Super fast Shipping. This replaced an original 3/4 HP ECM 2.3 Motor. The original motor was still working and tested fine but the original controller was bad. (Typical of these where everything worked but motor would not shut off after thermostat quit calling for heat or cool)
New motor fit easily into the existing belly band mount. (Just make sure it's not skewed so the squirrel cage is not crooked in the assembly)
The motor for now seems to have the same power as the original even though it is a little shorter in length. Time will tell how long it lasts but confidence is high provided the controller interface is set up to stay within or close to the air handler specs regarding static pressure and temp rise. It does come with a two year warranty.
The controller interface is the Gen 2 model and was pretty much plug and play aside from wiring it to the thermostat control which has many options for one and two stage heating, cooling or heat pump. The instructions were very clear and straightforward for all of the options.
The controller interface can mount by the blower assembly or in the same area as the furnace controller. Since I had the room I mounted mine next to the furnace controller.
The original Gen 1 interface had the setup options for changing speed, rotation, time delays, rotation etc, on the face of the panel with a screen. The Gen 2 model has two buttons to change speed by 5% higher or lower and all other settings are now done through WiFi and a phone or pad app. The WiFi is proprietary and therefore connects as a standalone without connecting to "your" network.
My only gripe is the WiFi signal is bit weak, probably so nobody can take control of your air handler settings without being almost right next to it.
Problem is, it is so weak, that I have to pull the metal cover off the furnace to get it to connect. Really not a huge problem because once its set for heat and cool settings you probably won't ever have to do it again unless you reset it to factory defaults. Hence the 4 star rating.
Aside from that, it is probably the easiest and most cost effective way to replace any issues (motor or control) with the ECM 2.0 or 2.3 that use a 16-pin connector plug on the motor.
It is currently wired for single stage operation even though the furnace is a 2 stage so I can't comment on functionality on Stage 1 or (low fire) but it is suppose to run 30% lower then the 2nd stage (high fire) settings on both the gas valve and motor speed. The furnace was originally installed on a old mercury round thermostat so the 2-stage option was never hooked up.
I intend to wire this for 2-stage operation since I now have a thermostat to run it that way, and can comment on that at a later time.
For now, everything is running perfectly!
