Quick Answer
Use the 50% rule: if oven repair exceeds 50% of a new model’s cost, replace it.
Most oven failures are safely repairable on machines under 12 years old.
Gas and electric repairs differ significantly in complexity and cost—gas requires certification.
Oven failures rarely create the urgency of fridge breakdowns; you have time to evaluate options carefully.

Oven Lifespan & Age Considerations
Electric ovens typically last 10–15 years with regular use. Gas ovens often reach 12–18 years because they lack complex electronic controls. Lifespan depends on frequency of use, cleaning practices, and component quality. Melbourne homes use ovens less intensively than other appliances, allowing some machines to reach 20 years despite age.
At 12 years, both gas and electric ovens enter the high-risk zone. At 15 years, replacement becomes increasingly attractive. At 18 years, continuing to repair is rarely justified unless work is minor.

Common Oven Repairs & Costs
Melbourne repair callouts for ovens cost $100–160 before parts. Understanding common failures helps assess economic viability. Important note: gas oven repairs require licensed gas fitters—only use qualified technicians.
| Repair Type | Cost Range (AUD) | Typical Age Affected | Repair Viability |
|---|---|---|---|
| Heating element (electric) | $100–250 | 8–15 years | High |
| Thermostat replacement | $150–300 | 8–14 years | High |
| Door seal/gasket | $50–150 | 6–12 years | High |
| Igniter (gas) | $100–200 | 8–15 years | High |
| Control board/module | $200–400 | 10–16 years | Moderate |
| Fan motor (convection) | $150–300 | 10–15 years | Moderate |

New Oven Costs in Melbourne
The Australian oven market divides into freestanding and built-in categories. Most replacements are freestanding 60cm units. Prices range from budget $500 to luxury $5,000+, with most families choosing mid-range models ($800–2,000).
| Oven Type | Price Range (AUD) | Typical Features | Installation Cost |
|---|---|---|---|
| Basic freestanding electric | $500–900 | Single cavity, standard controls | $100–200 |
| Standard freestanding electric | $900–1,500 | Single or dual cavity, convection | $100–200 |
| Premium freestanding gas | $1,000–2,000 | Gas cooktop + electric oven combo | $150–300 |
| Built-in electric oven | $1,000–2,500+ | Professional features, stainless | $300–500+ |

Gas vs Electric Oven Considerations
If replacing an electric oven with gas (or vice versa), factor in conversion costs. Gas oven installation requires licensed gas fitter ($300–500). Converting from gas to electric requires electrician work ($400–800). Most Melbourne homes favour electric for simplicity and safety, but gas remains popular in certain suburbs.
Gas ovens offer faster heat response and lower running costs. Electric ovens are safer and more reliable long-term. Combination units (gas cooktop with electric oven) offer flexibility but cost more initially.
| Fuel Type | Installation Cost | Running Cost/Month | Maintenance | Safety |
|---|---|---|---|---|
| Electric only | $100–200 | $15–25 | Lower | Highest |
| Gas only | $150–300 | $12–20 | Moderate | Requires venting |
| Gas cooktop + electric oven | $200–400 | $20–30 | Moderate | Mixed |
| Induction cooktop + electric oven | $300–500 | $18–28 | Lowest | Highest |

Decision Framework: Repair vs Replace
Apply this framework systematically. Ovens are lower-urgency repairs than fridges, giving you time to think clearly.
- Get a repair quote from a qualified technician.
- Research equivalent replacement oven cost.
- If repair exceeds 50% of replacement, proceed with replacement.
- If machine is 12–15 years old, reduce threshold to 40%.
- If machine is over 15 years, replace unless repair is under 20% of new cost.
- For gas ovens, ensure technician is licensed—unlicensed work voids warranties and creates safety risks.
| Oven Age | Repair Cost Threshold | Typical Recommendation |
|---|---|---|
| Under 7 years | Repair if under 50% of new | Usually repair |
| 7–12 years | Repair if under 45% of new | Usually repair if cost favourable |
| 12–15 years | Repair if under 35% of new | Lean towards replacement |
| 15–18 years | Repair if under 20% of new | Usually replace |
| Over 18 years | Do not repair | Replace immediately |

Convection vs Standard Oven Features
When replacing, consider whether you need convection cooking. Convection ovens circulate hot air, reducing cooking time by 15–25%. They cost $100–300 more than standard models. If you bake regularly, convection justifies the extra cost. If you rarely bake, standard ovens suffice.

