Trane Voyager Condenser Fan Problems

[ErikNeMechnical]

So i replaced a condenser fan motor capacitor and fan blade on a Voyager Rtu and when i fired it up the motor was spinning backwards, its a single phase motor, so i was alittle puzzled, i called Trane and they were alittle confused as well, suggested i swap the wires from the contactor and capacitor, motor was then spinning correctly but drawing about 1.5-2 amps higher than what it was rated for. So bottom line getting a new motor and capacitor from trane and trying it again. Just wondering if anyone has had anything similar to this?

Was it a 3 wire fan motor?

[supertek65]

If there are 2 fans
The second one can start backwards.

Ive seen it.

Ive seen it.

What is the Model Number of the RTU?

[ErikNeMechnical]

There is 2 compressors, and 1 condenser fan, the mod number was YCD120C4L0AB....and it was 3 wire motor Trane suggested swapping the black wire on the contactor with the purple wire off the cap and it seemed to correct the problem other than the high amp draw and the door was on the unit lol.

Double check the motor, cap and blade, just cause they're new, doesn't mean they're the correct ones, Trane makes mistakes too. Got a 208v compressor in a 460v box before. Didn't run very long.

Sounds like the motor is bad. I'm not sure if you replaced the motor, capacitor and blade or just the motor capacitor and blade. If it was a new motor, you got a bad one. I have purchased several motors from Trane that were bad out of the box or only lasted a day or two.

Exactly what I thought and why I asked, I myself have done it more than once(we have a ton of Trane Voyagers around here) and that is the proper fix.

Now on the high amp draw is the capacitor the same size? When you changed the fan blade did you put it in the same place?

[ErikNeMechnical]

Yeah fan blade is in same place capacitor is good, just swapped the motor and cap with another new one and its working great now... Weird **** but atleast I don't feel to bad now that some of you guys have experienced this.

Wound for opposite rotation. Factory mix up. It happens.

What he said is true, had this happen to me before, got another new motor and magically it ran the right direction.

Carrier 38AKS condensing units with 2 fans do this too. #2 fan rotates backwards while #1 runs, when #2 is energized, it continues to run in wrong direction. A new capacitor fixes this.....for a while!

Have to be careful with York Equipment they run condenser fans in reverse to maintain system head pressures.......usually 3phase equipment though....

I have not seen that before, interesting. Must have a second contactor to run fan in opposite direction.

maybe at the factory they put the rotor in the wrong way. could have tried flipping the rotor.

Now that's one I haven't run across. Do you have a model number on that?

[Birmingham]

i have had the trane motor run in reverse before, i flipped the fan blade to get them by untill the new motor arrived. not the best. high head, also had to run a sprinkler on the coil. great for roof leaks.
