A Class fridge freezer has a central cowl around the temp dial held in place with a cross head screw (hidden by a cap). Unscrew it and the cowl drops down. I just had to wiggle the light cover for it to work again.

What Claire said below. Small cross-head screwdriver required. helps if you are left handed!

There is a screw at the far end of the cover, unscrew that and it removes easily
