Troubleshooting GE X13-SERIES ECM2.3 Motors

TROUBLESHOOTING GE X13-SERIES ECM2.3™ MOTORS

NOTE: Bard Models PA13422, PA13482 & PA13602 contain the X13-Series Motors.

If the Motor is Running

1.It is normal for the motor to rock back and forth on start up. Do not replace the motor if this is the only problem identified.

2.If the system is excessively noisy, does not appear to change speeds in response to a demand (Heat, Cool, Other), or is having symptoms during the cycle such as tripping limit or freezing coil, check the following:

a.Wait for programmed delays to time out.

b.Ensure that the motors control inputs are wired to the factory supplied wiring diagram to insure motor is getting proper control signals and sequencing.

c.Remove the filter and check that all dampers, registers, and grilles are open and free flowing. If removing the filters corrects the problem, clean or replace with a less restrictive filter. Also check and clean the blower wheel or coil as necessary.

d.Check the external static pressure (total of both supply and return) to insure that you are within the ranges as listed on the unit serial plate. If higher than allowed, additional duct work is needed.

e. If the motor does not shut off at the end of the cycle, wait for any programmed delays to time out (no more than 90 seconds). Also make sure that there is no call for “Continuous Fan” on the "G" terminal.

f. If the above diagnostics do not solve the problem, confirm the voltage checks in the next section below, then continue with the “Model X13 Communication Diagnostics”.

If the Motor is Not Running

1.Check for proper high voltage and ground at the (L/L1) (G) (N/ L2) connections at the motor (see Figure 13). Correct any voltage issues before proceeding to the next step. The X13 Motor is voltage specific. Only the correct voltage should be applied to the proper motor. Input voltage within plus or minus 10% of the nominal 230 VAC is acceptable.

2.If the motor has proper high voltage and ground at the (L/L1)

(G)(N/L2) connections, then continue with the “Model X13 Communication Diagnostics”.
