If you notice a crack in your electric hob, don’t panic. A cracked surface can look scary, but with the right steps you can keep your kitchen safe and get the hob working again.
First, turn off the power at the fuse box. A live hob with a cracked glass can expose the heating element and create a shock hazard. Look closely at the crack – is it a tiny hairline line or a big break that runs across the whole panel? Small chips often mean you can replace just the glass top. Big cracks may mean the whole hob needs a new surface or even a new unit.
Check for any signs of moisture under the glass. If water has seeped in, it could cause short‑circuits. Also, run a quick visual test of the burners. If a burner doesn’t heat up, the crack might have damaged the element.
When the crack is minor, you can replace the glass yourself. You’ll need a replacement hob glass that matches your model, a screwdriver set, and a pair of safety gloves. Follow these steps:
If the crack is larger than the glass panel, you’ll need to replace the whole hob surface. That usually involves disconnecting the wiring, removing the old unit, and fitting a new one. Unless you’re comfortable with electrical work, it’s safer to let a qualified electrician handle this part.
Even after a successful DIY repair, keep an eye on the hob for the first few days. Any strange smells, flickering lights, or uneven heating mean you should stop using it and call a professional.
When to call a pro? If the crack is deeper than the glass, if you see exposed wiring, or if the hob still won’t heat properly after a glass swap. A certified appliance repair technician can diagnose hidden faults and ensure the job meets safety standards.
Lastly, keep your hob clean and avoid heavy pots that can stress the glass. A soft silicone mat can protect the surface while cooking.
Cracks happen, but with these steps you can decide whether a quick DIY fix will do or if it’s time for an expert. Stay safe, keep the power off until you’re sure, and enjoy a working hob again soon.
