Rated 5 out of 5 by 2reviewers.
Rated 5 out of 5 by Nice motor. Purchased to Replace failing Carrier OEM. Simple install. Beefier than original (larger motor casing, longer shaft, etc.), no problem; trim-to-fit. Stingy, Draws ~ 4.0 amps on medium. Have to watch directionality, can change the rotation by polarity index built-into harness. February 13, 2013
Rated 5 out of 5 I used this motor to replace an A.O. Smith motor (Item # 4MA66) that was noisy beyond compare, and many times failed to start on the lowest speed. It's so quiet my wife can't tell when it's running! October 28, 2012

Further, can you recommend a 1/4" quick connect terminal block I can use to hook the motor to power. Note the 2MDV6 capacitor has 1/4" connects.

one of the questions on the page for this item is:
What is the wiring for a 3 wire furnace. Do you need to connect a capacitor?
Grainger's answer was:
Grainger Employee

I will email you a copy of the wiring diagram and that has information on 3 wire wiring.

I, too, would like a copy of the wiring diagram for this product (can't understand why neither the OEM specification sheet and the OEM Wiring diagram are not posted on the site.
