Gas Hob Troubleshooting – Quick Fixes You Can Do Today

Got a gas hob that won’t light or is giving you a wobbly flame? You’re not alone. Most homeowners run into a few typical hiccups, and many of them can be sorted without calling a tech. Below we walk through the most common problems, easy DIY steps, and the signs that you should hand the job over to a professional.

Common Gas Hob Problems and Simple Fixes

1. No spark, no flame. First, check the safety cap on the burner. If it’s out of place or dirty, the sensor won’t see a flame and won’t spark. Clean any food debris, then reseat the cap. Next, make sure the gas supply valve is fully open. A partially closed valve can starve the burner of fuel, preventing ignition.

2. Weak or uneven flame. This usually means the burner holes are clogged. Remove the burner grate, lift the burner, and soak it in warm, soapy water for a few minutes. Use a soft brush or a pin to clear each hole. Rinse, dry, and reinstall – the flame should become steady and blue.

3. Smell of gas. If you detect a faint gas odor, turn the knob to the “off” position, open a window, and let the kitchen air out. Check the connections for loose fittings. Do not try to light the hob again until the smell disappears; a lingering leak needs a qualified technician.

4. Igniter clicks but no flame. The igniter can wear out after years of use. Give it a quick clean with a dry cloth – sometimes carbon buildup stops the spark. If cleaning doesn’t help, the igniter may need replacement, which is a job for an experienced repairer.

5. Burner won’t stay on. Some hobs have a safety feature that cuts off gas if the flame goes out. If the flame keeps dying, the thermocouple (the safety device) might be dirty or faulty. Light the burner, then gently clean the tip of the thermocouple with a fine steel wool. If the problem persists, it’s best to let a pro handle the part.

When It’s Time to Call a Professional

If you’ve tried the steps above and the hob still misbehaves, or if you’re uncomfortable working with gas, call a qualified repair service. A certified technician can safely test gas pressures, replace igniters, and check the internal wiring. Trying to fix a gas leak yourself is risky and could void any warranty.

Another scenario for calling a pro is when the hob shows error codes on a digital display. Those codes usually point to internal sensor issues that need specialized tools to diagnose.
