Fix Bertazzoni Gas Stove Keeps Clicking

A Bertazzoni gas stove that keeps clicking — even after the burner lights, or with every burner off — is almost always an electrical short at the igniter, not a gas fault. These Italian ranges use brass burners and a spark module that fires the igniters, and moisture or residue at the electrode is the usual trigger. Here's how to narrow it down.

Start here#

Most likely: moisture on the igniter electrode. Water from a boil-over, a spill, or cleaning bridges the spark electrode and creates a short that makes it click continuously. Dry the burner area thoroughly — pull the cap and head, blot up moisture, and let it air out or use a fan. If it still clicks after it's fully dry, food residue or a stuck switch is next.

Stop the clicking right now#

Unplug the stove or turn off the breaker — this stops the clicking immediately. You can still light the burners manually with a long-reach lighter until it's repaired.

Ranked causes at a glance#

Working through each cause#

1. Moisture on the igniter (most common)#

Liquid on the spark electrode from a boil-over, spill, or wet cleaning shorts the ignition circuit and it clicks nonstop. Remove the burner cap and head, blot up any visible moisture, and let the area dry completely — a fan across the burners speeds it. Avoid cooking on that burner until the clicking stops, since the moisture should evaporate within a couple of hours.

2. Food debris around the igniter (common)#

Grease and food residue built up around the electrode can conduct electricity and trigger the spark even when the switch isn't engaged. Clean around the electrode base with a dry cloth or an old toothbrush, and clear any carbonized food bridging the gap between the electrode and the burner. Keep water away from the electrode while cleaning.

3. Stuck igniter switch (occasional)#

Each Bertazzoni burner knob has a micro-switch that fires the spark in the light position, and if that switch sticks on — from grease, wear, or a tired spring — the igniter fires continuously no matter where the knob sits. Clicking the affected knob rapidly between light and off several times can free a stuck switch. If it keeps sticking, the switch needs replacement.

4. Faulty spark module (less common)#

The spark module distributes voltage to all the igniters, and an internally shorted module can fire one or all channels continuously. If drying and cleaning don't stop the clicking, the module is the likely culprit — it's a single part usually behind the back panel or under the cooktop. Confirm the electrodes and switches are clean and dry first, since the module is the more involved replacement.

5. Damaged igniter wiring (rare)#

Frayed or heat-damaged wiring between the spark module and an electrode can short and drive continuous sparking. Check for wires touching metal surfaces, melted insulation near the burners, or rodent damage. Repair or replace the affected wiring so it isn't grounding against the chassis.

The short version#

• Moisture — most common; dry the burner area fully.
• Food debris — common; clean the electrode base dry.
• Stuck switch — occasional; cycle the knob, replace if it keeps sticking.
• Spark module — less common; internally shorted, replace the module.
• Damaged wiring — rare; find and repair the short.

What the repair usually involves#

Most clicking repairs are cleaning and drying — the fix for the top two causes — and only move on to replacing a stuck igniter switch or the spark module if the clicking survives a fully dry, clean burner. A technician confirms which channel is firing and replaces the switch or module, then verifies the igniters fire only on demand.

Keeping it from coming back#

Wipe up boil-overs and spills promptly, let the burner area dry before cooking, and keep water off the electrodes when you clean — most repeat clicking on a Bertazzoni traces back to moisture or residue rather than a failed part. Extended clicking does wear the module and switch, so it's worth resolving.

When to call a professional#

Call a technician if the clicking continues after the burner is fully dry and clean, if a micro-switch or the spark module needs replacing, or if you find damaged wiring near the burners. The cost depends on whether it's a switch or the module plus labor, and a tech can confirm before starting.
