Condensor motor confirmation
Hey guys, just wanted to get your opinion on condensor motor I'm putting in. I could not read the motor but had model and serial numbers. My distributor says old one was 1120rpm 1/4hp 230v. They said it was obsolete but gave me 1075rpm 1/3hp 230v and said that was the replacement. I installed it and it gave me a screeching sound so I pulled the disconnect and decided to Google the model number to see what Google would show. Google is showing me 850rpm 1/4hp and 230v. Hoping someone can help me confirm what condensor motor I need because I dont think the one I have is correct.
Model number - BATH-F030ab
Serial number - NFBM036049

The last part # I see for this motor is: S1-32425801002. This is a 1120 RPM motor and not an 850 RPM motor.
Johnstone Supply crosses this to a S1-FHM3728. This shows as a 1075 RPM, 1/4 HP, 208/230, Reversible motor.
You might look for it under the S1-FHM3728 number and see if you can come up with one.
The Luxaire BATH series is the same as the York B1PH series. If you want the installation manual and wiring diagram, email me.

Thanks for the reply! Sounds like the motor they gave me is pretty close then. The only difference is the 1/3hp but that shouldnt have given me the screeching sound. The only other thing I could think of that would cause that sound is the wrong mfd on the cap..

Amperage
Voltage
The Cap wont give it a screeching sound!

If it was a century motor I wouldn't be surprised if it was a defective bearing. I have had several in the last year. I avoid century when I can.

I'm tired of these mediocre "semi flammable" refrigerants. If we're going to do it let's do it right.
Unless we change direction we are likely to end up where we are going.

this if the blade is not messed up only thing i can think of would be a bum motor

check the blade hub, if its not a tight fit, it will screech pretty bad, one other thing I have ran into, the slinger on the shaft can rub and cause a loud noise, otherwise, it will be a bad bearing in the motor. I've had the same luck with century the last two years, but we seem to only get those around here and the bearing wont last more than a year or two.

I mostly use us motors rescue ex wire motors. They are very good. I have never had one fail. I have eaven taken one out of a condenser that was being scraped and reused it another time.

Thanks! The motor shuts off after about 5 minutes but still has voltage. Could it be shutting off due to high amperage?

Does that show the amps? The motor they gave me shows 2.4amps

The manual (B1HP) shows the condenser fan motor at 1.5 amps.
The S1-FHM3728 motor is rated at 2.2 amps.
The FASCO motor facts (page 34) states: Matching ampere rating is usually more accurate than matching horsepower.
It also states (page 33): An acceptable replacement for a 1.5 amp motor is between one where the amps are between 1.5 - 1.87 amps.
Put an email address in your profile, or send me an email (address is in my profile), and I will get these two pdf's off to you.

What was the amperage?
-
Thank you! I'll send you my email. Yeah this new motor shuts off after a few minutes and the amps on it is 2.4.

And rated 2.2
Houston we have a problem.
Factory blade?

Yeah a new fan blade was added 😤

Probably more pitch!

The new blade looks exactly the same as old one but I'll get a guage to measure the pitch. So it being a 2.4 amp motor and it originally needed a 1.5 amp would not cause the motor to shut off after a few minutes? I appreciate the reply!

I would not think so.
What amperage is this new 2.4 amp motor pulling while it is running? If it draws 1.7 amps it is too strong, and if it draws 2.7 amps, it is too weak.
A 2.4 amp motor should be operating in the range of 1.8 - 2.64 amps (per Fasco Motor facts).
