- Use the quick checklist below to decide before you call a technician.
How Long Should an Oven Last?
Most manufacturers rate ovens for 10‑15 years of regular use. Appliance lifespan the period an appliance remains functional and safe without major overhauls depends on usage frequency, cleaning habits, and the type of fuel (electric vs gas). A well‑maintained gas oven often outlives its electric counterpart by a year or two because the heating elements are simpler to replace.

Decision Matrix: When Repair Beats Replacement
Use this quick mental checklist. If more than one condition applies, replacement is likely the smarter move.
- Age factor: If the oven is ≤8 years old, repair is generally cheaper.
- Cost ratio: If the quoted repair exceeds 30% of a comparable new oven, consider buying.
- Recurring issues: Multiple breakdowns within 12months suggest underlying wear.
- Energy savings: Newer models carry a higher energy efficiency rating that reduces electricity or gas consumption rating, potentially saving NZ$50‑NZ$150 per year.
- Warranty status: If the original warranty has expired, a new unit often includes a 2‑year guarantee, reducing future risk.
Hidden Costs You Might Overlook
Beyond the sticker price, factor in these expenses.
- Installation service: Gas ovens require a certified plumber, adding NZ$120‑NZ$200.
- Disposal fee: Council bulk‑waste charges range NZ$30‑NZ$60.
- Energy consumption: An older 2.4kW electric oven may use 15‑20% more power than a 2025 Energy Star model.
- Insurance premium: Some home insurers lower premiums for newer, safer appliances.
DIY Repair vs Professional Service
If you’re handy, minor tasks like replacing a door gasket or cleaning a faulty igniter can be DIY‑friendly. DIY repair homeowner‑performed fixes using basic tools and replacement parts can shave $50‑$100 off the bill. However, working with gas components or electronic control boards without certification is illegal in NZ and risky.
Professional technicians bring:
- Warranty on labour (usually 12months)
- Safety compliance for gas connections
- Access to OEM parts that may be scarce for older models
When in doubt, request a written estimate before any work starts.
Quick Decision Checklist
- Is the oven less than 8years old?
- Is the repair estimate under NZ$300?
- Will the fix restore all original functions (including self‑clean, convection, etc.)?
- Do you have a reliable, certified technician nearby?
- Are you comfortable with potential DIY steps?
If you answer ‘yes’ to most, go ahead with the repair. Otherwise, start shopping for a new oven.

| Warranty coverage | Typically 12months on labour | 2‑year manufacturer warranty |
| Potential hidden costs | May need part upgrades, future repairs | Installation, disposal, possible upgrades |
| Environmental impact | Less waste, lower embodied carbon | Higher upfront carbon, but offset by energy savings |
