Oven door springs will wear over time and can break or become damaged. If these springs break then shutting your oven door can be more than a little problematic. If these springs break then you will need to have them replaced; professionally replacing them can be very expensive which is why most people will resort to trying to complete the job themselves.
This is actually a very simple project, but that doesn't mean it's without its dangers. Oven doors can quite easily trap fingers which can cause pain, discomfort and sometimes even serious injury. Make sure you keep your fingers free at all times. This project is actually a very uncommon project, and as long as you spend time doing it properly there's no reason why you will ever need to do it again in the future.
Step 1 - Removing the Door
The first thing that you will need to do is remove the door from your cooker. If the oven is inside a cabinet then this might first need to be pulled out so that you can access the door. Most doors will simply lift off the oven when it's opened slightly. However there are some doors which have a small retaining lever which first needs to be pressed down in order to release the door so that it can be lifted off. Once the door is removed you should set it aside safely so that it is somewhere out of the way.
Step 2 - Dismantling the Door
If your door hinge is broken or damaged then the door will need to be dismantled so that you can access the hinge itself. This will take some time to do right but is worth doing properly. Remember where all the components go so that you can assemble the door properly again when required.
On some cookers you won't need to dismantle the door to access the springs. On a range cooker for example you should be able to access the springs by opening access panels inside the walls of the oven. If you're working on a built in cooker then you might need to remove it from your cabinet to access the springs.
Step 3 - Replacing the Springs
The hinges can now be replaced on the doors. Make sure that you replace both hinges even if only one has gone. This is a lot of work to dismantle the door and adding an extra hinge won't break the bank. There is also a good chance that this hinge is wearing out already which is why you should consider replacing it at the same time.
Step 4 - Don't Struggle in Silence
This is a very difficult project for any amateur to undertake if you've never had any experience before. If you do find it difficult then consider hiring a professional to help you.
