Recommended Checks

Read the alarm from the blower drive (not the
general alarm in the Xe controller) and troubleshoot
according to the fault code/number found in Tech
Direct.

Is the blower drive incoming voltage balanced to
ground? If not, correct.

Disconnect motor leads from the blower drive
output. If the blower drive shows running, perform
Megger/Milliohm on the blower motor.

P3 Terminal connection is the one receiving the
drive status alarm. Check for good connections.

Ensure the ductwork of the machine is properly
sized not creating airflow restriction = high amps.
