The central heating on my Range Powermax 140 bolier no longer works.
Having read the manual, I believe this could be due to three things:
1) The CH pump,
2) The cold start stat,
3) The room stat.
I've checked and there is no power getting to the pump, so I don't think the pump is a problem. Also, the spindal is free to move.
I've bridged the cold start stat and that doesn't solve it.
Also, I've bridged the room stat and that doesn't solve it.
On turning the room stat, we no longer hear the clicking sound of the relay. I bought a replacement and this hasn't fixed it. On checking the connections on the room stat, it doesn't appear that it is getting power from the boiler.
Does anyone know what the problem could be???
Alternatively, if anyone can recommend a plumber in the Bristol / Stoke Gifford area and approxiamte costs, this would be appreciated.
Regards,
Chris
