That may mean a set of switches or an assembly carrying more than one switch, and our records don't confirm which. Microswitches are small snap action switches that sense the position of a door, lid, knob or lever. Check the number A091991 and the layout of your old part before ordering, as the appliance isn't on file.\u003c\/p\u003e\n\u003ch2\u003eWhat microswitches do and how they fail\u003c\/h2\u003e\n\u003cp\u003eA microswitch flips over with a tiny movement of its button or lever, so the appliance knows when a door is shut, a knob has been pushed or a part has moved into place. Thousands of operations wear the internal spring and contacts, and heat or moisture can corrode the terminals. A failed microswitch can stop the appliance starting, halt it part way or bring up a door or lock error. On gas cooktops, a stuck ignition microswitch can make the igniters keep clicking. A multimeter check across the terminals confirms the fault.\u003c\/p\u003e\n\u003ch2\u003ePart details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine Ariston part A091991\u003c\/li\u003e\n\u003cli\u003eListed as microswitches (plural)\u003c\/li\u003e\n\u003cli\u003eSnap action switches that sense position\u003c\/li\u003e\n\u003cli\u003eAppliance and switch count not on file, compare with your old part\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eReplacing microswitches\u003c\/h2\u003e\n\u003cp\u003eSwitch off at the wall or circuit breaker before you start, and use a licensed electrician for hard-wired appliances. If the switches sit on a gas cooktop, have a licensed gas fitter do the job, as the burners and gas rail may need to come out. Photograph the wiring and the way each switch is mounted, since the lever must line up exactly. Fit the new part and test every function it controls.\u003c\/p\u003e\n\u003ch2\u003eQuestions about this part\u003c\/h2\u003e\n\u003ch3\u003eIs this one switch or a set?\u003c\/h3\u003e\u003cp\u003eThe manufacturer's description reads microswitches, but our records don't say how many are included or whether they come mounted on a bracket.
