Key Takeaways
- A cracked induction glass surface on a CI series cooktop often costs more to replace than a new unit.
- Gas manifold or valve failure on an older CG series unit is a safety and cost concern.
- Induction power board failures at 10+ years are expensive and signal broader electronic aging.
- Any cooktop fault involving gas leakage or arcing must be addressed immediately — repair or replace without delay.
The Bottom Line
Cracked glass, failed induction electronics, or gas valve faults on a 10+ year Fisher & Paykel cooktop are clear signals that replacement is safer and more economical than repair.

Fisher & Paykel cooktops — the CG gas series and CI induction series — are typically the longest-lived appliances in the kitchen. But certain failure modes make repair uneconomical or unsafe. Knowing the difference between a worthwhile fix and a replacement trigger is essential, particularly when gas safety is involved.Replacement Signals
| Warning Sign | Why It Matters |
|---|---|
| Cracked induction glass surface (CI series) | Glass surface replacement is labour-intensive and the part cost alone often exceeds 60–70% of a new cooktop's retail price. |
| Induction power board or inverter failure at 10+ years | Power electronics are expensive; on an older CI unit, the remaining zones and control board are aging in parallel. |
| Gas valve or manifold failure (CG series) | A faulty gas valve is a safety hazard as well as a repair cost concern; on a 12+ year unit, manifold integrity throughout the cooktop should be evaluated. |
| Igniter module failure affecting multiple burners | Widespread igniter failure on a gas cooktop indicates moisture or corrosion in the wiring harness — a systemic problem, not an isolated part fault. |
| Control panel delamination or button failure | Touch control panels on older induction units are often discontinued; if the replacement panel is unavailable, the cooktop cannot be restored. |
Quick Decision Guide
The 50% rule is your primary tool: if a repair quote exceeds half the price of a current Fisher & Paykel CI or CG cooktop in a comparable configuration, replacement is the better financial decision. For induction models, also weigh the efficiency gain — current CI series cooktops transfer energy to the pan more efficiently than older generations, reducing cooking times and energy consumption. If your kitchen benchtop is due for an upgrade anyway, a cooktop replacement can be coordinated to minimise disruption and installation costs.The Escalation Pattern
Cooktops often present a false sense of reliability — they work until a significant component fails, at which point the fault is usually expensive. A CG gas cooktop that has had a burner cap replaced, then a spark module, then develops a valve issue is showing escalating wear. Similarly, a CI induction unit with one failed zone that later develops a second non-responsive zone is experiencing progressive power board degradation. Do not invest in repeated single-zone repairs when the underlying electronics are failing progressively. A pattern of two or more faults within 24 months on a 10+ year cooktop is a reliable replacement indicator.Replacement Buying Guide
- Measure your existing cutout dimensions carefully — cooktop cutout sizes vary by model and generation.
- Current CI induction series offers boost zones and bridge zone functionality not available on older units.
- Gas CG series cooktops now include flame failure safety devices on all burners as standard — a safety upgrade worth having.
- Consider switching from gas to induction if your power supply supports it — induction offers faster heat response and easier cleaning.
- Check that the new model's maximum zone diameter suits your cookware set before purchasing.
- Confirm compatibility with your rangehood clearance and ventilation requirements.
