A/401/02 Genuine Gas Oven Micro Switch for ILVE Gas Ovens and Upright Cookers, Oven Ignition Microswitch

A/401/02 is ILVE's genuine micro switch for gas ovens, found in ILVE gas ovens and upright cookers. ILVE's A/401 numbers cover the ignition micro switches, and this one is recorded for the gas oven. It's the small switch that tells the ignition when to spark as you operate the oven control. No models are on file for it, so match the number on your old switch or parts list before ordering.

Gas oven not sparking or clicking constantly

When you push in and turn the oven control, the micro switch closes and signals the spark generator to fire the oven igniter. Once you let go, the switch opens and the clicking stops. A faulty switch either won't close, so the oven gets no spark and won't light, or stays closed, so the ignition keeps clicking even with the oven off. Moisture and grease can cause intermittent faults that come and go. Check the igniter and its lead as well, as a cracked electrode gives similar symptoms.

Fitting the oven micro switch

Isolate the power at the wall and turn off the gas supply before opening the control panel. Work on a gas cooker must be done by a licensed gas fitter. Photograph the switch wiring and how the switch sits on the oven control, transfer the connections one at a time and make sure the switch actuates cleanly as the knob turns. Test the oven lights and the clicking stops.
