Jennair Cooktop: error code F47

Professional Repair Guide

What is this symptom?

If your Jennair Cooktop displays error code F47, it may indicate a communication fault between the user interface and the main control board. This issue often leads to multiple burners failing to function during use or startup. Power cycling the cooktop may not resolve the error, indicating a more serious problem that requires attention.

Urgency: Medium

Important Tips for Jennair Models

  • Official JennAir documentation states F47 indicates a problem with cooktop power control board, user interface (touchpad), or associated wiring. (
  • Community cases indicate F47 can persist on induction cooktops when interface and control boards lose communication, requiring board replacement. (

Possible Causes

Communication fault between user interface (touch/DI display) and main control/power board

How to Identify: F47 persists after power reset; error appears on display; some burners unresponsive

Part: User interface board & power/control board

Faulty wiring or connector between control board and sensors/burner modules

How to Identify: Error remains after reset, visible damage or loose connectors under cooktop; intermittent burner effectiveness

Part: Wiring harness/connectors

Burner temperature sensor or induction coil/module failure

How to Identify: Specific burners consistently show F47 while others function; visible sensor fault codes

Part: Temperature sensors or induction coils/modules
