I'd appreciate help with 2 things:
1) Confirmation that I've diagnosed the problem correctly
2) If I'm right that I need a new GCV, where do I get one?!
Hold the Start button in and press the Igniter button: the pilot lights.
Count to 20 (or 30) seconds, release the Start button, pilot goes out.
ALSO, sometimes whilst counting to 20, the pilot light goes out.
It's the last bit that's leading me to think the fault is inside the GCV and not a faulty thermocouple.
The 1976 manual says it's fitted with a Honeywell V4400A1017 GCV but neither Google, Honeywell or the HRPC PartsArena websites know that reference!
Has anyone ever fitted an alternative GCV to this range of boilers?
Any help would be much appreciated.
