Lennox Blower Control Board, Product Number 46K65
A blower control board is a circuit board that regulates the speed at which the blower turns. It has a terminal block that connects to a rung wire which goes to the blower.
The blower control board is an in-line low voltage system requirement for two stage blowers. It generates 24 Volt for Electronic Control Boards that utilize it.
Never run out of heating and cooling again! Lennox Blower Control Boards are designed to detect a fault in the blower motor and then activate the blower protector relay to continue turning the fan at low speed. This helps to automatically prevent blower burnout while ensuring proper air circulation.
