This is the factory OEM combination gas valve for the Carrier PG8JAA036045AGJA packaged gas/electric unit. The gas valve is the critical component that controls natural gas flow to the burner assembly on every call for heat. When it fails, the furnace will typically attempt ignition, then lock out with no flame — leaving you with zero heat output. A faulty valve may also cause delayed ignition, intermittent heating, or fault codes related to gas flow on the control board.
Compatibility: Fits Carrier model PG8JAA036045AGJA packaged gas/electric unit. Cross-references: White Rodgers 36J24-618, PEF32CW210, 9D1238. Always verify your unit's gas type (natural gas vs. LP) and inlet pressure rating on the data plate before ordering. Need fitment help?
