We had a theory that electrical appliances don't like traveling. When we move house a bit over 6 years ago everything packed in within 6 months of us moving!

Oddest microwave incident we had was with an old one. We bought it off a friend that had it a few years. We kept it a few more and then gave it to our son for his first house. It had always worked fine. When plugged in at the lad's new house it kept tripping the breaker. Took the plug cover off (yes, it was that old) and it was wired wrong - neutral to earth and vice versa. Never bothered the old fuse box and thankfully we were never electrocuted! Made me realise the benefit of RCDs instead of the old wire fuses.
