Hi. My name is Chris & I own OvenFix - a small local company that specialises in Electric Oven Repairs. By the sounds of it either the thermostat is faulty or one of the heating elements has blown. If you still require a repair feel free to call me - we can run through a few steps & I can diagnose the fault over the phone for you. We are members of Trustatrader & strive to offer a 1st class service. Please see www.OvenFix.biz for full details or my direct number is 02086686850. Thanks.

We have a Zanussi built-in double oven that doesn't seem to reach the correct temperature. I have since invested in 2 decent oven thermometers and neither make the same reading however they do read between 30-50 degrees under what the oven claims it's temperature to be!
Is there anyone that any of you could recommend to come and take a look at it as I'm fed up of having to guess what temperature to set my oven to, and seemingly I can't get it above 200?!
