We recommend replacing the run capacitor, a
weak or damaged capacitor can cause damage to the motor or unit.
When replacing the electric motor, the run capacitor value may be different than
the old original motor,
which is okay, you will just need to change the capacitor. Below are tips and
views that you may see and how to select a new capacitor.
*PLEASE DISCHARGE THE CAPACITOR BEFORE
HANDLING*
We always recommend a certified trained technician to
help with installation. Always turn off the power before attempting to replace
any electrical product.
Most A/C units have a dual rated capacitor;
half of the capacitor works the compressor pump and the other
half works the fan motor. They will be labeled as follows on the capacitor:
C = Common = Incoming Voltage - 4 male prongs
Herm = Compressor - 3 male prongs
Fan = Fan Motor - 2 male prongs
Below is just an example of how to select the capacitor based
on the new motor and herm rating for the A/C
unit. Please read fully, and the photos are just examples and should not assume
your ratings are the same as the example.
The higher MFD or UF rating is the compressor, the lower is the fan motor.
In the example photo below, 25+5
Look at the rating for the new motor, it will
be listed on the label of the new motor, take note of this rating.
Then look at the old capacitor, take note of both ratings.
Then select your new capacitor based the new motor and old herm rating.
Motor label on the right, circled in red is the capacitor rating, 5mfd/370volts
For
Example, if your new motor is rated for a 5mfd/370VAC capacitor, and your old herm number is*There will times when the old motor ratings will match the new motor, we still recommend replacing the capacitor.*
