Can anyone tell me where I can find a diagram online for a Lennox M# CPH10-653-1Y?
I can not read the serial # on the tag.

It looks like a 5 ton rooftop heat pump.
This is the closest thing I have.

Thanks guys. TAC mine is older than the info you posted. The unit I am working on is a recip. compressor. The defrost circuit board has two sensors theat come off the bottom of the board, one with blue wires and one with red wires. Not sure if any of this helps.
