The pressure switch monitors negative pressure (draft) generated by the inducer motor to confirm safe combustion venting before allowing the gas valve to open. On a two-stage furnace like the PG9UAA060100AASA, a \u003cem\u003edual\u003c\/em\u003e pressure switch monitors both the low-fire (Stage 1) and high-fire (Stage 2) inducer pressure levels independently. When it fails, the furnace will lock out before ignition — often flashing a fault code for \"pressure switch stuck open\" — leaving you with no heat.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Dual pressure switch assembly | Stage 1: –0.81\" W.C. | Stage 2: –1.60\" W.C.
