Stuck on Condenser Fan!

Last summer AC worked fine. No issues. Winter, Heater worked fine. No issues

Go to turn on AC. Nothing. No compressor, nothing. Reset breaker wait a few minutes, try again.. Compressor turns on for a few minutes ( a little louder and more ticking and vibrating then usual i think) but no condenser fan.

Go up, looks like the old condenser fan burned up, chard on the inside, rain slinger(cap) all melted. DONE.



So sense then i have replaced the Fan motor

The run capacitor and the Dual run capacitor just to be on the safe.


My problem is, my condenser fan is still not turning on. I wired it back exactly the way it was in regards to connections to the capacitors.

the new Fan Motor one came with a Black, Purple, Brown and Brown/white

The original motor came with Black, Yellow, Brown and Red. (the red was just hanging in there with a wire nut on the end)

I connected motor:

Black to Black
Purple to Yellow
Brown to Run Cap
Brown/White to Run Cap

See Below

The Black does not go to the contractor (see start in bottom right end in top left)
Yellow goes to C on Dual Run CAP

This is how the previous motor was wired. so i just did the same




My issue is that the Condenser fan is still not starting. If i turn on the thermostat or push down the contractor, the compressor turns on, (seems to be inconsistent in its vibrating and volume though) but still turns on and runs for a few minutes before shutting off.

Any ideas?

I have been told that i can just connect the Black and purple form the motor directly to the Contactor, but im not sure which terminals to connect too.

I also have heard that the Contactor might be bad. but if it was, wouldn't the compressor not turn on?

Any ideas. I have tried to test Voltage on contactor but im doing something wrong im pretty sure. Could i get a walk through on that based on the picture below?

what i think you are talking about is actually a silicon or some sort. So i dont know if that means that it is melted or not. But if i just spend the 30 dollars to replace that should it also fix any voltage problems that i may be having?

and does anyone know if this is why the condenser fan would not be starting?

i do have an Analog multimeter, But i have used it mostly for checking outlets and ruining sprinkler value wires so im an amature with it i guess. I read as much as possible before hand i want to make sure i testing the right terminals for the right voltage
