NOTE:
You must use the correct replacement control motor module since they are factory programmed for specific operating modes. Even
though
they look alike, different modules
may have completely different functionality. The ECM variable speed motors are currently the
only motors that
can have the motor/control module replaced.
IMPORTANT NOTE:
Using the wrong motor/control module voids all product warranties and may produce unexpected results.
*MOISTURE CHECK: -
Connectors are oriented "down" (or as recommended by equipment manufacturer).
-
Arrange harnesses with "drip loop" under motor.
-
Is condensate drain plugged?
-
Check for low airflow (too much latent capacity).
-
Check for undercharged condition.
-
Check and plug leaks in return ducts, cabinet.
