What the Gas Valve Assembly Does
A gas valve assembly controls fuel delivery to your furnace burners. Most control boards and thermostats send a 24 V control signal to operate the valve during a call for heat.
The valve holds gas back until ignition begins. Once the heating cycle finishes, the valve closes tightly to stop fuel flow.
If safety controls detect an issue, the valve remains closed. Never bypass a flame sensor, pressure switch, limit switch, or rollout switch to force the valve to open.
Understanding the Specs for 32544123000
Matching the physical size and pressure ratings of your valve is critical for safe heating operation.

Confirming a Replacement Matches
Check your old component carefully before seeking a replacement. You must confirm the gas type, such as natural gas or propane as listed for your setup.
The replacement must match the pipe size and BTU rating for your furnace. It must also match the ignition type of your heating unit.
This part number replaces several older numbers. It replaces S1-02530789000, S1-02530888000, S1-02531969000, S1-02531996000, S1-02532643000, S1-02535317000, S1-02537426000, S1-02632643000, S1-2702-326P, S1-2702-331P, S1-32537426000, and S1-36F24-206.
Signs of Failure and Safe Replacement Steps
A faulty valve may stop burners from lighting even when the igniter glows and safety switches close. Always check basic causes first. For example, if burners light and go out after 3 to 10 seconds, a dirty flame sensor is a common cause.
Before handling any wiring, take a photo of every wire. Move wires one at a time to the matching spots on the replacement control.
Never attempt to bypass safety devices to diagnose a bad valve. Always ensure the shutoff valve on the gas line is turned completely off before working.
Read your old part
- Locate the rating label on your existing gas valve assembly.
- Wipe away dust to read the model or part number clearly.
- Check if the label displays part number 32544123000.
- If not, check if your number matches a listed replacement number such as S1-02537426000 or S1-32537426000.
- Verify your furnace ignition uses Direct Spark or Hot Surface ignition.
When to call a pro
Gas valve work means opening gas lines and setting gas pressure. A licensed tech should do it. Hire a licensed HVAC technician for any step you are not sure you can do safely.
Questions
What control voltage operates this gas valve?
Most home thermostats, contactor coils, and control boards use a 24 V control signal from a transformer to operate components like this valve.
What ignition systems work with part 32544123000?
This valve is rated for systems using Direct Spark or Hot Surface ignition. Verify your furnace ignition type matches before installing a replacement.
What should I do if I smell gas around the furnace?
If you smell gas, do not touch any switch. Leave the house right away and call your gas company from outside.
Can I replace the gas valve myself?
Gas valve work means opening fuel lines and setting manifold pressure. Because of the safety risks, we strongly suggest a licensed pro completes the install.
