Ordered and dispatched.
The freezer defrost has helped slightly in that the fridge is now cold again. The warning light went off, but came back on again when I turned the freezer off to re-fit the rear panel.
Hopefully I’ll be able to get it fitted tonight. Also hope it comes with instructions as I’ve no idea how to remove the existing sensor, unless it’s a case of “Jam it anywhere in the evaporator that it’ll fit” 😀
Pete.
