This works, though I'd point out that it's a fix for motors with sleeve bearings (aka bushings) with oil-soaked wicking/packing material, as opposed to motors with sealed ball bearings. Back in 2016 I did *exactly* what is shown here when I noticed the OEM condenser fan motor squealing; it was about 8 years after the HVAC system had been installed. Since then, it's been another 7 years and I haven't heard the noise return, but today I went out and re-oiled it anyway. 15 years on one motor is pretty good, but I'm hoping I squeeze a little more life out of it!
Motors like this can last 20 years or more, but if you've had problems with it already I recommend buying a new motor when you can. I've had 2 fan motor failures- one was late at night when it was very hot outside, the other was late on a Saturday afternoon when service companies could not get to it.
Appreciate this video sir, been havin' AC issues during this heat and this helped when nothing else would. Family doesn't get a lot of income so something like callin' in someone to repair it was sort of a last option. Have a good one.
It's not possible for oil to reach the bearings on the opposite side of the motor because the rotor on the shaft will block it. You have to apply the oil on the other side.
I've got a 35-year-old Rheem AC unit that came with my house. It started squealing yesterday so I'm going to try this tomorrow. Still has cold AC for now at least, and the squealing stops after it warms up a bit.
My AC makes very loud noises in startup only lasting 10-15 seconds. It’s about 25 years old, uncertain if needs oil or not. For your unit did you isolate the fan as the issue based on the type of noise and how long it lasted?
If you took that motor apart and looked at what is inside you will see that you can't put oil on the top bearing and get it into the bottom bearing. You would have to almost fill that motor with oil before it goes past the armature to reach the bottom bearing. However in my case it was the bearing closest to the fan that failed, the other bearing was perfectly good.
Both of my 1993 Amana units are still going strong. One has the original fan motor! Just a little oil, cleaning and maintenance. Yes, new units are more efficient but if they have to be replaced every 10 years you lose ALL of that energy savings savings! Here's a vid of how just a few drops of oil keeps my unit going and going and going.... ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-wSBr0PDCbzE.html
