Also called a duo valve. There is no fuse for it.
This is the state of mine on removal at MBS. It is indeed in a very inaccessible position against the bulkhead. Colin has a novel way of removing it!
Thank you for that, who is Colin?
The part from MB is only £32.84 so if you can help with a way to remove and fit I may give it a go.

Well I went to get the new valve, not very far away and on the way back the heater burst into life and came on and also turns off. Probably Malcolm's 'Give it a bash fix'. I'll keep the part as it may still again, which will probably be when it's so cold I won't want to be out there changing it
Worth the bash then, what ever would some member think reading this
