Some people fill you with confidence. Others, not so much. The John Lewis delivery chaps turned up again to install the new ovens. This chap was far more inspiring than the chap who bottled out last time. It took them about an hour, but they got both of the ovens installed and did some simple testing. They took away the old ovens, packed up their tools and departed.
First job was to fire up the oven and let any lacquers or solvents burn off. The Gorse Fox followed the instructions and set the timer, temperature, and mode. He retired to the study. There was a click and everything went quiet. The RCD had blown. Somewhere they had done something wrong and the circuits had tripped. The Gorse Fox phoned his electrician. A bit of basic problem determination isolated the problem to the Grid Switch. This meant that it was the wiring to the Combi-Oven that was at fault. Isolated, now everything else is working ok. The electrician, however, cannot get to us until Friday.
Oh well, it was never going to be easy.
