NuTone S10941420 Circuit Board PP Series
The S10941420 circuit board is a replacement for all PP series central vacuum units. Replacing a circuit board is straightforward. The board is held to the wall of the canister with two nuts that unscrew from the outside. Once these are removed, pull the board away from the side wall. One by one, remove wires from the old board and reinstall on the new board. Installation is the reverse of removal.
