I have taken the door off the oven but how do I get the hinge into the oven section with spring loaded so tight?

Grill door is controlled by a pair of complex spring-loaded hinges and it seems the springs aren't doing the job - this might be because the hinges are tight, which would be a matter of lubrication, or because the springs are weak or broken.

The hinges usually aren't easy to access so it is best to try lubrication first by spraying with something like WD-40 fitted with a straw so it can reach into the apertures and then work the door for a couple of minutes to see if there is an improvement.
Be aware the propellant is highly flammable but it does disperse quite quickly.

If there is no improvement, the hinges will need replacing.

There is a powerful spring in the hinge, and if your oven is like mine, it has pulled the part that goes into the body of the oven, tight to the door. This spring is powerful enough to break fingers, so be careful. When I have had this problem, I have used chopsticks or a wooden wedge to hold the hinge part open in order to get it into the oven. Next time, look for some catches in the hinge mechanism that you can set, before you pull the door off, to stop the hinge from snapping closed.

Hi Elspeth:
Don't know what make or model you are dealing with, but from personal experience, here's what I dealt with.
- Oven door is mounted on spring loaded hinges. That's what keeps it in the closed position.
- To remove the door, it has to be fully opened, then lifted from close to the hinges, and slid out.
- To put the door back on, the hinges have to be in the "door open" position. Since they are spring loaded this can be tricky getting them into position.
- It's easier with a helper, one on each side....... slide the hinge legs into the slots. You'll need to lift the door slightly towards the closed position to allow the hinge legs to engage in the secure or latched position.
Hope this helps.
Cheers.

i just had a similar problem .the door would fall and i had to lift the top of my door hinge to close it .I found that the pin on the door hinge spring had fall.en out . I installed it back and now it works the way it should.the spring should feel tight with no movement.

If it is a drop down door with hinges on the bootom of the oven door, then it is likely to be weak door hinge springs, the usual solution is to replace both hinges.
If it is a swing open door, then the problem is related to a worn or broken door catch, or worn striker pin.

Hello- Many ovens use spring-loaded hinges to carry the weight of the door. Over time, these springs weaken or the hinge gets bent just enough to not fully close door. The door gasket can also become flat and stiff, compounding problem. Any small gap releases heated air, and oven will not heat up properly. Replacing the door springs should solve problem.- Thanks -Ed

Oven door hinges are not adjustable, assuming you have fitted the door back correctly, and it is still not closing properly, then the only solution is to replace the door hinges.

One of both of the springs are probably off or broken. Slide it out and inspect the hinges and springs which are at the bottom of the door. The springs hook to the hinge and the base of the oven farther back. You may have to remove the side cover.

These hinges are now obsolete and you cannot get them anywhere. The poblem with this type of hinge is not with weak springs or anything like that, it is with the pivot pin in the door hinge. Follow these instructions and it will not cost you anything for the repair.
It is best to remove the oven from the housing. Remove both sides of the oven panels, you have to remove the top first, then the sides (remove about 20 screws all together). Support the bottom oven door first by tying a bit of string between the bottom and top oven door hand rails. This will stop the door falling down when you remove the springs. unhook the springs and the door will just slide out. (Use a loop of string attached to the back end of the spring to pull it from its holes.)
Dismantle the door by removing the screws. You will probably find that the the hinge pivot pins have come away from the U shaped hinge bracket. The secret is to make sure that these are fixed firm back into the bracket. What I did was to nip the U hinge bracket in a vice, (or use pliers) so that the pin will now protude slightly each side of the bracket. This allows more surface bearing area so the pin will not pull itself out of the hinge. To further make sure, I glued the ends of the pin with epoxy resin.
Then reassemble.
My door now feels like a new one even though it is 15 years old.

This is a relatively easy fix however you will need to remove the door and it is heavy!

Start by opening the door completely and engage the small "locks" that are at the base of the hinge. This will ensure that the spring loaded hinges do not "spring open" when you remove the door. You then will need to remove the hinges from the door via a series of phillips head screws that hold the hinge assembly in place. The new hinges must be "preloaded" into the Open position using a vise or some means of holding the hinge in place while you use a small section of pipe to provide leverage needed to open the hinge so that the Locks can be engaged.

Once the new hinges are "pre-loaded" and the locks are engaged, you can reverse the procedure to re-install the hinges into the door and re-install the door.

Good luck!!
