What Does Error F18 Mean?

The Fisher & Paykel oven error F18 signifies a fault in the convection element circuit, which can lead to slow or no temperature rise during fan-assisted baking modes. This problem often stems from a faulty convection heating element, loose connections, or issues within the wiring harness. If the oven displays F18, it indicates that the oven may struggle to maintain proper heating, resulting in unsatisfactory cooking results.

Common Symptoms:

  • Oven display shows F18
  • Slow or no temperature rise in fan/convection modes
  • Fan‑assisted baking functions fail to heat effectively

Possible Causes

  • Faulty convection (ring) heating element (medium)
  • Loose or burnt connections at convection element terminals (medium)
  • Wiring harness damage near fan housing (medium)
  • Faulty convection element relay or control board component (low)

How to Fix Error F18

DIY Fix Basic checks and reset

  1. Turn off and completely cool the oven
  2. Switch off power at the breaker for 1–2 minutes then restore power
  3. Attempt to run a basic baking cycle to see if F18 clears

Technician Only Inspect and repair convection heating circuit

  1. Disconnect oven from mains power
  2. Remove the back panel and/or interior cover to access the convection (ring) heating element
  3. Visually inspect element for breaks, cracks, and burn marks
  4. Check continuity of the convection element with a multimeter
  5. Inspect wiring harness and terminal connections for heat damage or looseness
  6. Replace the convection heating element if open or damaged
  7. If element and wiring are good, test/replace the control board’s convection relay and related components

Parts needed: Convection (ring) heating element, Control board or relay components, Wiring harness/terminal connectors

🛑 When to Call a Pro:
  • If you are uncomfortable working with mains voltage and internal components
  • If you lack tools to safely test continuity and access heating elements
  • If replacing the heating element does not clear F18
