leenia, thanks - I'll do that.

It was not mounted near the floor, but at about 4ft 6in, so pentane, unless released close to it, (it was just round the corner from the top of the heat exchanger) should not have reached it. Pentane is written somewhere about the fridge. I can't believe they would leave a flammable gas in the insulting foam.

Whatever the gas was, it needs controlled removal, as in the case of CFCs.

No colour changes of late, anyway.

I am waiting for the new fridge. Delivery window from 7am to 2pm. I am five minutes from the shop, so got up REALLY early. But last time I had a delivery at 5 past 7, it didn't involve a removal, so of course they will come at 5 to 2. But I can't be sure. So I can't do anything....
