Electric cooker oven repair - Whats inside cooker oven and what are the components and parts

The model of cooker i am working on today is a Bush your may differ not a lot i can do about that but mostly of the part will be similar so use this as a guide not as a exact manual for your repair.

So this is a ceramic hob cooker with twin oven the bottom oven has one element and light bulb and is fan assisted.

The upper oven is a grill  / oven and has a element that does both but this is a single element version some do have a separate element for both grill and oven use.

So here are some photos of the outside of the cooker i am working on .

Now move onto the upper hob they are all different in the way you get into them and

infact this one is a terrible version as replacing the ceramic elements is very difficult to

realign them correctly .

so i first undo any retaining screws and all are different so cannot help you exactly on your model 

best to get the manual .

The underside of the hob unit the metal cover unscrews and the elements are them lose

to change but be aware this type are hard to refit as it can take ages to realign the elements correctly.

Quick peak into all the connections there are four elements on this one 

and a lot of wires 

these are the pins that need aligning on refitting looks easy but it can be 

very hard to align them all correctly i Tipex the tips of the and the holes 

so i know where they fit.

With the hob removed you can now access the switch panel here you can change switches and 

or thermostats.

Thermostats and switches , ensure you note and photo the wiring on the one you need

to replace.

you need to remove the screws from the front panel 

and lastly the lcd display and timer panel electronics pcb.
