My exploding glass door was on a Whirlpool double oven which they have refused to do anything about as it was one month over the 2 year warranty - the poblem seems to be that the handle is attached directly to the glass so possible the glass is already stressed and when it was cooling down after use just shutting the door caused it to disintegrate into tiny shards

If you are in Canada there is a government run organisation called TSSA regulates gas fired appliances. They would be interested in hearing about your story.

SOURCE: Oven Door Exploded

This fault has occurred on a number of these ovens and I've seen it happen occasionally on other makes and models.

The explosion is spectacular, but is actually due to a safety feature as all modern ovens which use glass doors must use toughened glass. This is heat-treated glass which is resistant to most knocks, but when it does break it shatters into lots of small granules instead of sharp edged shards.

In use, heat makes everything on the oven expand a little and afterwards everything cools down and returns to normal size. The problem is that the glass and metals do not expand or contract at the same rate and so there's always the chance that the differential expansion between the glass door and the metal hinges can put enough stress on the door to make it shatter. The engineers who designed your oven knew this and will have tried to ensure that the hinge design could cope, but it may be that they didn't do well enough.

The other possibility is that the door has a manufacturing fault: when toughened glass is manufactured the glass gets a lot of stress built into it (that's why it seems to explode when it breaks). After the glass has cooled down in the factory every one is supposed to undergo a couple of simple automated tests which will either cause the glass to immediately shatter or will cause it to be returned to the ovens to have the excess stresses removed. Sometimes these tests are not fully effective at identifying the "bad apples".

I'd strongly advise you to contact the manufacturer of your oven as the door should not fail in normal use even beyond the warranty period. What you have suggests a design or manufacturing fault and you may be offered a free repair without admission of liability.
