If only one LPG appliance has stopped working while everything else is operating as normal, the issue is unlikely to be related to your gas supply. Common causes include ignition faults, electrical issues, blocked burners, safety systems activating or general wear and tear. If multiple appliances have stopped working, the issue is more likely to be related to the LPG supply.
If you've gone to turn on your LPG hob, switch on your boiler, light your gas fire, or start up a piece of gas-powered equipment only to find it’s not working, it’s natural to wonder whether you’ve run out of gas. For many LPG users, a gas appliance failing to ignite is often the first sign that something isn’t right.
The same applies in commercial settings. Whether you’re running a hospitality business that relies on LPG for cooking and heating, a manufacturing facility using LPG-powered processes, or another off-grid operation that depends on a reliable gas supply, an appliance failure can quickly become a concern.
However, before checking your LPG tank level or assuming there’s a problem with your gas supply, it’s worth taking a moment to look at your other appliances and equipment. If they’re operating normally, the issue is likely to be isolated to the appliance itself rather than the LPG supply.
Understanding the difference between an appliance-specific fault and a wider LPG supply issue can help you identify the likely cause more quickly, avoid unnecessary callouts, and ensure you contact the right person for support. In this blog, we’ll explain what to look for when it’s unlikely to be a supply issue, and when it’s time to call a Gas Safe registered engineer.
The first question – is it just one appliance?
One of the quickest ways to determine whether you’re dealing with an appliance fault or an LPG supply issue is to check your other gas appliances.
In a home, you might find that your LPG hob won’t light but your boiler is working normally, your LPG boiler isn’t firing up but your cooker and gas fire are operating as expected, or your gas fire won’t stay lit, whilst the rest of your LPG appliances continue to work without issue.
For commercial gas users, the same principle applies. For example, a commercial kitchen range may stop working while other catering equipment remains operational, a single heating appliance may fail while the rest of the building continues to receive heat, or one piece of manufacturing equipment may be affected, while other LPG-powered processes continue as normal.
If this sounds familiar, the good news is that your LPG tank and supply are probably not the problem.
When gas is reaching your property correctly, but only a single appliance or item of equipment is affected, the cause is usually specific to that appliance. Common issues include ignition faults, worn components, electrical problems, blocked burners, safety devices activating, control system faults, or a defect requiring attention from a Gas Safe registered engineer.
In most cases, if only one LPG cooker, hob, boiler, gas fire, commercial catering appliance or industrial gas-powered system is affected, there’s no need to panic about your gas supply. The fact that other appliances are working normally is a strong indication that LPG is still flowing from the tank and through your property’s pipework.
If all LPG appliances have stopped working
The situation is very different if none of your LPG appliances are working.
You might notice that your hob, cooker, boiler and gas fire all fail to ignite, no appliances appear to be receiving LPG, your heating and hot water have stopped working at the same time, or you suspect that your LPG tank may be running low or empty.
For businesses, this could mean multiple catering appliances shutting down, site heating systems failing simultaneously, or several LPG-powered processes stopping at the same time.
When multiple appliances stop working simultaneously, it’s much more likely that the issue lies with the LPG supply rather than an individual appliance. Potential causes could include a low or empty LPG tank, a valve that has been closed accidentally, a problem affecting the gas supply to the property or an interruption following maintenance or other work on the LPG system.
If every LPG appliance in your home or business has stopped working, we recommend checking your tank gauge first and carrying out a few basic supply checks before arranging an appliance inspection. Unlike a fault affecting a single appliance, a whole-property loss of gas points towards a wider supply issue that may require assistance from your LPG supplier.
As a general rule, one appliance not working usually suggests an appliance fault, while all appliances failing to work is often a sign of an LPG supply problem. Understanding this distinction can help you get the right support more quickly, reduce downtime, and minimise disruption to your home, hospitality business, manufacturing operation or other off-grid enterprise.
Why is my LPG appliance not working?
If you’ve established that only one LPG appliance is affected and everything else is working normally, there are several common causes worth considering.
- Ignition problems: Many modern appliances rely on electronic ignition to create the spark needed to light the gas. If that system develops a fault, the appliance may fail to ignite even though LPG is still being supplied to the property. Some signs of an ignition-related problem include no clicking sound when attempting to ignite, a weak or absent spark, flat batteries in battery-powered ignition systems or an electrical supply issue affecting the appliance.
