The pressure switch monitors the negative pressure created by the inducer motor, proving that combustion airflow is adequate before allowing the gas valve to open. When this switch fails or sticks, the furnace will attempt ignition and then go into lockout — or in many cases, will not advance past the inducer-on stage at all.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e LP (propane) gas pressure switch | 6.5 in.
