Honeywell Gas Furnace Gas Valve Assembly Parts — Models & Compatibility

If your Honeywell or York furnace won't ignite, cycles on and off randomly, or produces a weak flame, the gas valve assembly is often the culprit. This hub covers the SV9501M2528 SmartValve — a direct replacement for several discontinued valve models including SV9501M2726 and SV9501M2718. This valve fits 20+ Honeywell Resideo and York furnace models across multiple tonnage ratings.

Is This the Right Gas Valve for Your Furnace?

Before ordering, you'll need your furnace's exact model number. Look inside the furnace cabinet door — there's usually a silver or white label with the model and serial number. For York units, check models starting with 1SS, 1SP, or 1LD. For Honeywell systems, look for D1NA or DAYA series designations.

Cross-reference your model number against our compatibility list below. The SV9501M2528 replaces older valve assemblies that are no longer manufactured, making it the go-to solution for many 2010-2020 era Honeywell residential furnaces.

About the SV9501M2528 SmartValve Assembly

This isn't just a simple gas valve — it's an integrated control module that regulates gas flow, manages ignition sequences, and communicates with your furnace's control board. The SmartValve design combines the gas valve, pressure switch connections, and electronic controls into one unit, which is why it carries a higher price point than basic valves.

Common failure modes include intermittent ignition (furnace tries to light multiple times before succeeding), complete no-heat situations where the inducer motor runs but ignition never occurs, or pressure switch errors that prevent the gas valve from opening. In many cases, the valve's internal electronics fail before the mechanical components do.

The SV9501M2528 valve works with both natural gas and LP configurations — the furnace's control board handles the fuel type adjustments. This valve is rated for furnaces ranging from 18,000 to 70,000 BTU input, covering most residential applications from 1.5-ton to 5-ton systems.

Compatible Furnace Models

This gas valve assembly fits the following Honeywell and York furnace models:

• D1NA024N03606C — Honeywell 24K BTU furnace
• D1NA024N05606C — Honeywell 24K BTU, 5-ton cabinet
• D1NA030N05606C — Honeywell 30K BTU furnace
• D1NA036N05606C — Honeywell 36K BTU, 5-ton
• D1NA036N07206C — Honeywell 36K BTU, 7-ton cabinet
• D1NH036N07206C — Honeywell 36K BTU horizontal
• DAYA-F018N045C — Honeywell 18K BTU compact
• DAYA-F024N070C — Honeywell 24K BTU, 7-ton cabinet
• 1SS04701 — York single-stage furnace
• 1SP0452 — York single-stage, 5-ton
• 1LD0470 — York low-profile furnace
• SV9501M2528 — Direct replacement part number
• SV9501M8129 — Honeywell alternate configuration

Note: Some model numbers may have suffix variations (letters/numbers at the end) that still use this valve. When in doubt, compare the existing valve's part number stamped on the valve body itself.

What You Should Know Before Installing

Gas valve replacement is not a DIY project for most homeowners. You're working with natural gas or LP — both of which require proper leak testing and combustion analysis after installation. Most jurisdictions require a licensed HVAC technician or gas fitter to perform this work legally.

The valve itself bolts to the furnace's gas manifold, typically with two or three bolts. Electrical connections include the main valve harness (usually a multi-pin connector) and ground wire. Gas connections use pipe thread fittings that must be sealed with proper pipe dope rated for gas use — never use Teflon tape on gas fittings.

After installation, you'll need to check gas inlet pressure, manifold pressure, and perform a full ignition cycle test. The valve's pressure switch ports must be properly connected and tested for response. Skip any of these steps, and you risk unsafe operation or intermittent failures that'll have you back inside the furnace within weeks.

Why This Valve Fails

The integrated electronics are the weak point. Over years of heating cycles, thermal stress cracks solder joints on the internal circuit board. Voltage spikes from lightning storms or power grid fluctuations can also fry the control circuitry. Less commonly, the valve's solenoid coils wear out or the internal gas seals deteriorate.

If your furnace is stuck in a lockout condition (flashing error codes), won't ignite after the inducer runs, or clicks repeatedly without lighting, the gas valve is a likely suspect. However, always verify that you're getting proper voltage to the valve (24VAC) and that all pressure switches are functioning before replacing the valve — bad diagnostics lead to unnecessary part swaps.

Price and Availability

The SV9501M2528 retails for $466.99 — reflective of its integrated SmartValve design. While that's a significant investment, it's considerably less than a full furnace replacement. Factor in professional installation (typically 1-2 hours of labor), and you're looking at a total repair cost in the $650-$800 range depending on your area's labor rates.

This part is in stock and ships directly. Given that this valve replaces discontinued models, availability is critical — older furnaces can't use generic valves due to the proprietary electronic controls.

Need Help Identifying Your Part?

If you're not sure whether this valve fits your furnace, snap a photo of your existing gas valve (get the label with part numbers visible) and your furnace's model number plate. Our parts specialists can cross-reference the numbers and confirm compatibility before you order. It beats guessing and eating return shipping costs on a $467 part.
