OK, for the right person this is a pretty simple question.
I have a Trane 4TEC3F36S1000AA 240v air handler motor. Not sure how to hook it up directly to power.
From the quick connect the black wire runs next to the General Purpose Relay ( DPDT PILOT 3amp, POWER 12 amp) into the rear whitish crimp connector, then up into the capacitor, then the yellow and black into the motor.
From the quick connect, the red wire runs to the upper left corner of the GP Relay, then a small red wire comes off the lower left corner of the GP Relay into the front whitish crimp connector, then to the big red wire with the terminal connector that is no longer connected but fits onto the plastic block on the motor that is marked A-B-C.
The way I think I read the wiring diagram is that black feeds directly from power into the capacitor and then black and yellow to the motor. Red feeds directly from power and connected to A for Low Speed, B for Medium and C for High Speed. Don’t see a place that a white wire gets hooked up for neutral.
If that is correct, this would mean I don’t need the General Purpose Relay (I assume one of the input wires is from the controller) and don’t need the Transformer ( 40va, 200/230v pri, 24v sec) which I’ll guess was used to power the condensate pump.
What say ye gurus of these things?
Thanks.
