Common Gas Cooktop Problems We Can Help With
Our network of skilled engineers has seen it all. They have the experience to quickly diagnose and rectify a wide range of issues across all major brands, from Bosch and Neff to Smeg and Rangemaster. Here are some of the most frequent faults they are called out to fix.
Burner Fails to Light
One of the most common complaints is a burner that refuses to light, either with the built-in igniter or with a match. You might hear the 'clicking' of the spark, but no flame appears. This can be caused by several issues, such as a blocked burner jet preventing gas from flowing, a faulty spark igniter, or moisture around the burner assembly after cleaning. A Gas Safe engineer can safely clear any blockages and test or replace the ignition components to restore function.
Weak or Inconsistent Flame
Is your flame yellow instead of a crisp blue? Or perhaps it’s weak and uneven, making it difficult to cook effectively. A healthy gas flame should be steady and blue with a slightly lighter blue core. A yellow or orange flame often indicates a problem with the gas-to-air ratio, which could be due to partially blocked burner ports. A weak flame might point to a problem with the gas pressure regulator. An expert can clean the burner assembly thoroughly and test the gas pressure to ensure your cooktop performs as it should.
The Smell of Gas
If you can smell gas when the cooktop is not in use, this requires immediate action. Do not operate any electrical switches or create any sparks. You should turn off the gas at the emergency control valve (usually located by your meter), open all windows and doors to ventilate the property, and then call the National Gas Emergency Service. Once the immediate danger has been neutralised, you will need a Gas Safe engineer to trace and repair the leak. The source could be a degraded flexible hose or a failed seal within the appliance itself. This is a critical gas repair that must not be delayed.
Constant Clicking from the Igniter
A relentless clicking sound from the spark igniter, even after the burner is lit or turned off, is another frequent issue. This is usually down to a fault in the ignition system. It could be caused by a misaligned burner cap, trapped moisture interfering with the circuit, or a failing spark module that needs replacing. While not as immediately dangerous as a gas leak, it’s an annoyance that indicates a component is failing and should be addressed by a professional.
Professional Gas Cooktop Installation Services
Beyond repairs, the correct installation of a new gas cooktop is fundamental to its safety and performance. Whether you’re upgrading your kitchen, replacing an old appliance, or installing a hob for the first time, this is a task that must be carried out by a Gas Safe registered engineer.
A professional gas cooktop installation involves more than just connecting a pipe. The engineer will:
- Safely disconnect and remove your old appliance.
- Ensure the new cooktop is a suitable fit for your worktop and that there is adequate ventilation.
- Use the correct, legally compliant fittings and hoses to connect the appliance to the gas supply.
- Perform a thorough gas tightness test to check for any leaks in the system.
- Test all burners and controls to ensure they are operating at the correct pressure and combusting safely (a process known as commissioning).
- Provide you with a Gas Safety Certificate for the installation, which is a vital document for your home records.
This process applies to both natural gas cooktops and those designed for LPG (Liquefied Petroleum Gas), which are common in rural homes not connected to the mains gas network. If you require LPG gas cooker repairs or installation, it is vital to ensure the engineer is specifically qualified for LPG work, which will be stated on their Gas Safe ID card.
