The Carrier EF660015 gas valve (sold under the Bryant and Carrier names) is a 24V furnace valve offered as an OEM-style replacement part. Retailer listings describe it as a 1/2 inch natural gas valve with a 3.0 inch water column setting and an LP conversion kit, so it is not a propane-only part. Confirm your furnace model and the old valve’s part number before you order, and have a qualified technician fit it.
This guide is based on retailer and Amazon listings; the valve was not hands-on tested. It is a fit-check and safety guide, not an installation manual.

Is the Carrier EF660015 gas valve right for your furnace?
- Find the model and serial number on the furnace rating plate and look the valve up in the manufacturer’s parts list.
- Match the old valve’s part number, voltage, pipe size, inlet and outlet position and fuel type.
- Check whether your furnace runs natural gas or propane. If propane, the LP conversion kit and the correct pressure settings must be used.
- Confirm that the valve is a direct replacement, not a different control with a different wiring layout.
Installing a replacement gas valve
Gas valve replacement involves gas piping, electrical wiring and combustion settings, and local codes may require a licensed professional. The general order of work looks like this:
- Switch off power and close the gas shut-off valve.
- Label and disconnect the wires, then remove the old valve.
- Fit the new valve with a thread sealant approved for gas, and tighten without over-torquing.
- Reconnect the wiring to the labeled 24V terminals.
- Restore gas and power, then check every joint for leaks with a leak detector solution.
- Check the manifold pressure and operation against the furnace manual.
If you smell gas, leave the building and call your gas supplier or emergency services. Do not operate switches.
Common problems to check first
- Furnace will not light: check the flame sensor, igniter, pressure switch and wiring before you replace the valve.
- No 24V at the valve: the fault is upstream, in the control board or safety circuit.
- Gas smell at the valve: shut off the gas and have the joints checked.
