Answer to continue safely

Is it safe to keep using?

No. The cooktop cannot be used while F15 is active because the control boards cannot communicate. No heating zones will function.

Can I reset the code?

Yes. A power cycle may restore communication if the issue is an intermittent connection. If the cable or circuit is damaged, a reset will not help.

When to stop immediately?

Stop if you notice: Stop if you see any signs of moisture or liquid inside the cooktop through vents or gaps., Do not attempt to open the cooktop housing to access the ribbon cable..

Symptoms You May Notice

F15 displayed on panel

The cooktop shows F15 and all cooking zones are completely disabled.

Touch controls unresponsive

No touch inputs are recognized because the UI board cannot communicate commands to the main board.

Display shows partial or garbled information

Before fully failing, the display may show random characters or incomplete zone information.

Cooktop turns off mid-use

The unit suddenly stops working during cooking as the communication link drops.

Possible Causes

1

Loose ribbon cable connection

The flat ribbon cable connecting the UI board to the main control board has come partially unseated from its connector.

Requires Professional
2

Corroded communication connector

Moisture or a spill has corroded the pins on the inter-board connector, interrupting the data link.

Requires Professional
3

Failed communication circuit

A power surge has damaged the serial communication IC on the UI board or the main control board.

Requires Professional

Safe Checks You Can Do

These checks are safe for homeowners. No disassembly required. Do not remove panels or access internal components.
  1. 1

    Power cycle the cooktop

    Turn off the breaker and wait three minutes before restoring power to allow both boards to fully reset.

    Three minutes is important here because communication protocols need a full timeout before reinitializing.

  2. 2

    Repeat the power cycle

    If F15 returns, cycle the breaker off and on two more times with one-minute intervals.

    Intermittent cable connections sometimes reseat during the thermal contraction of a power-off period.

  3. 3

    Document recent events

    Note whether there was a recent power outage, storm, or liquid spill that may have triggered the fault.

    This information will help a technician diagnose the root cause faster.

When to Call a Professional

Contact a qualified technician if:

  • The F15 code persists after three or more power cycles.
  • The display showed garbled characters before the F15 code appeared.
  • A recent power surge or lightning event occurred shortly before the fault.
