This OEM combination gas valve (part# EF32CW210) is the factory-specified replacement for the Carrier PG8MEA048070AAJA gas furnace. The gas valve is the heart of your furnace's fuel delivery system — it receives the 24V signal from the control board, opens to allow natural gas flow to the burners, and regulates manifold pressure to the factory-set 3.5" W.C. When the valve fails, the furnace will attempt ignition, spark, or glow normally but produce no heat, triggering a lockout fault code. A faulty valve can also cause intermittent heating, delayed ignition, or a complete no-heat condition.
Compatibility: Direct OEM replacement for Carrier PG8MEA048070AAJA packaged gas furnace. Verify fuel type (natural gas) and inlet/outlet pipe size (1/2" NPT) against your unit's data plate before ordering. Need help confirming fitment? Our HVAC parts specialists verify compatibility before you buy — no guesswork, no returns.
