Gas appliance servicing is a scheduled check and clean of a gas appliance to keep it burning safely and efficiently. Gas appliance repair is fixing a fault, such as an igniter that will not spark, a burner that will not stay lit, or a heater that smells or soots. Both are gas work in Queensland, so a licensed gasfitter should do anything beyond basic cleaning set out in the owner's manual. In Mackay this mostly means cooktops, ovens, outdoor barbecues, patio heaters and the occasional indoor heater used on cooler winter nights.
Why this page covers more than heaters
In southern cities, gas heater servicing is a big seasonal job. Mackay's tropical climate means far fewer homes rely on gas space heating. Cooking appliances, outdoor entertaining equipment and water heaters are much more common, so this page covers servicing and repair for all of them. Gas water heaters have their own page: see gas hot water.
Signs an appliance needs attention
Queensland gas safety guidance highlights several warning signs:
- the igniter clicks many times without lighting;
- the flame is uneven, sputters, or burns yellow instead of a steady blue;
- soot, scorch marks or discolouration appear around the appliance;
- there is a gas smell when the appliance is on or off;
- the appliance is rusty, corroded or physically damaged;
- a portable outdoor heater has not been checked for a long time.
Headaches, dizziness or nausea in a room with a gas appliance running can point to carbon monoxide. Turn the appliance off, get fresh air, and seek medical help if symptoms continue.
What a service generally includes
Service scope varies by appliance and provider. Across benchmark competitor pages, typical tasks include:
- Visual inspection. Checking the appliance, its connection, hoses and surroundings for damage, corrosion and combustible materials nearby.
- Cleaning. Clearing burner ports, pilot assemblies, filters and air inlets so the gas burns properly.
- Ignition and safety devices. Testing igniters, thermocouples and flame failure devices so gas cuts off if the flame goes out.
- Pressure and combustion checks. Measuring the gas pressure and checking the flame, and testing for carbon monoxide where the appliance type calls for it.
- Leak test. Checking the connection and nearby fittings for escaping gas.
- Report. Explaining what was found and recommending repairs or replacement where needed.
Common repairs
| Problem | Possible causes a gasfitter may check |
|---|---|
| Burner will not stay lit | Faulty thermocouple or flame failure device, dirty burner, low gas supply |
| No spark | Worn igniter, wiring or electrode problem, moisture after wet weather |
| Yellow or lazy flame | Blocked air inlet, wrong injector for the gas type, dirty burner |
| Barbecue flare-ups or uneven heat | Blocked burners, damaged hose or regulator, grease build-up |
| Gas smell at the appliance | Loose fitting, perished hose, internal valve fault |
Repairs may involve replacing components, converting injectors, or advising that an appliance is not economical or safe to repair.
Outdoor appliances in a tropical climate
Mackay's humidity, salt air near the coast and heavy wet-season rain are hard on outdoor gas gear:
- Barbecues. Hoses and regulators break down from UV and heat, and spider webs and insects can block venturi tubes. Inspect them before the entertaining season.
- Patio heaters. These must only be used outdoors with plenty of fresh air. Queensland advises having outdoor heaters serviced regularly, ideally before winter.
- Outdoor kitchens. Covered areas still need enough ventilation, and fixed appliances should be checked after major storms.
Indoor heaters
Some Mackay homes keep a gas heater for the occasional cool night, often connected through a bayonet. Heaters that have sat unused for long stretches can collect dust and insects. Have them checked before you use them again. Never use outdoor heaters inside.
How often to book a service
There is no single interval that suits every appliance. Follow the manufacturer's instructions first. Queensland guidance says gas appliances should be checked and serviced periodically by a licensed gasfitter. For outdoor heaters it suggests yearly servicing before winter. If an appliance shows any warning sign, do not wait for the scheduled service.
Repair or replace?
When deciding, consider:
- the age of the appliance and whether parts are still available;
- whether it has modern safety features such as flame failure devices;
- the cost of repair compared with a new appliance;
- whether the appliance matches your gas type.
If you decide to replace it, see gas appliance installation.
Preparing for a visit
- Have the make and model ready, or a photo of the rating plate.
- Describe the symptoms and when they happen.
- Clear access to the appliance and the gas connection.
- Mention whether you use LPG cylinders, a bulk tank or a meter.
Frequently asked questions
How often should I service a gas cooktop or barbecue?
Follow the manufacturer's recommendation. Book sooner if the igniter struggles, the flame looks wrong, or you smell gas. Outdoor equipment in coastal Mackay may need checking more often because of corrosion.
Why does my gas cooktop burner keep going out?
A common cause is a dirty or faulty flame failure device or thermocouple, which shuts off the gas when it does not sense a flame. Dirty burner ports and low supply pressure can also be to blame. A gasfitter can test the parts.
Can a gas appliance give off carbon monoxide?
Yes. An appliance that burns gas incompletely can produce carbon monoxide, especially with poor ventilation. Using outdoor heaters indoors is a known risk. Regular servicing and correct use reduce it.
Is it worth repairing an old gas heater?
It depends on its condition, parts availability and safety features. Many people in Mackay use heaters only occasionally, so a safety check before use is often more important than an upgrade.
Can I replace my barbecue hose and regulator myself?
Portable barbecues that run on their own cylinder use the regulator supplied with the appliance, and the manufacturer's instructions apply. Fixed barbecues connected to the house gas supply are part of the gas installation, so changes need a licensed gasfitter.
