New A/C wiring question
« on: July 21, 2008, 05:09:28 PM »
I also have a A/C wiring question.  I purchased a Dayton (1) 4M223G condenser fan motor that has 4 wires plus a ground while the motor I'm replacing has 3 wires.

New has: Brown, Brown/White stripe, Black, Purple
Old has:  Brown, Yellow, Black

how do I wire the new motor into the A/C unit and capacitor?

Thanks in advance,
Bryan

That's not really a fair question...we would need to know how the A/c unit is wired. Colors mean nothing on different motors.  Also, be sure the motor you bought uses the same capacitor as the old one. Often they change, and it is noted inside of the box the motor came in. In your case, the diagram is clearly on the side.

Use the brown and brown and white wires on a new capacitor for the new motor. Hook black to where black was and purple to where yellow was. OR if you want it like it was,using the old capacitor, just tape off purple and do not use. Black will go where black went. Brown will go where brown went. Brown with white stripe will go where yellow went. Simple

Thanks, I will try wiring it to the old capacitor and taping off the purple.  The new capacitor only has 2 terminals while the old capacitor had 3 (labeled - Fan, C, Herm)

By using the old capacitor I don't have to figure out what to do with the 2 wires coming off a compressor terminal box that go to the old capacitor.  Coming off the terminal box, red went to C and Yellow went to Herm on the old capacitor.  If I used the new capacitor I'd have more to figure out.

Thanks again....

The old capacitor MUST have the same rating as the new capacitor in order to run right. For instance:if your old motor used a 5mfd cap and the new motor uses a 5mfd cap then you are ok. Why buy a new car and install your old spark plugs in it though? What I would do is hook the new capacitor to the new motor with the 2 brown wires.That leaves 2 wires. Hook the black one on the contactor so when it pulls down the motor will kick in. That leaves one wire. Hook it on the common terminal of the old capacitor to feed back to source.

Fact when you change the motor, always change the cpacitor. Your old one is a "dual-capacitor" it serves both the Compressor and fan that is why H C F Hermetic (compressor) Common, Fan

 I also had this same problem.  I hooked the new cap as described, but my fan spins the opposite way. pulls air in instead of blowing out. Any ideas on what i did wrong?

 As the old T.V. Commercial use to say, R I F (reading is fundamental).
There is a wiring diagram on the side of this motor.  :)

It is very easy to reverse the motor. Look on the motor . Their should be a quick connect plug you yank apart and flip or a set of 2 wires(usualy orange and yellow) with male and female connectors. Put orange female to yellow male and yellow female to orange male and bada bing bada boom it goes da otha way. It is hard to screw up.  Look on the lable as mr Icehouse says. :2funny:
