Fisher & Paykel Induction Cooktop: not heating
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.
Important Tips for Fisher & Paykel Models
- Fisher & Paykel induction cooktops display U when no suitable cookware is detected and will not heat until suitable pan is centered.
Possible Causes
Incompatible or improperly detected cookware
How to Identify: Induction cooktop powers on but does not heat, display may flash U; a magnet will not stick to cookware or pan is too small/not centered on zone.
Part: Cookware and pan detection system
Cookware too small or misaligned for cooking zone
How to Identify: Cookware fits poorly or is smaller than recommended minimum size causing cooktop to not register cookware.
Part: Cookware location relative to induction coil
Control lock, safety lock or child lock activated
How to Identify: Controls are unresponsive or heating doesn’t start with normal button responses, lock symbol may be visible.
Part: Control panel lock function
Overheating or thermal protection auto shut-off
How to Identify: Cooktop shuts down heating after extended high use or vents blocked; may restart after cooling.
Part: Internal thermal sensor / cooling system
Internal component fault (coil, sensor, control board)
How to Identify: Unit powers on but still doesn’t heat with correct cookware, no user-fix steps work, possible error codes.
Part: Induction coil or electronic control board
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.
