NOTE:
To make it easier to remove and install the new PCB it is recommended that you dismount the contactor
leaving all wires attached and pull it out away from the PCB. This will give more room to maneuver
the PCB.
If you are working on a CE unit with a CE filter to the right of the contactor then you will need to remove
the filter to access a mounting screw on the PCB.
6. Remove the (15) screws from the Capacitor PCB. Set the screws aside for reattachment later.
NOTE:
There are two screws that are different from the rest. These screws must be used in the same HS5 and
HS6 locations when reassembling.
