I have a trane ac unit the module went bad and i have an ac repair man trying to sell me a used unit. my question is id the d3431214p34 or the mot09262 dont match does it matter. He said just the hp volts amps and rotation. i know nothing about ac work but i looked stuff up and from what i gathered the motor must match the module
Module must match the unit. They are programmed for the unit they are to be installed in.
used parts means walk away.

I could miss understand you and you may want to replace the bad module which is what goes out the vast majority of the time in which case you need the one for that exact unit/moto as they are programmed specifically. There are computer programs that people can use to change or modify a good module but they need the accessory and access to manufacturers database which some do not give out.
