If you’ve ever seen a line or a spider‑web pattern on your hob glass, you know how annoying it looks. A cracked hob can stop the burners from heating properly and it makes cooking feel risky. The good news? Most cracks are fixable without calling a pro, as long as you know what you’re dealing with.
Heat is the main culprit. When a pan sits too long on a high setting, the glass expands quickly and can split. Sudden temperature changes – like pouring cold water on a hot surface – do the same thing. Heavy pots, especially if you drop them, add stress points that turn into cracks over time. Even a small chip can grow if you keep using the hob.
Look for any hairline lines, dark spots, or a fuzzier area on the glass. Shine a flashlight across the surface; a crack will reflect light differently than the rest of the glass. If the burners flicker or the heat feels uneven, that’s another sign. Catching a crack early means you can often repair it yourself instead of needing a full replacement.
Before you start any repair, turn the hob off at the mains and let it cool completely. Safety first – no electricity should be flowing while you work.
Most DIY fixes involve a glass repair kit designed for cookware surfaces. These kits include a clear epoxy resin that you spread over the crack, let it cure, then sand smooth. Follow the kit’s instructions closely: usually you’ll apply the resin, wait 15‑30 minutes, then wipe away excess before it hardens.
If the crack is bigger than a finger‑width or goes right to the edge, a DIY fix may not hold up. In those cases, replace the glass panel. You can order the correct size from the manufacturer or a local supplier. Removing the old glass usually means unscrewing the hob’s front frame, lifting the panel, and sliding out the broken piece.
When you have a new panel, place it gently, align the mounting holes, and tighten the screws evenly. Don’t over‑tighten; the glass can stress again. Re‑connect the power and test each burner to make sure the heat spreads evenly.
Even after a successful repair, keep an eye on the hob. Avoid using metal cookware that can scratch the surface, and never heat an empty pan on high. A little habit change can add years to your hob’s life.
If you’re unsure about any step, or the crack seems to affect the heating element underneath, call a local repair service. They can assess whether a simple glass swap will do or if a deeper issue needs fixing.
In short, most hob cracks are caused by heat stress or impacts, they’re easy to spot, and you can often repair them with a resin kit or a new glass panel. With the right tools and a careful approach, you’ll have a smooth, safe hob back in action without breaking the bank.
