Replacing Top Circuit Board
Before determining if top circuit board is bad, contact your nearest AP or Cumberland Service
Representative to aid in diagnosis.
To replace the top circuit board, begin by removing the “Incoming Power” and “Flex-Flo Motor” wires from
the left terminal block. Un-plug the “Auxiliary Switch” terminal block plugs on the right side of the top circuit
board. Unplug the “Toggle Switch” spade terminal wires from the top board. Remove the four (4) screws
(S-7393) that secure the top board to the bottom board.
IMPORTANT: The left end of the top circuit board is plugged into a socket on the bottom circuit board, so
you must wiggle the top circuit board back and forth, while applying upward pressure until
the board becomes free.
To attach a new top circuit board, reverse the procedure above. Be sure the plug on the left side of the
circuit board is aligned with the socket on the bottom board before pressing into place.
