Short answer: If your gas oven is under six years old and the fix costs less than half the price of a comparable new model, repair usually wins. If it’s older, needs repeated fixes, has safety issues, or the quote creeps past that 50% mark, replacement is typically the smarter spend. CHOICE notes large kitchen appliances such as ovens are generally worth repairing for at least the first six years and parts for 10-year-old units can be hard to source.

The deeper dive – costs, age and safety
1) What repairs actually cost
Common gas-oven fixes in our region fall into a few buckets:
- Igniter failure – often the culprit when the oven clicks but won’t light. Typical repair $150–$300 including parts and labour.
- Thermostat or temperature sensor – inconsistent heat or burnt edges. Often $200–$400, model-dependent. (Typical local ranges – our technicians confirm on site.)
- Door seal, hinges, fans – heat escaping or uneven bakes. Usually $120–$300, depending on parts and access.
On Heat and Cool’s jobs across Greater Geelong, most appliance repairs land between $200 and $600, with replacements usually $1000+ before installation.
2) What replacement really costs
CHOICE’s recent wall-oven tests show a wide spread: you’ll see units from ~$469 up to ~$9499, with many good performers under $3000. Installation adds ~$90–$600 depending on wiring, gas connection and cabinetry, plus gasfitter time where needed. Gasfitters typically charge $100–$200 per hour in Australia; complex gas line work can add extra.
3) Age and part availability
If your oven is under six years old, repair is often sensible; around ten years, parts availability becomes the swing factor; well beyond ten, multiple faults plus scarce parts can tip the maths toward replacement. CHOICE calls out the ten-year mark as a practical point where parts may be harder to find.
4) Safety trumps everything
Any sign of incomplete combustion, soot, yellow flames, or persistent headaches after cooking is a red flag. Energy Safe Victoria reminds households that gas appliances can spill carbon monoxide without smell or colour, and that servicing must be done by a licensed gasfitter with proper ventilation provisions.
In short: if a technician flags a safety defect, don’t delay – fix it or replace the oven.
A simple rule you can use at home
Use the 50% rule plus age and safety:
- Repair if: the quote is ≤50% of a similar new oven, the unit is under ~6 years, and no safety issues are present.
- Replace if: the quote is >50% of new, parts are discontinued, you’ve had two or more similar failures in a year, or a tech identifies a safety risk.
Typical scenarios – what usually makes sense
Scenario Age Likely repair cost Typical new + install Our take
Won’t light – igniter faulty 3–7 yrs $150–$300 $1200–$3000+ Repair is often the best value.
Temps drifting – bad sensor/thermostat 5–9 yrs $200–$400 $1200–$3000+ Repair first, check parts availability.
Door won’t seal – heat loss Any $120–$300 $1200–$3000+ Repair seals/hinges unless other faults stack up.
Multiple faults, parts NLA 10–15 yrs $400–$800+ $1500–$4000+ Replace – cost and downtime add up.
Safety defect – CO risk or gas leak Any Varies Varies Make safe immediately – repair to a compliant standard or replace.
Prices are indicative for Greater Geelong and surrounds. Your kitchen layout, cabinetry, and brand can shift the totals.
What readers ask us most
Is repairing a gas oven actually cheaper?
Often, yes. Heat and Cool’s repair jobs commonly sit in the $200–$600 window, well below most replacement totals. The exception is older units with repeated failures or scarce parts.
How long do gas ovens last?
Consumer guidance in Australia puts ovens roughly in the 10–15-year range, with premium models lasting longer if maintained. After around 10 years, plan for parts to be trickier to source.
What about running costs – gas vs induction?
This article focuses on the repair-vs-replace decision for gas ovens. For cooktops, Victorian programs highlight efficiency and health benefits of induction and note strong bill savings potential – but the choice depends on your tariffs, cookware and layout. If you’re already replacing multiple gas appliances, it can be a good time to ask our team about future-proofing the kitchen.
Is gas work DIY-able?
No. In Victoria, only licensed gasfitters can legally install, service or modify gas appliances and pipework. It’s a safety and compliance issue – and your insurance may depend on it.
What if I can’t be without an oven for long?
Tell us when you book. For many faults, we carry common parts – igniters, seals, thermostats – to aim for a same-day fix when practical. If the oven is beyond repair, we can quote a like-for-like replacement and coordinate installation.
How Heat and Cool makes the choice easier
- Up-front diagnosis – a licensed tech inspects ignition, combustion, regulators and seals, then gives you a clear repair price and a comparable replacement option.
- Transparent numbers – we benchmark against current retail pricing and installation costs, so you can see the gap.
- Safety and compliance – repairs and installs are completed by qualified gasfitters, with CO-safety checks and documentation.
- Local and fast – servicing Geelong, the Surf Coast, The Bellarine, Werribee, and surrounds, with same-day repair where parts allow.
