Electrical Hazard Always disconnect the unit from the mains power supply before opening the base or handling electrical switches. 1.Disconnect and Invert Unit:Prerequisite.Unplug the machine. Remove the bowl, lid, and cutter blade, then turn the motor base upside down on a stable, padded surface to access the base plate. Verification: Confirm the power cord is physically disconnected. 2.Remove Base Plate and Locate Assembly:Remove the bottom housing screws and lift the base cover to expose the internal wiring and switch bracket. Verification: Locate the microswitch assembly (39217) situated where the mechanical safety rod engages. 3.Test and Swap the Switch:Multimeter required.Label the wire positions, remove the spade connectors, and test the old switch for continuity across the contacts while pressing the actuator button. If open circuit persists when pressed, unbolt the assembly and mount the replacement 39217. Verification: Test the new switch with a multimeter set to continuity; it should close/beep reliably when the actuator lever is depressed. 4.Reassemble and Test Mechanical Linkage:Secure the switch bracket, reconnect the wires securely, replace the base cover, and lock the bowl and lid onto the machine. Verification: Listen for a distinct, clear mechanical "click" as the lid locks into place before reconnecting mains power.
