A few years ago I bought an old GEC fridge at auction, like these groovey smeg retro things in appearance. The fridge does work quite well despite being about 40 years old but had a sticker on it saying "do not use" with a fault description saying "02 high earth bonding" I discovered this sticker after having plugged it in and run it for a few hours and have not used it since. What does the sticker mean and is it something that can be easily fixed as I want to use this lovely old thing in my new kitchen. Thanks for any advice.
