how can i fix my creda europa main oven?

so the ovens giving out some heat,

sounds like the thermostat has failed,that's the dial on the control fascia you regulate the temp with,

the whole oven will have to come out if its intagrated,(model no would of helped),

remove it from the unit and isolate the power,

remove the top panel and pull the dial off the thermostat switch,

the rest is straight forward,

before you remove any wiring, look on the stat by each terminal for numbers,and make a note of their numbers and their relation to the colours of the wiring.
I say this because your replacement stat maybe different but all the terminals are numbered, and you can relate to your note of coloured wire for each number,.