- Boiler faults: LPG boilers contain a range of sensors and safety features designed to protect both the appliance and the heating system. As a result, a boiler can sometimes shut itself down even when there is no issue with the gas supply. Common boiler-related faults include low system pressure, error or fault codes displayed on the control panel, frozen condensate pipes during colder weather, faulty sensors or components, or circulation or pump issues within the heating system.
- Built-in safety features: Many LPG appliances are designed to automatically shut down if they detect a potential fault or unsafe operating condition. Depending on the type of appliance, this could include flame supervision devices shutting off the gas supply, overheat protection systems activating, safety interlocks preventing ignition or sensors detecting operating faults.
- Wear, tear or maintenance issues: Like any piece of equipment, LPG appliances require regular maintenance to continue operating efficiently. Over time, components such as burners, jets and pilot assemblies can become affected by dust, debris, grease or general wear and tear. This can lead to difficulty lighting the appliance, uneven or poor-quality flames, reduced performance, or the appliance repeatedly cutting out.
Troubleshooting common LPG appliance problems
Before assuming there’s a problem with your LPG supply, it’s worth carrying out a few simple checks.
LPG hob or cooker not lighting
- Check whether other gas appliances are working
- Listen for the ignition clicking
- Ensure the appliance has an electrical supply where required
- Check burners for food debris, grease or blockages
LPG boiler not firing up
- Check for fault or error codes
- Check the system pressure is within the recommended range
- Confirm the electrical supply is switched on
- Check whether other LPG appliances in the property are working
Gas fire won’t ignite
- Check batteries in any remote controls or ignition systems
- Ensure controls are set correctly
- Look for signs of wear around the pilot light assembly
- Confirm your other LPG appliances are operating normally
Commercial LPG equipment not working
For hospitality, leisure, manufacturing businesses and any other sectors that rely on LPG, the same principle applies. If one commercial catering appliance, heating system or LPG-powered process has stopped working while everything else remains operational, the issue is usually isolated to that piece of equipment.
When it is unlikely to be the LPG supply
Your LPG supply is probably not the cause if:
✅ Other LPG appliances are working normally
✅ The LPG tank gauge shows there is sufficient gas in your tank
✅ Only one appliance is affected
✅ The appliance displays a fault code or warning light
✅ The issue appears related to ignition or electrical operation
When to contact a Gas Safe engineer
You should contact a Gas Safe registered engineer if:
- An appliance repeatedly fails to ignite
- The appliance is displaying fault codes you can’t resolve
- You suspect an internal appliance fault
- The appliance has not been serviced for some time
- The appliance keeps cutting out or is not operating correctly
- You notice unusual smells, operating noises or changes in performance
- You notice unusual flame patterns, such as yellow, orange or lazy flames instead of a crisp blue flame
It is important not to ignore changes in the appearance of a gas flame. Unusual flame patterns can indicate that the appliance is not burning fuel correctly and, in some cases, may increase the risk of carbon monoxide (CO) being produced. Other warning signs can include excessive condensation, staining or sooting around the appliance.
If you suspect a carbon monoxide risk, switch off the appliance, ensure the area is well ventilated, and seek professional advice immediately. A Gas Safe registered engineer will be able to safely diagnose the fault and ensure the appliance is operating correctly, safely and efficiently.
This not only helps keep your home or business safe but can also prevent a minor appliance fault from developing into a more costly repair.
FAQs:
Can I have gas if my boiler isn’t working?
Yes. If your LPG hob, cooker or gas fire are still working, gas is still reaching your property. The issue is more likely to be with the boiler itself.
Why won’t my LPG hob light?
Common causes include ignition faults, blocked burners, electrical issues or worn components.
How do I know if my LPG tank is empty?
Check the contents gauge on your LPG storage tank. If multiple appliances have stopped working and the gauge is showing low levels, you may need a delivery.
Should I call my LPG supplier or an engineer?
If only one appliance is affected, contact a Gas Safe registered engineer. If multiple appliances have stopped working or you suspect a supply issue, contact your LPG supplier.
