My DF came round today and helped me with some jobs. While he was here he moved my refridgerator so I could clean under/behind it. I always thought you were supposed to turn off a fridge and had to leave it to stand for a certain amount of time for chemicals to settle etc, so I'd been putting the job off. He said no I didn't if you're just dragging it a short distance, he does it all the time at home - so he didn't unplug it, just dragged it forward and to the side. It wasn't lifted and was upright the whole time. He pushed it back in after and I've continued to use it. Feeling a bit nervous about it now - is this OK to do?
