Upstairs Furnace

I replaced the blower in the American Standard furnace with a Grainger blower assembly to get more CFM.

Wiring:

  • L1 Common = White

L2 can be connected to one of the following:

  • Black High
  • Yellow Medium
  • Orange Medium Low
  • Red Low

On the controller board inside the furnace I have the Cool terminal hooked to Black and the Heat terminal hooked to Yellow.

Cap wires:

  • Brown-White
  • Brown

The motor has the following Dayton Model number: 3LU83J
Motor run capacitor is 7.5 Uf @ 370V
The blower has a Dayton part number of 4C591B
