Ceiling fan diagnostics. How do I find out if my fan motor is working ok. Lights on bottom of fan work. help!

Changed the wall fan switch with a new switch. the lights on the bottom of the fan are controled by a separate wall switch; they work. This fan use to work find.Ceiling fan diagnostics. How do I find out if my fan motor is working ok. Lights on bottom of fan work. help!Do you have two switches, one for the lights and one for the fan? It sounds like you did not connect the wire from the switch to the fan. If you have seperate switches, the supply probably comes to the light switch and then a jumper is installed from the supply side of that switch to the fan switch. Check that out.. Maybe you just pulled the chain switch on the fan and turned it off? The fan motor did not go bad just setting there and since you did work in the box where the switches are..........There is where the problem is. One other thing, be sure that the jumper from the light switch to the fan switch is on the supply side. If you have it on the wrong terminal the fan will work when the lights are on but not indepenently.Ceiling fan diagnostics. How do I find out if my fan motor is working ok. Lights on bottom of fan work. help!you did not connect the wall switch back correctly or left something loose!! go back and check it again!!!Ceiling fan diagnostics. How do I find out if my fan motor is working ok. Lights on bottom of fan work. help!Check to determine if you have power to and from your fan with a voltmeter or test light. Check the connections to and from the fan. If you have a separate fan switch, make sure it is on and that there is power going in and coming out of it. Spin the fan blade by hand to determine if it spins freely. If the fan blade does not turn or does not spin freely, the motor might need cleaning or it might have a bad bearing. Also, the motor could have open or shorted windings. In this case, it would probably be more economical to purchase a new fan...Max
