Maybe it comes down to how many cycles is the compressor good for? If you think wearout is an issue, then off periods are good. Leaving it on with a fan in back will collect more dust...Turning it off is an inconvenience (condensation cleanup). Tomato Tomoto?
We fridge off, door ajar...esp if not using for a month+
