OEM Carrier Gas Valve EF680015 24V 1/2" Natural/LP for Model YAC42110YACX302AK

This OEM combination gas valve is the factory-specified replacement for the Carrier YAC42110YACX302AK furnace. The gas valve is the critical component that controls and regulates the flow of fuel to the burners on every call for heat. When this valve fails, the most common symptoms are a complete no-heat condition, repeated ignition lockouts with no flame established, or intermittent heating where the burners fail to light despite a functioning igniter and flame sensor. A failed gas valve will not pass gas regardless of how many times the board attempts an ignition sequence.

  • Specs: OEM Part # EF680015 | 24V coil voltage | 1/2" inlet × 1/2" outlet | Single-stage, slow-opening | Rated for Natural Gas (NG) | LP conversion kit included | 24 VAC at 50/60 Hz | 0.28A draw | Max inlet pressure: 1/2 PSI
  • OEM vs Generic: This is a genuine Carrier OEM valve engineered to exact factory pressure-regulation tolerances. Aftermarket valves may not meet the precise W.C. outlet pressure spec required by your heat exchanger, risking nuisance lockouts, incomplete combustion, or voided equipment warranties.
  • Install difficulty: 3/5 — Gas valve replacement requires shutting off the gas supply upstream, relieving line pressure, and carefully transferring all wiring connectors. Tools needed: pipe wrench, adjustable wrench, gas leak detector solution or electronic sniffer, multimeter, and a 1/4" nut driver. Always verify outlet pressure with a manometer after installation. We recommend a qualified HVAC technician for this repair.
  • Warranty: 1-year OEM manufacturer warranty. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Designed as the direct OEM replacement gas valve for Carrier model YAC42110YACX302AK. Verify your unit's data plate voltage (24V) and inlet connection size (1/2") before ordering. Not sure it fits? Our HVAC parts specialists verify fitment at no charge before you buy — contact us before placing your order.
