Also, you should connect the new motor to run on low (red wire). I replaced fan motor, blade and capacitors 4 mos ago and all fine until now. If your fans are turning backwards air is being pulled through fans not coil.

I Know When I Bought The Motor They Gave Me The Wrong Capacitor.


Units with 2 condenser fans and only one running and this causing second one to run backwards. I’ve only seen it a couple times on condenser fan motors but it does happen.

Condenser Fan Running Backwards (Pulling In Air From Top And Out Coil Sides).


In general, the fan that moves air over the coils and around the compressor of the condensing unit should spin clockwise. Also, you should connect the new motor to run on low (red wire). The new motor you list requires a 10 mfd capacitor to run at 240 vac.

The Capacitor Has Been Changed.


Yep seen this happen on rtu's as well. I'm thinking about calling a priest instead of an a/c tech. I checked the values on the capacitors and they check out ok.

And probably has been since i first turned it out. Either one of them must be on the fan port and the other on the common port, along with one wire from the condenser. I replaced fan motor, blade and capacitors 4 mos ago and all fine until now.

This One Was An Interesting Call.


Install baffles for proper air flow and fan operation. Once it was running forward and i squirted water on the coils and when some water got on the fan blade it reversed right before my eyes. Your capacitor is too small.
