If your gas hob sputters, won’t ignite, or smells funny, you’re probably wondering what to do first. The good news is many issues are quick fixes you can do yourself with a few tools and a bit of caution. In this guide we’ll walk through the most common reasons a gas hob stops working, show you safe DIY fixes, and tell you when it’s wise to call an expert.
Most gas hobs fail for three main reasons: blocked burners, faulty igniters, or a supply problem. A burner can get clogged with food debris or grease, which blocks the gas flow and stops the flame. Igniters—those little clicking pieces that spark the flame—can wear out or get covered in grime, so they won’t spark at all. Finally, if the gas supply valve is partially closed or the pipe has a leak, none of the burners will fire.
Other occasional culprits are loose connections and broken safety valves. A loose connection can happen after a heavy pot is moved around, and a broken safety valve may stop the gas from reaching the hob entirely. Spotting the exact cause saves you time and prevents unnecessary repairs.
Before you reach for a professional, try these easy steps. First, turn off the gas supply at the main valve and let the hob cool completely. Remove the burner caps and clean them with warm soapy water. Use a toothbrush to scrub out any clogged holes—make sure they are clear before re‑assembling.
Next, check the igniter. Wipe it gently with a dry cloth to remove any oil or food residue. If it still won’t spark, you can test it with a multimeter (set to ohms). A healthy igniter usually reads between 500 and 1,000 ohms. Anything far outside that range means the part needs replacing.
Finally, verify the gas supply. Open the main valve a little and listen for a hissing sound; if you smell gas, shut it down immediately and call a qualified engineer. If everything looks normal, try lighting the burners again. Often a quick clean and a fresh spark are all you need.
If after these steps the hob still won’t work, it’s time to call a professional. Gas work can be dangerous if you’re not trained, and a certified engineer will safely check the gas line, replace faulty components, and ensure your stove meets safety standards.
Keeping your gas hob in good shape also means regular maintenance. Wipe down spills right away, avoid using abrasive cleaners on the igniters, and schedule a yearly check‑up if you use the stove heavily. A little care now can prevent costly breakdowns later.
