Hi, is there any way to wire a blower motor for a split a/c unit to work in place of a worn out blower motor. The first picture is the wiring diagram of the Original Motor - - the YDK is the original motor. Original motor wire colors - - Black, Green, Yellow, Red, Orange, White. Can the motor in the second picture be wired to replace the original motor? ? The new unused motor wiring colors are: Black, White, Red, Brown, Gray, Yellow.

If so, please explain to me how and which wires to use in matching up colors.

Please HELP.

Anyone with electrical wiring knowledge - - can I make the second motor work in place of the old motor? ? ?

I cannot find an exact replacement new motor.

 

Help - any electrician? ? ?

 

Welcome to the forums.

I'm a tech and can't answer that question. The motors are not the same. Yours has multi speed windings while the one you want to stick in there use a pulse feedback system. I'd say the motors are not compatible with each other.

You can order that motor in the link below. I'm pretty sure they sell to the public.

I have talked twice with them on the phone this past week, and they do not have that motor - out of stock.

Thank you for a reply - - Is there any way to wire it in so that one or two speeds will work ? ? ?

Please let me know.

 

Here's another place for the motor.

Are you shore it not is the motor protection who is wrong? It is a kind of fuse releasing on high load = temp.

If you put a wire between OR and WH and the motor runs, it is the protective device who needs to be reset/replaced.

The capacitor may also be a source of trouble (4uF / 450V) you may try another rated at least 200V and with a value between 2 and 6 uF It may be one in a fluorescent tube armature.

 

The new motor are pretty different. and if it was mine I would have considered to take the chance of ruin it.

I would have started with some testing, probably it will run for full speed with power between wt and bk, but in worst case it burns. I would try to find something to test with a sudden protection, not sure it will help but I would have taken the chance.

A hair dryer on half power, and in series with the motor. It will limit the power (current) but a motor with no fan will easily start. If it runs OK, else ???

It is risky, and it is your choice, be careful!

 

The reason that I pulled the old motor was that it kept stopping. Then when I looked at it - - when it was removed, the bearings are all worn out. Much bearing powder around each shaft.
I pulled the second motor from another unused split air conditioning wall unit and was hoping that I could put it into my daughter's unit on her wall.
However, the size is the same and the shaft will fit, but it is the wiring diagram that worries me. Both motors came from wall mount split air conditioning units.
All have the same number of wires but there are two wires of different color and the diagram for wiring is different.
I was hoping to give my daughter a cool room to sleep in, with putting in this new unused motor.

I don't know what to do? ?

Any help would be welcomed.

 

The form factor of the motors is the same, but the internal wiring is completely different. My guess is that if you put power between black and white it will run at full speed; however that's a big guess. The other wires would be capped off.

It's just as likely that it will cause an error code or burn out the circuit board. The new motor is about 30% more powerful than the old one so it could overload some internal component. It also cannot be speed controlled so that might cause the unit not to work right, but it's usually better to err on the side of more fan in an AC unit.

Check out pattenp's link too. But if you've exhausted your search for an exact match the alternative is replacing the whole mini split unit, it's worth a shot. If you burn it up you're just back to replacement anyway.
