Hey Potty Man!

[ChrisR]

As you're visiting, can you help with this on behalf of a corgi out of netreach? Lynx 2, Electronic ignition. Problem is that it doesn't modulate on heating, though it does on HW. Eventually the boiler cuts off on overheat. Would a dud CH temp sensor cause this? Anything else?
Suggestions please?

Thanks for posting Chris. When we need help, no one comes to our aid. Maybe it is because the faults that we get are not run of the mill 'thermocouple-broke' type.

Am home now and will phone Potterton.
