Hi guys
I have a Lennox LGK075-H-2M, the pressure differential switch has disintegrated and I can’t get one like yesterday, does anyone know if I can by- pass the switch temporarily to help the customer, this switch tells the unit whether the fan has failed or filters have blocked, etc, it connects to the KP01 board, 18 volt output, I need to know if we can do this safely without damaging the PCB board.
Thanks
AL
