I have a ideal classic rs40 boiler which no longer responds to heating commands. the boiler fires up no problem for hot water, but nothing happens when central heating is requested. the honeywell control panel seems to be ok, and i have changed the wall mounted thermostat as a precaution. I am guessing its the boiler control thermostat box which is at fault, but my knowledge is pretty basic. would appreciate any advice, thanks dean.
