Now begins the dangerous portion of the project. Don’t forget you will be working with 120V of electricity. DO NOT PLUG IN THE APPLIANCE WITH ANY LOSE WIRES EXPOSED. You may have a need to test portions of the system while some wires aren’t connected. Always cover exposed wires with a wire nut before plugging in the coffee roaster.
You will need to determine how you will wire the motor before you begin. You start by tracing the circuit from the old wiring. The electricity flows from one wire in the power cord through the system and back out the other wire. The small prong on the power cord is the hot wire and the large prong is the neutral wire.
The power from the wall socket isn’t enough to start the rotation of the motor. Bread maker motors require a start capacitor. You will need to examine your configuration to determine where your start capacitor is and how it should be wired. This is where the pictures come in handy.
Here are some examples:
I can’t tell you how to wire your motor since they will vary. That’s the downside of re-purposing something.
Go ahead and wire in your motor. Again, make sure any loose wires are covered with a wire nut.
When you plug it in it should start immediately. If you just hear a humming sound then you haven’t connected the capacitor correctly. It may take a couple of tries to get it right.
