I stumbled across your site while looking for a solution to an Ideal Classic NF260 boiler problem.
Our boiler is situated in the garage ... from inside the house you might never know there is a problem ... it heats the water, timed for 2 hours in a morning, and the radiators heat up when the timer kicks in.
We noticed the water was cooler than normal the other day and having had a seized fan on a couple of occasions assumed it had happened again ... normally a matter of lubricating the fan bearings and it would run trouble free for another year or so.
It wasn’t the fan.
On checking, the boiler is only running half it’s time.
It will start normally, run for just over a minute then stop for about a minute then start again only to stop again after the minute is up.
I timed this happening for 17 cycles. The off period is quite precise at around 57 seconds, and the running period about 1min 5 seconds.
I don’t know if these times are in keeping with the ignition detection system ... or is it something else?
Thank you for your help.
