This is a Brand New replacement for a Carrier/Bryant/Payne/Day & Night furnace Control Circuit Board Panel! This aftermarket board replaces many older boards Carrier/Bryant/Payne/Day & Night Control Boards! See the list of obsolete part #s replaced by this board below!! Thanks for looking and good luck!
The control board is the "brain" of your unit, coordinating and executing the operation of other various components by sending voltage when and where needed. A control board is constantly monitoring sensors and safety switches in the unit.
