I have a Halstead Ace Combi-Boiler. The hot water works fine, but the central heating just will not come on at all.
For some reason, although there are controls on the actual boiler for the heating, it goes through a seperate thermostat and potterton control box beside the boiler. I have set the thermostat to max and made sure the control box is set to constant, but no luck.
On the bottom of the boiler is a lock-out reset switch. It's a red button and just seems to hang, when you press it it does nothing, but also doesn't feel like a button. It's like just lifting a piece of plastic, doesnt seem to engage anything if you understand me?
I have no intention of fixing this myself, i am just wondering if anyone has an idea of what the problem may be and what cost i am likely to be looking at to get this fixed?
