My first fridge repair – a door hinge. I don’t normally do fridges, but the hinge broke while I was at my customer’s house and I offered to sort it out. It’s a built under Bosch KUR15A40GB/64. It’s sealed in by a hard fixed kick board, so no easy access to the back. The mains plug is accessible in the adjacent cupboard, possibly from an extension lead, but there is no earth continuity between the plug and fridge door.
Should the hinge be earthed, or is this part of the fridge cabinet designed to be double insulated?
