How to Verify Fan Motor Wiring Connections: Checking the Motor and Capacitor Connections.

Wiring a Table Fan Motor with Capacitor

Electrical Question: I am rewiring a Table Fan Speed Control Switch.

I see you’re a contractor, so this question might be a little out of your ballpark, but might you help me figure out how to direct wire to a mechanical switch.

Thanks.

    Hi Ravi, Great Question.
    The motor capacitor is like a battery, because it stores electricity, so care should be taken when testing the capacitor. A tester can be used to check both lead wires for voltage, and to check for continuity, to see if the capacitor is faulty or not. If there is not any voltage or continuity then the capacitor is faulty.
    Electric motors can be tested to see if there is a short, or open condition within the motor windings which would indicate that the motor is faulty.
    Be sure to check the most common problems that can affect table fans, such as bad bearings, or bearings that need to be lubricated, and material that may get wrapped around the fan shaft which will prevent the motor from spinning normally.
    Also be sure there is voltage at the receptacle outlet, and the motor control switch is working properly.
    I hope this helps you,
    Dave

    I have a table fan, but today it is not working. How can I check its motor or capacitor to see if they are OK, or any other another reason.

    I have a Panasonic table fan. I opened the fan motor to replace the bearing but the connector attached at the coil winding is pulled out together. Is there any way to solder the connector back to the coil winding?

    I have a Airtech pedestal fan. It runs with a capacitor, but I’m not sure where these wires go not sure which 2 are the capacitor wires and not sure which ones are the switch wires. There are 2 blue wires, 1 white, 1 black, 1 yellow and 1 red. Airtech fan Model FS22-40.
