I'm having some trouble with my oven.
It appears to be putting out heat through the top set of vents in this picture, there are two wide vents at the top.
I know that all ovens vent some heat but the heat coming out of these vents seems excessive and appears to be preventing the oven from maintaining temperature. The oven has recently started venting more heat from these vents. Other than calling an electrician who will charge me to tell me I should keep an eye on it is there a way to tell what the problem is and fix it myself.
This is a picture of the oven.
