- The B1370159 Goodman Furnace Pressure Switch which is attached to the draft inducer motor by small pressure switch tubing. The pressure switch senses the negative pressure created by the draft inducer and closes the circuit between the two wires on the pressure switch. The pressure switch closes the circuit which goes to the control board. When the negative pressure is detected and the closed circuit is sent to the circuit board this allows the furnace to operate.
- If you have a stopped up draft inducer or the draft inducer hole where the pressure tubing attaches to the draft inducer is stopped up then this will cause the pressure switch to not sense pressure and work properly.
