The main causes: glass subjected to high stress
The door of an oven is usually made of tempered glass or borosilicate glass , two types of materials selected for their ability to withstand heat and impacts:
Soda-calcium tempered glass : The most common type, it withstands heat well but can be sensitive to sudden temperature changes.
Borosilicate glass : Less commonly used in domestic ovens, this glass is particularly robust against temperature variations.
However, cracks or breaks may occur due to:
Microscopic defects embedded in the glass, such as nickel sulfide inclusions.
Repeated exposure to extreme thermal cycles , especially when using the oven’s self-cleaning mode.
Behaviors to avoid: protecting the oven door
Although the glass used is strong, certain actions can compromise its resistance:
Do not overload the door : Avoid placing heavy objects, even temporarily, on the open door.
Caution when cleaning : Avoid abrasive sponges and harsh chemicals that can cause micro-cracks.
Preventing impacts : Do not hit the glass with dishes or utensils to avoid any breakage.
Avoid thermal shock : Never place a cold dish in a hot oven, nor a hot dish in a cold oven.

Tips and recommendations for maintaining your oven door
To ensure a long lifespan for your oven door, here are a few simple practices to adopt:
Clean gently : Use non-abrasive products and a soft sponge to preserve the glass surface.
Check the installation correctly : Make sure the door is properly aligned and the hinges are securely attached.
Reduce the use of self-cleaning : This mode generates very high temperatures that can weaken the glass.
Control the positioning of the dishes : Avoid utensils being in direct contact with the glass during cooking.
When should the door be repaired or replaced?
In case of visible cracks or chips, prompt action is necessary:
Repair without delay : Even a tiny crack can suddenly spread and cause a complete burst.
Call in a specialist : Never attempt to dismantle or replace the glass yourself, this represents a significant risk.
Conclusion
Your oven door is a crucial component that deserves special care to ensure safety and proper functioning. By following these simple tips, you minimize the risk of breakage while extending the life of your appliance. A well-maintained oven guarantees safer and more efficient cooking.
