Manufactured by White-Rodgers (model 36J55-503), it is a 2-stage valve that regulates natural gas flow through both low-fire and high-fire stages, allowing the furnace to modulate heat output for maximum efficiency and comfort. When this valve fails, the furnace will typically lock out after an ignition attempt with no gas flow, produce a fault code for gas valve failure, or fail to transition from low-stage to high-stage firing — leaving the home without heat.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 24V coil voltage | 0.430A draw | 2-stage (low\/high fire) | Natural gas | White-Rodgers 36J55 Type 503 | Replaces OEM part number EF33CW191\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM part, factory-matched to exact design life, pressure ratings, and safety certifications for the PG9UAA042080AASA.
