Sometimes, oven doors may shatter due to manufacturing defects. During the tempering process, if the glass isn’t treated correctly, it may have imperfections that make it more prone to breaking. Tiny chips, scratches, or internal flaws can weaken the glass over time. Even the smallest imperfection can create a weak spot, making it vulnerable to breaking under thermal stress.
4. Improper Installation or Alignment
An oven door that isn’t properly aligned can put extra stress on the glass. When you open or close the door, the glass may hit the metal frame unevenly, which can create pressure points. Over time, this pressure can build up and cause the glass to shatter.
If your oven door doesn’t seem to be closing smoothly or makes unusual noises when opened or closed, it may be misaligned, which could increase the risk of the glass breaking.
5. Accidental Damage
Everyday wear and tear can take a toll on your oven door. Accidental damage—like hitting the door with a heavy object, dropping a pot or pan, or slamming the door—can create weak spots in the glass that may not cause an immediate break but can shatter later. Once the glass has been damaged, even slightly, it becomes more susceptible to future breaks.
6. Nickel Sulfide Inclusions
Nickel sulfide inclusions are microscopic imperfections that can form inside tempered glass during the manufacturing process. These inclusions can expand and contract with temperature changes, causing internal stress in the glass. Though rare, these inclusions can cause the glass to break spontaneously, even when the oven is not in use.
How to Prevent Oven Doors from Shattering
While oven door shattering is rare, there are several ways to reduce the risk and keep your kitchen safe. Following a few simple precautions can help maintain the integrity of the glass and prevent unexpected breaks.
1. Avoid Rapid Temperature Changes
One of the easiest ways to prevent your oven door from shattering is to avoid rapid temperature changes. When you’re finished using your oven, try not to open the door immediately if it’s at a high temperature. Instead, allow the oven to cool down gradually before opening the door.
Additionally, avoid placing cold items, like frozen foods, directly onto the oven’s hot glass surface, as this can create thermal shock.
2. Inspect for Damage Regularly
