Under counter freezer (Woodley RG5)

A few cosmetic blemishes and the top flap has been repaired. It works BUT I think the thermostat needs replacing as it doesn't always switch off when it should. A couple of times we've noticed it's not cold enough. Not warm enough to defrost food but not reliable. We ran it with a digital thermometer in so could keep an eye on it. A new thermostat is around £40. When replying please state when you can collect and your postcode.