Troubleshooting Common Problems
| Problem | Likely Cause | Fix |
|---|---|---|
| Oven won’t heat or heats unevenly | Failed heating element (electric) or igniter (gas), or thermostat failure | Element replacement ($100–250) is straightforward on electric ovens under 12 years. Gas igniter failure ($100–200) requires licensed technician. Thermostat failure ($150–300) is moderate complexity. These repairs are justified on machines under 12 years. |
| Door won’t close properly or seal leaks heat | Damaged door gasket or hinges misaligned | Door seal replacement ($50–150) is one of the most cost-effective repairs. Justifiable at any oven age. If hinges are damaged, replacement becomes more expensive ($150–300). |
| Fan noisy or not working (convection oven) | Fan motor wear, blockage, or bearing failure | Fan motor replacement ($150–300) is reasonable on machines under 12 years. Check for obstructions first—lint and food particles often jam fans (free fix). |
| Control panel buttons unresponsive or display dark | Control board failure or electrical connection issue | Control board replacement ($200–400) is expensive. On machines over 12 years, replacement is more economical. Younger machines may justify the repair if no other issues exist. |
When to Call a Professional
Use only licensed technicians for gas oven repairs. Unlicensed work creates safety hazards (gas leaks, incomplete combustion) and voids warranties. Melbourne has many qualified gas fitters—request credentials before work begins.
For electric ovens, most repairs are simpler and can be handled by general appliance technicians. Still request references and written quotes.
Ask technicians directly: ‘Will this oven likely fail again soon?’ Experienced professionals can assess whether other components are near failure. Use this information when deciding whether repair justifies the risk.
Tips & Gotchas
Frequently Asked Questions
Is it worth fixing a 13-year-old oven?
It depends on repair type. Thermostat ($150–300) or element ($100–250) repairs are reasonable on 13-year-old ovens. Control board failure ($200–400) should trigger replacement consideration. Gas igniter failure ($100–200) is justified on 13-year-old machines if nothing else is wrong. Get a comprehensive assessment before committing.
How much do oven repairs typically cost in Melbourne?
Expect $100–160 for callout assessment. Most repairs range $150–400 depending on component. Element or igniter work costs $100–250. Thermostat replacement runs $150–300. Control board work reaches $200–400. Seal replacement is the cheapest at $50–150. Labour plus parts typically total $250–500 for straightforward fixes.
Can I convert my gas oven to electric?
Yes, but it’s expensive. Requires licensed electrician to install circuit, condition wiring, and connect oven ($400–800). Combined with new oven cost ($900–2,000), total conversion can reach $1,300–2,800. Only worthwhile if your oven is already failing and you strongly prefer electric. Most people replace with equivalent fuel type to avoid conversion costs.
What’s the best oven brand in Australia?
Fisher & Paykel, LG, and Samsung lead reliability and features. Bosch offers premium options. Westinghouse provides budget-friendly choices. All are widely available in Melbourne. Prioritise convection capability, digital temperature control, and warranty over brand name.
Should I buy a self-cleaning oven?
Self-cleaning ovens heat to extremely high temperatures to burn off food residue. They use extra energy ($10–20 per cycle) and can stress components, shortening lifespan. Manual cleaning with appropriate products is more economical. Skip self-cleaning unless you rarely clean and time is more valuable than money.
How often should ovens be serviced?
Annual service before winter cooking season is ideal, especially for gas ovens. This includes checking ignition, thermostat accuracy, and seal integrity. Annual service costs $100–150 but extends lifespan and prevents emergency failures. Melbourne’s mild winters mean less frequent use for some households—assess your situation and adjust accordingly.
Is it safe to use a 20-year-old oven?
Electric ovens are generally safe at 20 years if elements and controls function. Gas ovens at 20 years carry higher risk—combustion efficiency declines, safety controls degrade, and leaks become more likely. Have any 20-year-old gas oven inspected by a licensed gas fitter before continued use. Budget for replacement within 1–2 years to avoid emergency failure.
