I have a Sharp Combi Microwave oven (R-959MA) which has always given good service. However, recently when using it on Convection only, as a normal oven, I felt the food was under-cooked. On checking with an oven thermometer I discovered that when it was set to 200c the oven thermometer only registered 143c and crept very slowly up to 150C eventually.! Is this normal?
Regards and thanks in advance
