Ideal Concord CXA40 no ignition

[popeye2755]

Hi all, wondering if someone could shed some light! A friend of mine (RGI) asked me to have a look at this boiler, as his staff had decided to throw PCBs at it! The fault occured after a power cut. The boiler turns on, the pumps start, but no ignition sequence. It's had one Aqua(?) pcb, and two ignition pcbs, symptons still remain. After checking a few things, I decided to meter the Flame Sensor, using a Fluke set to Ohms, between the ignition PCB and Earth. The boiler then went through its ignition sequence and fired up correctly. I then found that by directly earthing the Flame Sensor, I could also get the boiler to fire up. Ideal Technical suggested an earthing issue, but I Meggered it all, no fault found. We also extracted the burners and checked/Meggered the ignitor and Flame Sensor, all OK. Any suggestions???

Not wishing to be rude -no offence intended,
What are your Qualifications that entitle you to dismantle a Gas Appliance?

I wasn't, I was with an RGI, as stated in the first post...

Working on those parts of a boiler should be done by an RGI.

Questions about those aspects should be asked in the CC part of this web site.

I doubt that very much.

Popeye, in your original post you clearly state that an "RGI Friend asked YOU to look at the boiler" - in this industry "LOOK" is taken to mean Repair,
I was mearly asking what your Qualifications were (Electrician perhaps?)

I am baffled as to why a RGI with employees would ask a "mate" with no qualifications to repair a boiler that they had be unable to do (it's only an Ideal CX after all!
