    Hi all,
    We recently moved house that has a rayburn 400kpf. There's a couple of issues I'd like to try and resolve. Firstly when turning the Rayburn on from cold, it runs for 2-3mins then cuts off as tho upto temp. Move the temp dial down then up it starts again. But only for a minute before it cuts off again. We have to keep turning the dial up and down to get it up to temperature. I've changed the temp stat but the problem persists. Secondly. Should the powerflu outside continuously run while the mains are turned on. It never stops on 24/7. Is this correct?

    Hope someone can help!

    Hi, no unfortunately not. Was told it had been serviced in the summer. But nothing to prove. It works fine just that it cuts out all of the time. As stated. Not Lockout. Just as tho it has reached temp.

    It is just a cooker. Not central heating.
