Listening to R. 4 the other day they mentioned that freezers §are rated (temp wise) to the area’s where they are sold. The jist of it was that with hotter weather some freezers would be struggling to maintain temperature and motors could burn out. Freezers in UK are not rated for extended high temperatures 40 deg c. , particularly when they are in external garages where temp’s can go way above external temperatures.
**. Keep a check if you have a fridge or freezer in the garage.
