Check the fuse under the fridge and it was bad. Replaced the fuse and it blew again(i thought these were resettable fuses)

Replaced the big heavy transformer and the lights worked...but only for a few hours and then the fuse blew again.

Sounds like a short somewhere in that light circuit.

Does anyone know if the thermostat light sensor is in that circuit or what else it could be?
