Condenser Unit Shaking/ Vibrating? Here's Why! Easy Fix! 

thank you, showing the condenser working WITH the problem really help diagnosis my unit very thoughtful

Short, sweet and to the point. Very informational thank you.

Great vid right to the point and I appreciate you providing the three reasons why the vibration could be happening...mine was the last reason and will get it fixed now...thank you!

Superb info! Thank you very much for taking the time to share it with us!

Very helpful, crescent wrench worked best for me to remove the screw lock on the fan motor to removed the blade. Before I was using plyers because it was all I had. Definitely worth the 6 bucks to go to Walmart and get a small crescent wrench, now I got to replace my fan blade because it got tweaked ever so slightly and its vibrating.

This is probably my issue I removed the fan to clean the coils. Thanks for the video

The one person who gave this a thumbs down must be the technician who destroyed the original fan blade

Thanks bud solved my problem. That fan blade had it coming way it was stuck. New one did the trick.

Thank you SO much. My daughter's AC looked like it was gonna fly off the foundation. We just had an ice storm, so yeah, pretty sure that's why.

Thank you.

Big time !! Thank You !!!

What would cause a fan blade to have a hair line crack in one of the blades, I noticed that in one of the blades when I was cleaning my unit and there was no noise before but after the cleaning there was, that's how I found the hair line crack. I ended up using the aluminum welding rods to hold it for now but currently looking up the correct fan blade for my condenser.

Over tightening those 4 screws is a thought. I installed an universal motor and my unit started vibrating. I played around and set the right height on the fan and it stopped vibrating but 3 days later is making awful whoop whoop noise. I didn't use original brass nuts. I think I'll take motor off and cut those extended threads to the same length as original and use the original brass nuts. I don't think I tweaked a fan on the fan blade but I might have. There's two little clips on fan blade that look like they are for balance. Maybe there were three and one came off. Lastly I'll run it without fan blade. This is getting tiresome because I keep calling off work to deal with it. This is the third time I called off in two weeks. I just can't afford catastrophe damage to condenser or unit.

Very nice video very helpful although I would ask, could you instruct how to replace the fan blade that would even even make this video even much more perfect but very informed thank you very much

Thanks

Did you cut the shaft on the motor or did you leave it hanging real low. Some guys leave the shaft real low and that caused a lot of occultation.

How do you buy the right fan blade?bore size, 3 blades, etc does pitch matter?

I live in apartment with the AC vibrates the building what can I legally do cuz the manager doesn't seem to want to fix anything

I had the same problem. When I checked the fan motor it had all loose bolts and nuts. I screwed them and problem was resolved. However I was wondering why this happened... I suspect it was because I closed some ducts and the new air flow caused some kind of unbalance or resonance that impacted the fan motor. Is that possible?

Can ya just get the make and model number off the unit to get the right blade ? I was hoping to use the old blade til I got the new blade

Could a Failing bearing be a cause as well?

When this outdoor unit turns on it’s shake

So bending a fan blade will throw it out of balance? That doesn’t make sense.

Is it dangerous to use an AC with a fan blade like this?

Id try to bend it back if it was my house, if it's a customer it's getting replaced. I've bent stuff back before and sometimes a few months later it tweaks again and you have to go back. If it was my house I'd try it bc if it doesn't work i can fix it again no problem

I replaced my York condenser fan motor. Looked pretty simple. It was. AC company wanted $725 to do it. Now here's the problem it vibrates. I've played with it trying to figure out why. I used a universal motor. I called Johnston using company discount. I told them my AC model # and I got motor and capacitor. The only thing I can think of is there's something wrong with the fan blade. It's not cracked. I got it to stop vibrating last Friday but noticed it was making an awful whoop whoop sound today. I wonder if I remove the fan blade and see how it sounds without it? I was also wondering if I should just find an OEM motor instead? All the info from guys at HVAC shop guys at work say they use universal motors. The rpm is 1075 instead of 1090 but even the guys at Johnston say it's no issue. Any thoughts on this?

What should be the distance between the fan blades and the motor?

Hp difference shouldn't cause a problem as long as rpm is same

What's funny about my groaning Goodman condenser fan motor I bought a new one and same noise rumbling crap when I give it a shot of water from the house it quites right down motor runs at 103 degrees so idk what heck is wrong

This video did not show me how to replace the fan blades, maybe got edited out, gotta be carefull with these videos some don't show all danger's

Is it ok to still use it if it’s in this state? Our ac unit is doing something similar

Hey I'm watching this video because when I was replacing my fan motor I over tightened the bolts on the top just as you described but as I was doing it, I heard an audible "click" and now they're loose as hell. Now when I turn them with a wrench, it doesn't seem to have any impact on the tightness. Any idea why and how I can fix it? - sorry I'm very new to this

Looks like mine! These repair mans are bunch of idiots! Just ordered new fan blade!

Why are the butt connectors outside? Just curious

We just had a snow storm and my condenser blades froze up. When I started the unit it shakes violently. Is it because of the ice on the blades??

Very simple question, can the blades be installed upside down, causing issues?

Reverse rotation bro!!!!! CCW
