Hi
Hoping someone out there is an expert with J&S System E-T warm air boilers.
Last year ours stopped working, after some reading up I changed the temperature sensor and the main circuit board, which got it all working nicely again.
In the last couple of weeks there has been a noisy clicking noise coming from the circuit board whenever the room thermostat turns it on or off.
Its not all the time, maybe 30% of the time but I'm concerned its about to fail.
It sounds like a relay switch flicking on and off.
Does anyone have a good idea what's going on and if its an easy enough job to do myself?
Like i said, I changed the circuit board myself so not afraid to have a go, even if I shouldn't?!
many thanks
