Fuse? Check any on the unit as well. Any little lilghts that should
be on or blink as the remotes or wired switch are operated?

The Everest engineer has seen the door and has told me that they replace
the whole motor assembly, with two new remotes. At a cost of £1060,
which seemed to me extremely high.

What a total waste of resources, assuming that they go to the dump. I
rather expect them to go back, get repaired and be sold again "new"
units.

I also expect you got the door installed with a whacking great
"discount" provided you signed up there and then.

At £1060 I'd be having the covers of and fixing it myself. If it's
just "dead" I'd be looking at power supplies first and establishing
it has what it needs to live.
