4 screws hold the fan cowl at the rear of the oven, remove them and remove the cowl to reveal the fan with the element coiled around it. Remove the single screw attaching the element clip on the rhs of the element. There are a further 2 screws either side of the element attachment point, remove these last. The element should be pulled towards you and then the three wires can be disconnected, make a note of where they are connected. Replacement is a reversal of the proceedure.
The main element on our oven has failed 3 times in 4 years so you need to get used to doing this.
