Hi I have just fitted a lofra electric cooker pxv66amfr to the existing socket cable from my old tricity cooker. Everything works and although the oven thermostat light go out when they reach temperature everything I cook needs a higher temp and longer than what it should take. The ovens don't seem to get as hot as they should. Could the fact that I have connected the new cooker to the old cable have anything to do with reducing the oven temperatures or could it be my imagination. Thanks for any advice
