What is this symptom?
If your Fisher & Paykel induction cooktop powers on but cookware remains cold, it could be due to incompatible cookware, a control lock, or overheating. Indicators like 'U' may appear when the unit fails to heat. Understanding these common issues can help you troubleshoot effectively.

- Fisher & Paykel induction cooktops display U when no suitable cookware is detected and will not heat until suitable pan is centered.

DIY Solutions
Verify and Use Compatible Cookware
- Place a magnet on the base of each pot/pan; if magnet doesn’t stick, cookware is incompatible.
- Use cookware with a consistent magnetic base and appropriate diameter matching the cook zone size.
- Center the compatible pan on the induction zone before starting heat.
Disable Control Lock / Child Lock
- Locate the lock/key symbol on the control panel.
- Press and hold the lock button to deactivate the lock.
- Confirm lock indicator disappears and try selecting heat again.
Allow Cooktop to Cool Down
- Turn off the cooktop completely.
- Ensure surrounding area and vents are clear of obstructions.
- Wait for unit to cool then power on and try cooking again.
