Glass on Oven Door Broke: Reasons, Prevention, and Repair

Home » Glass on Oven Door Broke: Reasons, Prevention, and Repair

The oven door is a vital component of any kitchen, providing a protective barrier while allowing you to monitor your culinary creations. However, the glass in oven doors can sometimes break, causing inconvenience and potential safety hazards. In this article, we’ll explore the reasons behind oven door glass breakage, preventive measures, and steps for repair if it does occur.

Why Does Oven Door Glass Break?

  1. Thermal Shock
    • Rapid temperature changes, such as setting a hot dish on the cool surface of the oven door glass when the door is open or exposing the door glass to cold water, can cause thermal shock. This sudden expansion or contraction of the glass can lead to fractures.
    • Prevention: Avoid drastic temperature changes by allowing the oven to cool gradually before cleaning and avoid placing frozen items inside the oven before they have a chance to thaw. Also, you should always avoid setting items on the open door glass even for a moment.
  2. Impact Damage
    • Accidental impacts from heavy pots, utensils, or other objects can cause cracks or shattering of the glass.
    • Prevention: Handle cookware with care, make sure oven racks are pushed completely inside the oven before closing the door, and avoid slamming the oven door shut.
  3. Manufacturing Defects
    • In rare cases, defects in the glass or the oven door assembly can lead to premature breakage.
    • Prevention: Inspect the oven door regularly for any signs of wear or damage, and handle your oven with care.

How to Prevent Oven Door Glass Breakage

  1. Use Proper Cookware
    • You should opt for cookware that is compatible with your oven and suitable for high temperatures. Avoid using glass or ceramic dishes with visible cracks or defects.
  2. Avoid Slamming
    • Gently close the oven door to prevent undue stress on the glass. Slamming the door can weaken the glass over time.
    • Make sure to push the oven racks and cookware completely inside the oven to prevent clashing against the oven door glass.
  3. Clean Carefully
    • Use mild, non-abrasive cleaners and soft cloths to clean the oven door glass. Avoid harsh chemicals or abrasive scrubbers that can scratch or weaken the glass.
  4. Monitor Temperature Changes
    • It’s common for oven door glass to shatter when the internal oven temperature is exposed to rapid cool temperatures due to thermal expansion causing stress because the heat is not evenly displaced, also known as thermal shock.
    • When baking bread using steam, professional bakers like Peter Reinhart will mention in their recipes to be careful when pouring water into hot pans to ensure the water will not splatter onto the oven glass door because this can potentially crack the glass.
    • Allow the oven to cool down before cleaning or exposing it to cold temperatures.
    • Similarly, avoid placing very cold dishes directly on a hot surface and hot dishes onto a cold surface to minimize thermal shock. This will also help prevent your expensive cookware from shattering and ruining your meal.

How to Repair Oven Door Glass

Remember that safety should always come first. Before attempting any repairs, ensure the oven is turned off and completely cool to prevent burns or further damage.

Evaluate the extent of the damage. If there is a chip, you must not use the oven until it is repaired. You do not want the chipped glass to create spiderwebbing faults and potentially shatter. If your glass is completely shattered, carefully remove the broken glass and locate any micro pieces of glass that may have fallen inside or outside the oven.

Do not use a regular vacuum to pick up glass shards as these can damage the parts inside the vacuum cleaner. On bagged vacuum cleaner models, shards of glass can tear open the bag. On bagless vacuum cleaner models, glass can damage or scratch the canister.

Safety cleaning tips:

  1. Wear closed-toed shoes and durable long pants to protect your feet and knees while working.
  2. Prevent animals or children from encountering the damaged glass until it is cleaned up.
  3. Wear cut-resistant gloves.
  4. Use a wet paper towel or masking tape to pick up glass shards. This is a safe and easy way to protect your hands and collect glass shards without being cut.
  5. Use a dedicated broom and dustpan to collect the glass. Make sure to shake the broom into a cardboard box or paper bag to dislodge any stray glass shards that may still be on the bristles of the broom.
  6. Put the glass into layers of newspaper or junk mail, then place the wrapped contents inside paper bags or a cardboard box. Plastic bags should be avoided as they tear more easily than paper bags or cardboard boxes.
  7. Use a flashlight to inspect the area for any remaining glass shards.

Next, you will want to replace the glass on the oven door. All ovens come with two glass oven door panels, an inner glass oven door panel, and an outer glass oven door panel. Some ovens come with three to four glass oven door panels. Go to and enter your model number to find the genuine OEM replacement part you need for your range or wall oven.

Inner Door Glass Replacement

Replacing the inner door glass on an oven involves a series of careful steps to ensure safety and proper installation. First, unplug the power cord or shut off the power supply to the oven to avoid any electrical hazards. Open the oven door fully and, if necessary, remove it by unlatching the hinges. Place the door on a soft, flat surface to prevent damage. Unscrew and remove the inner panel of the door to access the glass. Be aware you may need to uninstall the door handle first. Carefully take out the broken or old glass, ensuring to remove any debris or glass shards. Insert the new glass, making sure it fits securely within the frame. Reattach the inner panel by screwing it back in place, and replace and secure the handle if necessary, then reattach the oven door to the hinges if applicable. Finally, test the door to ensure it opens and closes smoothly before restoring the power supply.

Outer Door Glass Replacement

Replacing the outer door glass on an oven requires careful handling and precision. Again, before you begin, unplug the power cord or shut off the power supply to the oven to ensure safety. Open the oven door fully and, if possible, remove it by unlatching or unscrewing the hinges, then place the door on a cushioned, flat surface to prevent scratches or damage. Be aware, you may need to uninstall the door handle first as well as remove the inner door panel and glass to reach the outer door glass. Unscrew and remove the top and side trim pieces that hold the outer glass in place. Carefully lift out the damaged outer glass, being mindful of any sharp edges. Clean the door frame to remove any debris or old adhesive. Position the new outer glass into the frame, ensuring it aligns correctly. Reattach the trim pieces by screwing them back securely. Reinstall the inner door panel and door handle if necessary. If the door was removed, reattach it to the oven by aligning and securing the hinges. Finally, close the door and check for proper alignment and operation before reconnecting the power supply.
