A091801 Genuine Microswitch for Ariston Appliances, Ariston Replacement Micro Switch, Indesit Whirlpool Group

Genuine Ariston microswitch A091801. Microswitches are small snap-action switches that tell an appliance when a door is shut, a lid is down or a part has moved into position. The stock record doesn't name the appliance this one comes from, so please compare A091801 with the number on your old switch or your model's parts list. If you're unsure, send us your Ariston model and product numbers.

What happens when an Ariston microswitch fails

Because a microswitch is often a safety interlock, a failed one can stop an appliance in its tracks. You might find the appliance won't start, stops partway through, shows a door or lid error, or a light or fan won't switch on or off when it should. A switch that sticks closed can be just as troublesome as one that won't close. With the power off, a multimeter will show whether the switch opens and closes cleanly when the lever is pressed.

Fitting the microswitch

Turn the appliance off at the wall or isolating switch before removing any panels. Note which terminal each wire connects to, as microswitches usually have common, normally open and normally closed terminals. Swap the wires across one at a time, mount the new switch so its lever is pressed fully by the actuator, and test the operation before closing up.

Questions about this part

Can I use any microswitch with the same terminals?

A generic switch might physically fit, but the rating, lever shape and mounting need to match too. Fitting the genuine A091801 keeps the original fit and rating.
