This OEM combination gas valve is the factory-specified replacement for the Carrier PG8JAA066110ADJA gas furnace. The gas valve is the critical component that controls natural gas flow from the supply line into the burner assembly. When it receives a 24V signal from the control board after a successful ignition sequence, it opens to allow gas flow for combustion. A failed gas valve typically results in a complete no-heat condition — the inducer and igniter may cycle normally, but the burners never light. In some cases, you may hear clicking or see fault codes indicating valve failure or no gas pressure sensed.
Compatibility: Designed for the Carrier PG8JAA066110ADJA packaged gas furnace. Always verify your unit's data plate voltage (24V) and gas type (natural gas) before ordering. Cross-reference OEM part number EF32CW210 and superseded part number 36J24-618 to confirm fitment. Have questions? Our HVAC parts specialists verify fitment before you order — reach out before you buy.
