Baxi combi boiler fault

[johnk]

My Baxi combi boiler is acting peculiar, it keeps cutting out and starting up again when the heating is switched on . When it cuts out the ''fault on central heating'' light is lit. Is the central heating temperature sensor faulty?
Thanks
John

it really could be any number of things, could be the ch temp sensor but could also be poor circulation due to a faulty pump, you really need to call out an engineer as they are so complicated.
