Multimeter, Hand Tool, Wire Connector, Work Gloves, Check Continuity Throughout Your Circuit If one of your devices isn't working properly, it could cause a wire break. Checking for continuity allows you to test whether current is being done through the wire. First unplug the appliance. To avoid electric shock, all continuity checks must be performed with the appliance unplugged. If electrical components are connected to wires, the easiest way to check for continuity is through the entire circuit, as both ends of the circuit will be connected to the control board. Access the Dashboard. Trace the wires back to the board and measure the resistance through the circuit you want to check. For example, the resistance of a baked element through this range is 15 ohms. If you measure 15 ohms then you know all wires have continuity. You can find the correct resistance value in the device's technical sheet, or measure the resistance directly on the device.
If the meter shows a 1 in the leftmost digit, or a 1 on some meters OL, you have an open circuit and the power isn't going all the way through. You either have broken wires or damaged electrical components.
Checking for Continuity of Individual Wires Before replacing this part, you will need to check individual wires for broken continuity. To check the continuity of a series of wiring, disconnect both ends of the wire. Set the multimeter to use the tone to check for continuity. Put one meter of wire on one end of the wire and the other wire on the other end of the wire. If the wire has continuity, the meter will emit a tone and show resistance near 0 ohms. After checking the continuity of this wire, you should also check the continuity of this wire to the metal frame. Occasionally, exposed or damaged wires can come into contact with metal cabinets on equipment, dissipating potentially dangerous currents that could result in electric shock or death. If you see continuity between the wires and the metal frame, do not replug the unit until all wires have been repaired. Fixing Broken Wires Now, if you see something like this (broken wire), obviously you know it's something you want to fix.
You can fix the wire by splice in that location. Cut the wires and strip 1/4 inch of insulation from the ends of the wires. Reconnect the wires using a suitable wire nut or connector. After repairing the wires, make sure no bare wires are exposed. If the wires are used in a stovetop or oven, use a properly heated ceramic wire nut to connect the wires. Ceramic wire nuts with a temperature rating of 200 degrees Celsius are suitable for most ranges and ovens. If the splice will short the wire and no longer fit, the splice will need to be made on the new correctly rated wire. Always check the continuity of the repaired wires before reassembling the device.
