Hi,
standard open vented system with 2 zone valves
boiler: Glow-worm Fuelsaver MKII
About 2hrs ago boiler tried to fire up but instead of one click there was a few short ones and it didn't fire up
Since then I've spent time trying to work out what's wrong and I'm 90% sure its the thermostat because it doesn't pass 24V from transformer to the gas valve. Now if I play with thermostat knob the boiler fires up but not every time.
I have found a replacement HERE but I don't know can I install it myself because of the copper wired temperature sensor that I presume goes somewhere into heat exchanger. Can I use the old one and just connect it to new thermostat?
If not can I try to recondition relay that's causing problem?
Any advice or suggestions are more than welcome as it looks like cold night and day tomorrow
