Turn off power to machine and have a 5/16" or 1/4" nut driver handy take off front door of machine. Take a rubber coated Screw driver and place across the terminals of the Capacitor to discharge any stored electricity. Cut wires for blower Black, Red, white, two browns one with white lines on it probably. Look inside machine and locate where bracket holds squirrel cage to air handler and there you will find either 5/16" or 3/8" screw remove pull bracket out. Then you will need a 1/2" socket and a crescent wrench. Remove screws for motor bracket that is attached to squirrel cage. Also you need to loosen the set screw that attaches blower wheel to motor. Apply wd-40 if needed to remove blower wheel from motor. Then install new motor on the flat part of the shaft comes through wheel attach set screw to motor shaft at that position. Install new cap that goes with motor. place entire housing of motor back into air handler and then follow wires that where previously cut back to either relays, sequencers, or fan timer board located in top section of air handler. Tighten everything up and turn power on and make sure air is coming out of vents. Then your good to go.
First I would suggest that you replace the start capacitor on your blower motor but if it is running for awhile that makes me wonder if the thermal overload is shutting your motor off. You can replace the start capacitor and then if it starts as it's supposed to and then shuts off you'll know the motor needs replaced also. I hope this helps you . THanks
inside the air handle there is a motor and a cage(squirrel). I am assuming this is the problem. The side that has the pilot light, take this cove off first, then the back cover. There is a switch so when you take the back cover off it opens the circuit. You will see a main board and to the left and behind is the motor and squirrel cage. I would kill power and then remove the bolts making sure I make the wires and where they go. Then just take the motor and cage out. You will need a allen wrench to remove cage, then replace motor. Hope this helps Tim
the blower motor is located in the air handler. It has a squirrel cage around it you will need a puller to pull the cage off you must first unthighten the set screw on the motor shaft. Then replace the motor with a motor that has the same specs as the one you took out.
Absolutely, however, you want to properly diagnose the reason why the fan is not running. It could be a less expensive part than the fan motor itself.
First, check to see if you have the proper voltage going to the motor. I believe your motor requires 240volts ac. If you do not have 240 volts, you have a control problem.......either the thermostat is failing to close R & G or your blower relay may have failed to close the contacts necessary for your fan to operate.
If you have the voltage, then you want try spinning the blower wheel with your hand. Does it spin freely? Is the motor warm/hot? If so, turn everything off for an hour or so. As soon as your energize it, try spinning the motor with your hand again.....if it spins freely with no resistance and then starts running by itself, the problem is the run capacitor (approx $20.00 depending on where you purchase it from). If there is resistance when you try to spin it, the problem is most likely with the bearings and you will need to replace the motor.......if you have to replace the motor, go ahead and replace the capacitor also, making sure it is properly "matched" with your new motor.
I hope you find this to be very helpful to you, moving forward. :-)
Hi there the main problem is the run capacitor on the side of the blower cage has gone bad. But you have replaced that.. The Next Problem is that one of the magnets inside the motor had demagnetized and is not allowing the cage to freely start But makes since that you can hand start the motion of the motor
Need A New motor Sadly to say But sometimes you can have them rebuilt for less than a new motor Any other questions just ask Bryan
