TROUBLESHOOTING GE X13-SERIES ECM2.3™ MOTORS CONT’D.

Model X13 Communication Diagnostics

The X13 motor is communicated through 24 VAC low voltage (Thermostat Control Circuit Wiring).

1.Start with unit wiring diagram to confirm proper connections and voltage (see Figure 14).

2.Initiate a demand from the thermostat and check the voltage between the common and the appropriate motor terminal (1-5). ("G" input is typically on terminal #1, but refer to wiring diagram!)

a.If the low voltage communication is not present, check the demand from the thermostat. Also check the output terminal and wire(s) from the terminal strip or control relay(s) to the motor.

b.If the motor has proper high voltage as identified above (Motor not Running #1), and proper low voltage to a programmed terminal, and is not operating, the motor is failed, and will require replacement.
