I have a Lennox HS16-461V-4P. The motor bearings died and I ordered a replacement motor. The old motor (GE) had two purple wires that went to and from the capacitor mounting in the unit. It also had orange and black wires that went to line voltage. The new motor (Emerson) only has three wires coming out of it not counting the chassis ground wire. The label on the motor reads:

Common org
Black line
Orange and purple on either side of the capacitor

Can this be right? Both the old and the new are 220 volt motors.

You should have got a new run capacitor with the new motor( I hope you did). If your motor has Black,White and brown. Brown will go to one side of the run capacitor, Black and White will go to the contactor and you will need to add a jumper wire from the side the white wire is on to the other side of the run capacitor.

I only have the following colors coming out of the new motor

Purple - label says goes to capacitor
Orange - label says goes to capacitor
Black - label says line
And the green ground wire

Old motor has:

Purple - diagram shows going to capacitor
2nd purple - diagram shows coming from capacitor
Black - diagram shows line
Orange - diagram shows line

I am somewhat corn-fused with this replacement motor... wiring on the old and the label on the new indicate that I can use the cap that I already have. With the old wiring, there was nothing else going to this cap but the purple wires from the motor...

If your black wire is on T2 on the contactor add a jumper wire from T1(opposite side of contactor) to the orange wire on the capacitor. Your black and orange is your 230 volt supply for your motor you need the common jumper for your run capacitor. Do not hook a second wire up on the same side of the capacitor with the purple. You almost got it, good luck. Black to one side of the contactor, purple one side of the capacitor,orange one side of capacitor, Jumper wire from orange side of capacitor to opposite side of contactor of the black wire.

Hi my name is Scotty. Welcome. This work is incredibly simple but incredibly dangerous. 240 volts at 40-50 amps will fire ball, light you up and blow up in your face so wear the proper protective gear and verify with a volt meter that everything is off even after you've turned off the supply breaker and opened the disconnect. A 50 amp circuit should turn off at 50 amps but sometimes it decides to hang around a little bit longer. This should scare you.
Work and protect yourself like you're going to short something out. Then you'll be better prepared.
Verify the direction and orientation of the fan blade and motor direction.
On a 4m223j replacement motor
4-WIRE motor (plus green ground) implemented in a 3-WIRE (plus green ground) CONFIGURATION. Yikes, Where's did all of the three wire motors go?
Why do they need to make something so simple, so hard
Draw this out on a piece of paper
Motor-Brown/white no connection insulate.
Motor-Brown to cap connection "C2".
Motor-Purple connection to cap connection "C1".
Line connection L1 to cap connection "C1".
Black to L2.
In theory 240v flows from L1 and L2 through to purple and black respectively.
L2 to Black is a direct connection.
L1 to Purple taps into Cap connection C1. This must be the charging lead for the Cap.
The brown must be the helper lead to get the motor started then dies off after the motor starts.
Installation: Turn house breaker off and disconnect the local disconnect.
Use a volt meter to verify no voltages present. Watch out the cap will still be hot with high voltage even after disconnected so wear dry leather gloves.
They're little high voltage batteries and will kill you.
Once you've connected everything (without the blade on) power it up and protect your eyes when you do it.
If nothing smokes and everything starts running in the correct direction. Then you've done it.
Disconnect everything all power and motor connections. Install fan blade, install connections then retest.
Or, just call someone to do it for you.
