My oven has stopped working

1. Open the oven door and remove the 2 screws at the side of the inner glass window 11cm above the hinges and lift off the door. Place it somewhere safe!
2. Remove the 4 screws that you can see nearest to the left and right edges of the oven with the door removed. These secure the oven to the kitchen unit.
3. Slide the oven forwards about 20cm out of the unit, being careful not to pull on the cable.
4. Each hinge is held in place by 2 screws at the side of the unit now exposed, about 18cm apart. Remove them and slide out the hinges. Reassembly is the reverse of the above.
5. Note that the hinges have no means of adjustment. If not working properly, renew them.

You can find the online at several sites, they will be universal however so you will have to know the diam. and how it connects etc, but I am sure you can find something that will work.

The hob is normally totally independent of the oven. What is actually working or not working on the oven? i.e. does the grill still work, is the clock OK and can you set it, or is everything totally dead?

Well, you can try STOVES and see what they will charge, and/or try espares. Once you have the part number, google that to see if anyone else can supply.
You may want to think about replacing both hinges and the springs at the same time, to ensure the door works/closes properly. Also, check the rubber seal round the door, then tend to become brittle when at the end of their service life, so it may pay to include that with the order as well.

sure repair it yourself, it is most likely the glow coil, $50 bucks and your good

I suspect this may have been happening for quite some time and you may never have noticed it. MANY ovens vent near one of the stove eyes. If you lift the cooktop for 'servicing', I bet you see the little vent. It is usually in the back right underneath the cooking surface. Check to make sure it is not blocked, clogged or has rusted out/off.
