Camray 5 Oil Combi not switching off.

[Bigdons]

Can anyone help ?

My canray 5 will not stop running the central heating ! Especially if the wind is blowing ?!

Most of the time it is fine and when the internal thermostat clicks at temp in the house the burner and pump switsh themselves off !

But like tonight, if there is a breeze,.. or it just feels like it...... the thermostat in the house and the timer can go off, but the boiler keeps runing and heating the house.

Is it a thermostat in the boiler that needs sorting, motorised valve,... or somit else ?


Oh,. and the call for hot water works fine.

Cheers,

Check for a faulty frost stat, or a stuck motorised valve. Possibly could be a fault on the PCB with a stuck relay. Without following the circuit diagram it is impossible to say exactly where you problem is.
