Due to the nature of power factor correction and other sizing criteria it is best to open the can on the motor that protects the capacitor and order a comparable unit for capacitance, number of sections (- ie, start/run versus Start or Run) plus capacity and working volts AC. Unless ordering from the original compressor supply company, most parts houses will not have a cross reference with that data.

Does it make a difference if my spa replacement motor only has one hump not sure what it's for and the original I'm replacing has two humps?

Under the hump, is a capacitor. So that two hump is a motor that has two capacitors. I would suggest getting a like replacement.

5 BHP
4 HP
Same Difference... It's a game the pump manufacturers play to fool the consumer.

Emerson 1/2 and 1/6 HP 115V Adobe Air Part # 112366A in 6year old Master Cool II Evaporative cooler blower motor runs OK with belt disconnected but not enough starting torque to spin blower.

If your motor has a seperate start capacitor it may need replaced. Have you tried to spin blower by hand when it should be on to see if the motor has enough power to keep it going on its own. If it does then it probably is the capacitor. Some motors have the capacitor built into the motor. If yours does then you will need to replace the motor. Before I did this I would give the blower a real good cleaning. Brush off the blades with fine wire brush and blow everthing out with compressed air. Clean and oil motor if it has any oil ports on it.Best of luck and thank you.

I'm looking to buy motor for an Airco Gas furnace model ACF-45, serial #DI-109. The motor is Tamper, 1/6hp, 1727rmp, type S-100336. Do you have any suggestion?

Hi, W/D here.
Make the necessary sketches, showing what color wire goes to which terminal (trust me on this, it's a really good idea). I do it whenever two or more wires are involved, and I've been known to also lable terminals with the wire color with a "Sharpie". Remove the motor and start capacitor. Take both with you to your local appliance parts supply house. They will match you up with a similar motor, and match the capacitor to the new motor. Getting the exact motor you described isn't important. Getting a good quality replacement motor with your horsepower rating, shaft size and matched capacitor is. They'll have it, and the cost will be less than running one down. I installed a replacement in a furnace last week, with the motor, capacitor and a pack of crimp-on terminals (I ran out!) costing about $109.00. Your's may be less at 1/6 hp. The one I installed was 1/3 hp, replaced a GE, and works fine.
Best regards, --W/D--

I need to replace the capacitor for a flowmaster xp2e 230v model 05825001-2. old one says 35UF +/- 6% 370VAC. is this a run capacitor? i have found replacement capacitors online that say (35) 370VAC, is...

Yes, that is a run capacitor. You will also need to clarify oval or round design.

You should take the old one in to a local electric motor repair shop if it is not obvious it is blown. Even if it is, their will be other issues that caused the capacitor to fail in the first place. You will want to try to identify those and fix them as well or you will be replacing the capacitor again soon.
