The hinges on my oven have failed to adequately hold the door shut several times. The first time was when the oven was about 5 years old. The last time was last week. The replacement hinges lasted exactly one day. They were fine when installed but failed to hold the door shut after I used the oven at 350 degrees to roast something for one and a half hours.

I'd really appreciate if someone could help me determine the cause for these failures. The oven is a built-in with a microwave above it and will be pretty expensive to replace.

Thanks.
