OEM Condenser Motor, Fits Carrier, 1/4 HP 1100 RPM, 208-230V, # G3905 Motor Replaces Part #s HC39GE237A, 5KCP39EGY823S

Works great. Our system is over 30 years old and my husband occasionally replaces little parts here and there and our A/C is like an Arctic blast. Don't spend thousands of dollars to get a new system. Everything so far on our old Carrier has been replaceable with inexpensive parts and easy straightforward repair time.

Well built, heavier duty wires than OEM - maybe that is NEMA code changes over the years but they were definitely larger duty wires., connectors were nice and tight. The condenser was american standard brand. This is a carrier motor, I figured a motor is a motor. OEM had cast in threaded holes to hold to the fan guard. Had to drill new holes, its sheet metal so not hard, the motor case fasteners on the new motor here had plenty of length and design is for a flat mount, went in just fine. Used washers and loctite red to secure with new nuts (don't forget the loctite you newbies, secondary locking feature in a vibe environment is a fine practice). The shaft length of this motor is a little shorted than OEM but I set the fan set screw at the end of the shaft and it was just fine. Installed it all back together with no issues. Wire colors were different so I had the start cap wires reversed originally, no biggie, it just ran backwards, easy fix to swap terminals. All done and a cold beer later, its working like a champ. Motor looks to be well built and should outlast my ancient compressor. So for a hundred bucks and an hour, well worth it.

Just installed it but was an exact fit. Works great.

Needed to replace a dead fan motor (part number 5KCP39DGJ281S) on a 30+ year old ac condenser. The existing motor part number / exact specs are no longer available. At first I chose another "overseas" dirt cheap choice primarily because it was available next day and secondarily because it had a longer shaft which gave me more room for error in the fit up. Unsurprisingly, that motor didn't work! Wouldn't turn on and didn't have proper continuity with testing the leads, also worth mentioning it didn't have the proper drain holes and came with the motor studs assembled in the wrong orientation. This motor however, works! It fits great, the lead wires are the same thickness as my 30+ year old quality GE motor, it has a drain hole, came ready to go and fired right up! Not sure how long it will last, but for the price and the quality that I can see and feel, I'm quite happy!

Bolted right up. Hardest part was getting the fan itself off original motor.

First time replacing a condenser fan motor. Amazon saved me lots of money. It was very easy to replace and my old 1990,s heat pump is up and running again. The hardest part was getting the fan off the shaft. I used some kroil penetrating oil and made the job easier.

Like everyone else that buys this motor, my previous fan motor was making a loud squealing sound and it sounded like it was about to fail real soon. I looked up the part number and Amazon produced this result. It's an exact match. I watched a youtube video on how to install it. My only gripe is it said it would come with a capacitor, but it wasn't a big deal since the one they had picture wasn't quite the one I needed.I got everything installed and it ran perfectly the first time I turned it on. It's been a month since I've installed it, so it's humming right along.UPDATE: The motor has failed. I bought this in April 2022 and it failed late July 2025. I expected several years of use. This motor replaced my OEM fan on a Carrier that lasted 22 years! I'm still using the same AC unit and the only I had to replace so far was the fan, but I'm disappointed in the lack of longevity from this motor.

The installation was simple and the wires matched the old motor in length, color and connectors. I thought it was a capacitor issue but the fan was original and simply giving out. Take note of the placement of the old fan blades on the new motor and make sure everything has good clearance. The unit is quieter and so far so good - we are three days into it since the install. AC is working well.
