Kitchenaid Cooktop: igniters sparking continuously

Professional Repair Guide

What is this symptom?

Experiencing continuous sparking from the igniters on your KitchenAid gas cooktop? This issue occurs when the igniters keep clicking even after the burners are lit or the knobs are not in the ignite position, indicating a malfunction that may require troubleshooting.

Urgency: Medium

Important Tips for Kitchenaid Models

Moisture in switches and downdraft vent airflow issues are specifically noted in KitchenAid official troubleshooting documentation as causes for ongoing sparking.

Possible Causes

Moisture around igniter switches or ignition area

How to Identify: Sparking often occurs after cleaning, spills, or high humidity; may decrease once dried. Drying with cool air or waiting can stop sparks temporarily. Moisture in control knob area can be felt or seen.

Part: ignition switch, wiring near knob shafts

Faulty or shorted spark ignition switch

How to Identify: Igniters spark continuously regardless of knob position; multimeter shows switch has continuity at all settings indicating stuck closed contacts.

Part: spark ignition switch (under control knob)

Faulty spark module (ignition control module)

How to Identify: All switches and igniters are confirmed good yet sparking continues; module does not stop sending pulses after ignition.

Part: spark module

Misaligned or dirty igniter electrodes or burner components

How to Identify: Visible debris, grease, or misaligned burner cap/electrode causing erratic sparking; cleaning often reduces unwanted clicking.

Part: spark electrodes, burner heads

Downdraft vent affecting flame sensing (brand-specific environment issue)

How to Identify: Continuous sparking when a downdraft vent is on high; reducing vent speed or increasing flame setting stops excessive sparking.

Part: flame sensing circuits
