d`oh) on the back & his own thoughts from what I have described its the air pressure switch.
Does anyone have the part number for this spare\guide to cost?
OK its warm at the top & the "fan" noise is loudest up there.
My regular Corgi guy is probably playing cards ATM in the pub across the road, trying to see if there's anything I can do in advance.
Hi
I have a Potterton Puma (80\80e). Since last night it is currently not giving any heat from the CH & the HW runs for about 10 secs before going cold.
Whats been done so far.
Replaced main circuit board as I had the old one with broken mains power track (repaired)...
