Gas Hob Repair When Your Burner Will Not Light

A burner that clicks but will not light can turn an ordinary evening meal into a real nuisance. More seriously, a flame that goes out unexpectedly, burns yellow or smells of gas needs prompt attention. Professional gas hob repair is about restoring your cooker safely, not simply getting a burner working for the moment.

For households and landlords, the right response depends on the fault. A little moisture around a burner can sometimes be resolved with careful cleaning and drying. Anything involving a gas smell, an unreliable flame or a burner that will not stay lit should be left to a Gas Safe registered engineer.

When to stop using your gas hob

If you can smell gas, turn off the hob if it is safe to do so, open doors and windows, avoid switches and naked flames, and leave the property. Call the Gas Emergency Service on 0800 111 999 from a safe location. Do not try to identify the source yourself or relight the appliance.

You should also stop using the hob and arrange an inspection if a burner produces a persistently yellow, orange or uneven flame. A healthy gas flame is generally steady and predominantly blue. Flame colour can be affected by a dirty burner cap, but it can also point to incomplete combustion or an issue with the gas supply to that burner. It is not a fault to ignore.

A burner that lights and then goes out as soon as you release the control is another reason to book a repair. Modern hobs use a flame supervision device to shut off the gas if the flame fails. That safety feature is there for good reason, and it should never be bypassed.

Common gas hob faults and what they can mean

A hob can fail in several ways, and the symptoms often give an engineer a useful starting point. Diagnosis still matters because two similar-looking faults may have different causes.

The burner will not ignite

If there is no clicking sound when you turn the control, the ignition system may not be operating correctly. If it clicks repeatedly but no flame appears, the burner may be blocked, wet, incorrectly seated or not receiving gas as it should. Food spills, grease and cleaning residue can interfere with the small openings that distribute gas around the burner.

Before arranging a call-out, make sure the burner cap and crown are cool, clean, dry and fitted in the correct position. Use a soft cloth and avoid forcing anything into the burner openings. If the problem remains, do not take the hob apart. An engineer can assess the ignition components, burner assembly and gas operation safely.

One burner is weak or flames unevenly

A low, patchy flame on one ring is commonly linked to blocked burner ports or a cap that is not sitting flat. It may be possible to remove surface debris once the hob is fully cool. However, if the flame continues to lift away from the burner, sputters, burns yellow or changes significantly after cleaning, stop using that burner.

The trade-off is simple: basic surface cleaning can be sensible maintenance, while deeper investigation involves gas-carrying parts and should be handled by a qualified professional. Replacing a burner cap without confirming the underlying fault can also waste money if the issue lies elsewhere.

The hob keeps clicking after use or after a spill

Continuous clicking is often caused by moisture around the ignition electrodes following a boil-over or thorough clean. Letting the hob dry naturally may resolve it, provided there is no gas smell and the burners are off. Do not use a hairdryer or apply heat directly to the appliance.

If clicking carries on after the hob has dried, or happens without any recent spill, an engineer should inspect it. Persistent ignition faults can be disruptive, particularly when the clicking starts at night or prevents normal use of the appliance.

The burner will not stay alight

Where a flame dies when the knob is released, the flame supervision device may not be sensing the flame correctly. A dirty burner, misaligned cap or faulty component can cause this. Holding the control in for a few seconds as instructed by the manufacturer is normal, but repeatedly holding it in for much longer is not a reliable workaround.

Do not wedge, tape or modify a control to keep gas flowing. A proper repair protects the safety function designed to prevent unburned gas entering the room.

What to do before booking gas hob repair

A few clear details can help make a repair visit more efficient. Note whether the problem affects one burner or all of them, whether you hear clicking, and whether the flame is blue, weak or unstable. If safe, take a photograph of the burner arrangement and have the appliance make and model available.

It is also useful to explain when the fault began. Did it follow a spill, cleaning, a power cut or gradual loss of performance? For a landlord or managing agent, include whether the property is occupied and whether the tenant has reported any smell of gas. These details help establish the urgency and ensure the correct approach on arrival.

Avoid trying internet fixes that involve removing panels, adjusting gas controls or altering parts beneath the hob. A gas appliance can appear straightforward from above, but safe diagnosis requires checks that go beyond whether a flame is visible.

What a professional repair visit should involve

A competent gas hob repair begins with the reported symptoms and a visual condition check. The engineer will assess the burners, caps, ignition and flame behaviour, then investigate the relevant components in line with safe working procedures. The aim is to identify the actual cause rather than fitting parts based on guesswork.

Depending on the fault, the repair may involve cleaning or replacing a burner component, correcting an ignition issue, replacing a failed safety-related part or addressing a control fault. Parts availability can affect whether the repair is completed during the first visit. Older or discontinued models may require a cost comparison between repair and replacement, particularly if several parts are worn.

A good engineer will explain the fault in plain language, outline the proposed work and provide a clear quotation before proceeding where further parts or labour are needed. Once work is complete, the hob should be tested for correct ignition, stable flames and safe operation.

Repair or replacement: which is the sensible option?

Many gas hob faults are repairable, especially when the appliance is otherwise in good condition and the required part is available. A single faulty igniter, burner cap or flame-sensing component does not automatically justify replacing the whole hob.

Replacement may make more sense when the appliance is old, parts are no longer available, corrosion has affected several areas or the cost of multiple repairs approaches the cost of a suitable new unit. For a rental property, reliability and access to future parts are often as important as the immediate price. For an owner-occupier, the decision may also depend on how well the hob has performed and whether other burners are showing signs of wear.

An engineer can give an honest view once the fault has been diagnosed. That is more useful than choosing a replacement before knowing whether a straightforward repair is possible.

Keeping your hob working safely between visits

Regular care helps prevent avoidable burner problems. Wipe spills once the hob is cool, keep burner caps correctly positioned and dry components thoroughly after cleaning. Use products recommended for the surface material, and avoid soaking or aggressively scraping ignition areas.

If a burner starts to behave differently, deal with it early rather than waiting for a complete failure. Small changes such as delayed ignition or an uneven flame are easier to investigate before they interrupt cooking or create a safety concern.
