Hello. long story short, my capacitor went out on my ac condencer fan. I replaced the motor and capacitor (with the same spec motor). Turned it on and fan spins wrong way. Am i crazy?
single phase motor
3 uf35 capacitor

thanks in advance. i am at wits end with this ac, heatpump unit.

and i tried the search.

You have the wires mixed up on the capacitor. Carefully follow the wiring diagram on the unit to sort it out. Some fan motors have a plug you can use to change the rotation but it sounds like the wiring is mixed up on yours.
That worked. Thanks for your help. :thumbup: i walked past that wiring diagram probably 300 times and never thought to check that. :censored: .

Hey Yuri, you get your DIY check to day?

I got a five percent raise!:laughing:
Just hit 1000 posts today so I deserve one. Get paid tomorrow from my real job, hopefully the raise is there instead.:thumbsup:
Was it measuring voltage?
Why did it wait so long to blow up (but see below)?
Will this be a warranty repair?

This film is way speeded up; it should have take 1/4 sec. for those test leads to fall back down.

That video is why I hate Fluke. That thing blew on 460v 3~.

Good thing I was wearing protective gear.
Wouldn’t that be a single phase 460 disconnect? It only has 2 wires not 3.
The device the meter was connected to was a meter base. All meter bases feed from the top, the load is on the bottom. This one was set up as a test.

Very likely that was 480 volts. 208 or 240 will make a nice POP, but 480 is much more spectacular.

Either way, once you see what can happen, you'll likely check your meter a bit more carefully.

That was just a gag post. Not real.
