My 10+ year old AC fan stopped working even after I replaced the capacitor. So the next suspect is the motor. I called my AC guy but he wanted to charge me almost $500 to come and put in an aftermarket motor. But when I saw this MARS motor, I decided to give it a try. The MARS motor is similar in specs to my old fan motor just slightly less than the 1110 RPM in mine. The bolts that stick out of the new motor are a bit long. So I decided to use a hack saw on them and snack them off. My old motor has 3 wires vs the 4 wires that came with the MARS motor. I did not use the brown stripe wire in my dual capacitor configuration. I also measured the distance from the back of the old motor to the point where the fan blades attach to the motor shaft. This gave me an idea where to attach my old fan to the new motor. Also, my fan hangs upside down in my AC unit and I had to change the wiring to have air blow out of the AC unit. These are the short colored wiring that sticks out of the motor. Once I hooked up the motor to my dual capacitor and contactor, it fired up the first time. So I saved over $400 dollars vs letting my AC guy change the motor. If you are a DIY'er and likes to tinkle with electronics as I do, this is an easy project. One final tip - pull the rubber plug out on the bottom of the motor to let condensation moisture out. If you do not do it, the moisture will damage the motor over time.
Arrived on time, easy installation, the a/c is back to be working. Came without terminal plugs, However, Black to power source(Contactor), and, on Capacitor side, Yellow to 'C', and Brown to 'Fan'. Unless uses separate Capacitor (5uf), the Brown/White wire will not be used.
This motor is nice. Greater quality than the OEM motor that was in the unit. Very happy.

It took me longer to figure out how to wire it up than to install the motor....
Yellow: hooks to main contactor relay
Black: hooks to black common twist cap along with the other black common wires.
Brown: hooks to startup capacitor terminal marked FAN
Brown/White: hooks to startup capacitor marked C
Mine has a Dual Startup capacitor so I hooked the Brown to the terminal marked FAN and the Brown/White is not used in this case, so I cut off and sealed the end because it is not used for a Dual Capacitor.

So I saved about $100.00 compared to a new OEM unit. And got a better unit out of the deal. Unit started up immediately and ran strong and smoothly. I mean I could even tell the superior quality by the tone of the unit as it ran.

Oh yeah, I have been ordering regularly from Amazon for over 6 years and this is the very first product review that I have written, I would highly recommend this unit.
Replace my 15 year old AC fan motor. It kept stop running after 30 minutes of run time. Replaced the capacitor but the problem persisted. Next logical step is the motor itself. It would have cost me a tone of money had I called the A/C repair guy. (The last service guy from a well known local service company told me that I need a brand new unit for $3 grand and he can knock it down by $500 if I let him have it. I had different honest guy came to look and turn out to be just a simple dirty coil). The motor is bi-directional and it came with clockwise setting. My fan motor is hang up side down so I have to reverse the flow direction in order to get the correct air flow. Air should be blowing upward, not down. It's an easy task, just follow the instruction to connect the color wires for flow direction setting. Wiring diagram is clearly listed and simple. The mounting bolts are way too long so I have to cut them with a bolt cutter to prevent the fan blades from hitting them. It does not come with wire terminals so you have to buy them separate at the local hardware store or HomeDepot. AC is back running.
Worked perfectly for my a/c . Nice and quiet now. Cutting the fan blade post was a bit of a drag, other than that I highly recommend. Wiring diagram was on the outside of the box, NO instructions inside. Still super easy to figure out and replace. Videos galore on the internet to show you how to do it if you are a dyi type of person.

My hubby had no probs replacing this part on our AC. We bought this part a few years ago without hassle as well but living in the desert, we use our AC 24/7 so 3-4 years of use on a unit we run everyday is a decent value for our money.
Bought this as the specs showed it compatible with my unit. The exact match for my fan motor was double the price of this, but you do have to do a little work to get it to fit and wire up properly. As other comments have noted, you need to cut the fan shaft as well as the bolt threads to match that of your old motor. Then you need to wire it up properly (3 or 4 wire) as well as make sure it is blowing in the correct direction. If you have some common sense this is not a big deal.
Works better than the original!
This motor was easy to install and fit correctly to the fan mount and the fan blade. My application required a direction change which was easy with the provided connectors. Had to look up what to do with the Brown/White wire in a combined capacitor application but wasn't a problem after I found to just leave it unconnected / taped up. Wires were of ample length.
