We have often talked about How to Replace an Oven Element - I mean it is one thing ordering a new part for your cooker but you are going to have to know how to go about changing the element before you start. If you have never done this before then you are going to have to take time out and think about it. I hopefully we can give you a head start here.
Firstly I am trusting you have order the correct part from our online catalogue of Replacement Elements Use the Search facility if you need to and ask questions in the forums. If you need to know your model number then try looking inside the door possibly between the hinge area. There is a foil label with the model number printed on it.
Having now done that we need to isolate the oven at the cooker point. Now look inside the main oven and remove the oven shelves. at the back of the oven is a wall plate covering the fan and fan element. Four screws and you should be able to lift it out. The circular fan element is secured at the terminal plate with at least one screw and at it's periphery on the opposite end with another screw through the tab.
Remove the element from it's position carefull not to pull on it as the terminal wires are still connected. There should be enough wire length to allow you to pull the element free just enough to disconnect the terminal wires. If you can do that then just wrap the ends with a little insulating tape to prevent the wires from falling thorugh the holes to the back.
If there is not enough length on the wires to do that last bit then I'm afraid you need access to the back of the oven. Assuming everything is fine you can go ahead and replace the element with the new one. Checking that the terminal wires are safely fitted to the terminal tags on the element you can then mount the lement back in to place and secure it with the correct screws.
No need to replace the back plate at this stage becaus we are going to test the element works and that the thermostat switches the lement in and out when you expect it to.
With the door open turn the elemnt on and set it to the hottest temperature. Wait for it to go cherry red so it can burn the newness of it. It will smoke a little so perhaps a window open. Then let it cool for a whie and check the thermsotat then replace the back plate and restore the oven back to service.
Job done and well done if you made it this far.
