How to check Black and Decker 3-Cup Rice Cooker continuity

Introduction

The device's power cord breaks easily, stopping it from delivering power to the device. In this guide, we will test for power by using a voltmeter.

  6. How to check Black and Decker 3-Cup Rice Cooker continuity, Remove the Leg Screws: étape 5, image 1 de 1

    • Using a Phillips screwdriver, remove the 10mm long 7mm diameter Phillips-head screws from the inside of all four legs.

    • The smaller leg at the bottom is now loose and not attached to the device. Set it aside.

  8. How to check Black and Decker 3-Cup Rice Cooker continuity, Color the Wires: étape 7, image 1 de 2 How to check Black and Decker 3-Cup Rice Cooker continuity, Color the Wires: étape 7, image 2 de 2

    • Color coordinating wire groups make it easier to identify the wire groups during reassembly.

    • Inside the device, there are three junctions with wires joined by Phillips-head screws. The first is connected to two wires, and the other two are connected to three wires each.

    • Unscrew the screw at the junction near the opposite side of the device from the front panel.

    • Label each of the two wires at this junction with a single color of tape.

    Modifier

  9. How to check Black and Decker 3-Cup Rice Cooker continuity, Label the Second Wire Junction: étape 8, image 1 de 2 How to check Black and Decker 3-Cup Rice Cooker continuity, Label the Second Wire Junction: étape 8, image 2 de 2

    • Unscrew the screw at the junction just clockwise from the button panel.

    • Label the three wires of this junction with tape of a second color.

    Modifier

  10. How to check Black and Decker 3-Cup Rice Cooker continuity, Label the Third Wire Junction: étape 9, image 1 de 2 How to check Black and Decker 3-Cup Rice Cooker continuity, Label the Third Wire Junction: étape 9, image 2 de 2

    • Unscrew the screw from the wire junction just behind the front panel.

    • Label the three wires at this junction with a third color of tape.

    Modifier

  11. How to check Black and Decker 3-Cup Rice Cooker continuity, Plug the Device into an Outlet: étape 10, image 1 de 1

    • During these steps, DO NOT touch the wires directly. You may be electrocuted.

    • Plug the device's power cord into a functioning outlet.

    Modifier

  12. How to check Black and Decker 3-Cup Rice Cooker continuity, Check the Voltage between the Wires: étape 11, image 1 de 1

    • Locate the two wires which are connected directly to the power cord. Unlike the other wires, they are sheathed in a particularly thick, dot-textured plastic.

    • Make sure the voltmeter is on and set to a setting beween 120 and 500V. For most voltmeters the proper setting for this is the 200V setting.

    • Attach one of the voltmeter's probes to the metal portions of each of the two wires connected to the power cord's end on the device

    • The voltmeter should read a number significantly above 20V. A reading between 100 and 150 V indicates that the device is getting enough power. A lower number indicates the power cord is broken.

Conclusion

This guide alters no parts of the device, so no reassembly is needed from these steps.
