Hello!
Our ageing combi is developing a fault. It either takes a long time to ignite, or fails to ignite at all. When it takes a long time, all the usual noises happen, several clicks and a fan, then normally where you'd hear the sound of gas burning, nothing for maybe 15s, then it lights. Or doesn't light, in which case the red light with a crossed out flame comes on and I have to reset the system to get it to light.
Is there anything I can do as an amateur, either to fix or at least to diagnose? I'm not totally naive - I have repeatedly changed the microswitch on the diverter over the years, and fitted an external controller - but I obviously don't want to go anywhere anything that could blow us up or gas us.
Many thanks. This baby is about 15 years old, I was hoping she'd make it to 20!
