If the motor is not operating…
Troubleshooting the premium ECM motor can be very simple if you remember that it
is not just on or off. There are basically four problems that will not allow the motor to
run.
- There is no input power to the motor controller (high voltage inputs).
- There is improper or no communication to the motor controller (low voltage
inputs). This problem could be in the interface board or the low voltage
connector.
- The motor controller has failed.
- The motor module (3Ø motor) has failed.
Of these four problems, we can help you with three, leaving only the communication
from the OEM’s interface board for troubleshooting using the OEM’s service guide.
40% of GE ECM™ field returns are
“No Problem Found”.
Do not simply assume the motor has failed because it is not running!
