Manufactured by White Rodgers (model 36J55-503), this 2-stage valve precisely regulates natural gas flow at two firing rates — low-stage for efficient partial-load heating and high-stage for maximum heat output on the coldest days. When this valve fails, the furnace will typically enter a no-heat lockout condition: the inducer and igniter will cycle, but no gas will flow, resulting in repeated ignition attempts with no flame establishment and ultimately a hard lockout fault code.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 2-Stage Natural Gas | 24V AC coil | 1\/2\" NPT inlet × 1\/2\" NPT outlet | Hi-stage: 3.5\" W.C. | Lo-stage: 1.5\" W.C. | Replaces OEM P\/N EF33CW191\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM part — not an aftermarket substitute. OEM valves are factory-tested to exact pressure and flow specifications for the PG9MXA060120AASA.
