Whilst we were away we could not get the fridge to work as forgot the ramps and we were at a slight angel. I have just got home from Weymouth 165 mile drive had the fridge on battery to make sure that it worked. It did it froze everything in the ice part. Whilst unloading I heard a buzzing and traced it to the Moore Power should this be buzzing with the vehicle switched off? I have plugged the mains in. T
he only way to stop the buzzing was to turn off the circuit breaker. Is this right?
