Glass Hob Repair: Simple Solutions & Pro Help

If your glass hob is cracked, flickering, or just not heating right, you don’t have to panic. Most issues are caused by everyday kitchen mishaps and can be sorted quickly with the right approach. Below, we break down the most common problems, easy DIY checks, and when it’s smart to call a professional.

Common Glass Hob Problems

Cracks are the most visible sign of damage. Even a hairline crack can spread if you keep using the hob, so it’s worth inspecting the surface after any heavy pot or accidental impact. Dark spots or uneven heating often mean a faulty heating element or a loose connection under the glass.

Another frequent complaint is a buzzing or sizzling noise that doesn’t stop when you turn the hob off. That usually points to a stuck control board or a sensor that’s gone bad. Finally, if the touch controls are unresponsive, moisture may have seeped into the panel, especially after a splash.

DIY Fixes You Can Try Safely

Start with a power reset. Turn off the circuit breaker for a minute, then switch it back on. Many electronic glitches clear up with a fresh start. If the hob still misbehaves, clean the glass surface with a non‑abrasive cleaner and a soft cloth – residue can cause false readings.

For cracked glass, you can apply a clear, heat‑resistant epoxy designed for stovetops. Follow the product instructions, spread a thin layer over the crack, and let it cure fully before using the hob again. This is a short‑term fix; plan to replace the glass panel eventually.

If the heating zones are uneven, check the knobs or touch controls for debris. A simple blow‑out with compressed air can remove dust that interferes with the sensors. When you feel comfortable, you can unscrew the hob (make sure it’s unplugged) and inspect the wiring for loose connections. Tighten any loose screws, but don’t force anything.

When you’ve tried these steps and the hob still won’t work, it’s time to call a professional. A qualified technician can test the internal components with specialised tools, replace damaged heating elements, or fit a new glass panel. Trying to replace the glass yourself without the right tools can lead to injury or more damage.

Regular maintenance helps avoid costly repairs. Wipe spills immediately, use only cookware with a flat base, and avoid sliding heavy pots across the surface. A quick visual check each month can spot early cracks or wear before they become big problems.

In short, many glass hob issues can be diagnosed and fixed at home with a few simple steps. If you’re unsure or the problem involves internal electronics, trust a professional to keep your kitchen safe and your hob looking like new.
