Upon diagnosis found unit to be in a code failure to calibrate pressure switch properly, upon further diagnostics placed manometers on negative side of pressure switch and positive side to determined that inducer motor was not the primary issue and it’s not, the inducer motor is pulling the proper WC” to close the switch, after cleared the air hoses to switch the furnace managed to calibrate and initiate cal for heat, furthermore I found intake piping clogged up with leaves and such. This will cause improper system operation if proper combustion air is not delivered.
