Changing a Lamona 3502 oven heater coil?

Here's a typical element (Coil?)

Isolate the cooker supply first.

There will be 2 screws holding down the rectangular plate at the back and one more screw holding down the centre support. All screws should be accessible from the front.

The element should pull forward (CAREFULLY), drawing the 2 or 3 cables behind it.

Pull off the cable "faston" connectors (CAREFULLY - these need to be tight).

Reassembly is the reverse, but make sure you don't trap any cables under the rectangular plate when you put the element back into position.

You should be able to find typical videos on YouTube, with a bit of a search
