4200740 Fan Motor Kit for Sub-Zero Refrigerator

The motor shaft is shorter than in the original, so I wasn't able to use the original plastic fan. I used the metal fan included in the kit, but it was loud. I uninstalled and reinstalled. The second time I noticed the asymmetry of the blades and the "motor side" note on the original fan. The steeply angled side of the blades should be closer to the motor and the flatter side of the blades should be farther from the motor. With the fan installed that way, the noise is gone. (We can still hear the fan, but it is comparable to the original.)

Works perfectly in our 20 year old Sub Zero 650. Hard to tell if it’s any louder given our old one was likely falling for some time. Great price versus the $1k I was looking at for service call and parts from Sub Zero.

OE Supco motor. Fan fits perfect

Works well, but it is NOT made in USA. It is made in China. Dissapointing.

Supplied unit is a good replacement for the OEM fan motor. I did not have luck swapping the OEM fan blades for the supplied ones, as others recommended, but I also did not have a fit issue. Plus, I purchased the unit used with a broken fan, so I do not know what the original would have sounded like in a comparable setup. It's certainly a lot quieter than the broken fan was! This replacement seems absolutely fine in terms of sound level. Yes, you can hear when the fan turns on. You also have a space-ship fridge in your kitchen, so hearing it sometimes seems within the range of normal. You will need a quarter-inch SAE socket to get the old bolts out. Also note that this kit did not supply the same quick connect connectors that Sub-Zero uses (as another reviewer showed receiving in 2021), so to get it up and running I had to cut off the old one from the fan and wire this into that, then clip it in. It works, but I'm not a fan of having the extra connection, so I'm on the hunt for a proper connection.

My 22 yr old Sub Zero 650 S showed a temperature of 59 degrees after returning from a trip. I took down the grate and noticed the fan wasn't turning. I gave it a spin and it would lethargically spin, and keep spinning but never start again it the condenser toggled it off. I called my long time Sub Zero repair outfit and they could come for 9 days. I left a table top fan on a ladder sitting infront of the refrigerator and kept everything cool. My wife didn't really find that too convenient and today is our 27 wedding anniversary, so I have experience knowing what I had to do. 9 days wasn't going to cut it.I ordered this kit it, it came in 36 hours and I preceeded to swap out the motor. It has a great replacement of all the hardware, a new fan, wire nuts, plastic and ceramic, ground wires, and rubber gaskets.Unlike other reviewers issues, the new oversized fan fits in the 650 shroud with no problem. I put it all together and all was super cool. Like others, I did find it a bit louder than before, so I popped it back out and reattached the old fan. The noise volume lowered to a completely satisfactory level.I am surprised that the fan pulls air across the radiator and into the condensor box instead of blowing out across the radiator fins for maximum cooling. Is that what everyone else is getting?I am pleasantly going to call and cancel what would have been a 500.00 repair here in Los Angeles.I appreciate the kit, fast ship, and forum reveiew that help make these jobs easier.It's "all cool" with the wife. Pushing on for another 25 years.

Works perfectly.

Ordered this because it listed the manufacturer as Sub Zero, instead of those similar cheaper condenser motors on Amazon. The motor is manufactured in China. OEM for Sub Zero was made in Indiana. You need to cut off the OEM plug from the old motor and transfer it with wire nuts to the new motor. It's a little bit louder than the OEM motor. Save your money and buy the cheaper motor.
