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 10). 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”.
