Let’s Fix It! | Dead Daikin AC Condenser Fan Motor

I really enjoy making these talking videos for some reason, so for this occasion, I'm taking you through the steps I took to fix my neighbor's AC condenser fan motor that recently died on him, and also the kind of 'shopping district' I go to where I can reliably source random odd/old stuff!

I honestly don't get why manufacturers nowadays have switched from stamped steel motor shell type motors to these cast resin motors that are practically unrepairable. On older style stamped steel motors, the windings can still be rewound if for some reason the motor decides to quit, whereas these resin-packed motors are meant to be thrown away when they die because scrappers won't have an easy time getting the metal parts out, as the man who opened this motor for me pointed out.

Also an interesting thing I only realized later was the temporary motor put into this AC unit is for a smaller capacity AC with a smaller diameter fan blade that spins clockwise at a higher RPM than this black Daikin blade. It was RED HOT when I started tearing the unit apart to replace the motor since that motor was not only reversed from its normal operation, it's also given a larger fan blade with deep pitch & a higher capacitor value. That might explain why the fan blade was stuck on it good, even though the shaft isn't rusty. The motor I bought for this unit was from a National unit with 5 wing deep pitch blades of similar diameter to this Daikin's blade, so it should run just fine.
