Kitchenaid Induction Cooktop: temperature sensor failure

Professional Repair Guide

What is this symptom?

Experiencing temperature sensor failure on your KitchenAid Induction Cooktop? This issue often manifests as sensor error codes like F8, indicating that the cooktop is unable to regulate or maintain cooking temperatures. Users may notice that cooking zones shut down or display errors after extended use, pointing to possible internal sensor malfunctions rather than cookware issues.

Urgency: Medium

Important Tips for Kitchenaid Models

  • F8 error code specifically linked to temperature sensor malfunction and overheating issues on KitchenAid induction cooktops.

Possible Causes

Internal temperature sensor malfunction

How to Identify: Induction zone shows specific error (e.g., F8 code when temperature rises or during prolonged heating; cooktop fails to regulate heat properly. (

Part: Temperature sensor/thermistor inside cooking zone module

Overheating due to blocked ventilation

How to Identify: Cooktop feels unusually hot externally, fans not running or air holes obstructed; frequent sensor errors after extended use. (

Part: Cooling fan/airflow passages

Loose internal wiring

How to Identify: Intermittent sensor errors, cooktop functions erratically; possible burning smell or sparks noted by some DIY discussion. (

Part: Wiring harness to sensor/control board

Control board malfunction

How to Identify: Sensor errors persist after cleaning and resets; other zones or controls behave unpredictably. (

Part: Main control board/PCB

DIY Solutions

Power Reset to Clear Temporary Errors

Easy 5 minutes
  1. Turn off power to the cooktop (breaker or unplug).
