Mr. Appliance experts explain what to do if a glass stovetop cracks. Using a stove with cracked glass may incur serious risks, including:

A glass stovetop is not just a piece of glass: It's a precisely engineered heating element that relies on a perfectly sealed, structurally sound surface to function safely. Breaking that seal sets a domino effect in motion, putting both the appliance and your safety at risk.
In this article, Mr. Appliance® expert Stuart Pyburn explains why you should never use a broken appliance, regardless of the size of the crack.
Why Can’t I Use a Cracked Glass Stove?
It’s tempting to ignore a hairline fracture in your stovetop glass, especially if the burners are still working. But before you decide to “just be careful” and continue using the range, it's critical to understand that this small crack is a significant and escalating hazard.
Stuart Pyburn, a Mr. Appliance expert with over 36 years in the appliance industry, explains that aside from the immediate danger to yourself and your family, “you could damage the burners under the glass.” Instead, you should immediately unplug a stove with a cracked glass top and “don’t try to clean it up yourself.” Instead, contact a trusted appliance repair professional for a glass stovetop repair estimate.
Electrical and fire risks
The most immediate and severe danger posed by a cracked glass stove is the risk of electrical shorting and fire. A glass cooktop's surface acts as a protective barrier, keeping liquids, food, and cleaning agents away from the delicate electrical components and heating elements underneath. Once a crack forms, that barrier is compromised.
Water from a boiling pot, a splash of oil from a frying pan, or even a simple countertop wipe-down can introduce liquid into the crack that may come into direct contact with the live wires and circuitry below.
Likewise, the heating elements are now exposed and unprotected, meaning any food debris or flammable material that makes its way into the crack can easily ignite, turning a kitchen appliance into a dangerous fire hazard.
Shattered glass
Glass stovetops are made from a type of ceramic glass that is designed to withstand high temperatures and rapid temperature changes. However, this is only true as long as the structural integrity remains intact. A crack, no matter how small, fundamentally compromises this integrity.
When you use a burner near a crack, the glass experiences thermal stress. The area around the crack heats up and expands, while the adjacent, cooler parts of the glass do not. This uneven stress can cause the crack to grow rapidly and unpredictably.
Stuart Pyburn explains that an expanding crack is “like a mini earthquake. The pieces move and shift,” which can result in complete shattering with very little pressure. A catastrophic failure can even create glass shards that pose a risk of personal injury.
Stuart cautions that, in the event of a crack or shatter, you should immediately unplug the appliance and call an appliance expert to fix the range.
Unsafe and inefficient cooking
A cracked glass stove fundamentally alters the way your appliance is meant to operate. The crack creates a weak point where heat can escape, disrupting the even, consistent heat transfer from the element to your cookware.
Uneven heat distribution makes cooking difficult and unpredictable. You might find that your food burns in one area while remaining undercooked in another. This not only ruins your meal but can also be a safety concern.
Hot and cold spots on the stovetop can cause oil to splatter erratically or food to stick and burn onto the cooking surface, increasing the chances of a kitchen fire. A stovetop that can no longer cook evenly is not only a frustrating tool, but a hazardous one.
Bacterial growth
A less obvious, but still significant, danger of a cracked glass stove is the hygiene risk. The smooth, non-porous surface of a glass cooktop is designed to be easy to clean, preventing the buildup of food particles and bacteria. A crack, however, creates a perfect crevice for germs to thrive.
Food spills, grease, and moisture can easily get trapped in the crack. Cleaning these areas is nearly impossible without causing further damage, allowing the trapped organic matter to become a breeding ground for bacteria.
The Financial Pitfall of Procrastination
Many people put off dealing with a cracked glass stove because they fear the cost of a repair, but procrastination almost always leads to a much more expensive solution. A glass replacement is an affordable way to fix a glass stovetop. Continuing to use the appliance, however, can lead to complete and total failure of the range.
Furthermore, using a damaged appliance will likely void any remaining manufacturer's warranty. If you were to experience a serious malfunction or a fire due to the crack, the manufacturer may refuse to cover the cost, leaving you to foot the bill for both a new stove and any potential property damage.
Contact Mr. Appliance for Glass Stovetop Repair
While it may seem harmless, that small crack in your glass stovetop is a ticking time bomb. A stovetop crack isn’t just a cosmetic issue: It's a serious electrical, fire, and safety hazard that can escalate rapidly.
The risk of electrical shock, fire, and catastrophic shattering far outweighs the convenience of putting off a repair. For the safety of your home and family, immediately unplug the appliance and stop using it the moment you notice a crack. Do not attempt a DIY fix, as they can be just as dangerous as continuing to use your broken appliance.
