## Description

Product description Supplying Demand HVAC W51 Motors Double Checking Your Information Always check your capacitor first. A bad capacitor can cause symptoms similar to a bad motor. If the capacitor is bad, it will send the wrong voltage to the motor. This can possibly cause it to overheat, not start, or run slowly. Match up the Voltage and Phase this way The number listed beside "PH" on the label should match the Phase on the motor. The Voltage is typically the same, as most HVAC units run on 208/230 Voltage. Tool information for HVAC Motors SD HVAC Motors are designed to be universal and flexible with your needs. Simply match up your Horse Power, Phase, Speed (RPM), and Voltage! These are amazing motors to keep on your truck or handy anywhere you store products. Can You Do It? Yes! But do it safely. Shut off power, disengage capacitors and make sure you're not going to get shocked. From there you need the tools and patience. Sometimes this can be plug-and-play, but in many cases, it may not be depending on your unit and needs. Check out our Motors and Motor Tools below!

Review: Works great right out of the box. - The only issue I had is that the OEM motor had a yellow lead where this one has a white one. Other than that, I just matched colors plugging in the new leads as I pulled the old ones. One other thing--the motor power leads (blue white black red) had no quick connects on the ends. If I hadn't had some in my toolbox, it would have meant a trip to a hardware store in the middle of the install. On the other hand, a 3/8 in 12-point socket fit the square shaft lock screw perfectly making it easier to install without having to use an adjustable wrench. So have three quick connects and a 3/8 inch socket, and it will go on much easier than it was to take off the old one.

Air Handler for HVAC. Works great

### ⭐⭐⭐⭐ Works great, just not 3/4 HP as advertised
*by G***. on July 13, 2022*

My blower motor blew out in the dead heat here in Houston, TX. Using Google I was able to isolate my problem to either the motor or capacitor so I purchased both. Capacitor replacement alone didn't fix it so the motor was up next. Temps inside the house got as high as 93 degrees upstairs in my dual zoned home. The motor arrived quickly and cooled the house down to a chill 75 in 95 degree weather. So in that sense it was perfect as it righted the household. I also noticed how quiet the motor ran as others mentioned. Now i've also discovered what others mentioned. It runs nice and quiet because the airflow is very low now. This may be rated as 3/4 HP but it is not. Thats why I took away a star. It works great for what it does, it just isn't nearly powerful enough to match the motor it replaced that had much better forced airflow through the registers. Unfortunately I'm beyond my return window so I will be putting this on the shelf and getting an actual 3/4 HP motor. I'll just keep this on standby in case I have a motor problem later down the line.
