Intertherm Furnace Gas Burner & Control Valve Parts

Intertherm Furnace Gas Valve & Burner Control Parts

The gas valve (also called a gas control valve or thermostat valve) is the gatekeeper of your Intertherm furnace — it opens and closes based on signals from the igniter and flame sensor to release gas into the burner assembly. When your furnace ignites but won't sustain flame, or won't ignite at all, the gas valve is often the culprit. Intertherm furnaces, especially in manufactured housing applications, rely on precise gas valve timing and pressure to keep you warm.

If your furnace is clicking the igniter repeatedly but gas never lights, or if you smell gas but no flame appears, a faulty gas valve may be preventing fuel flow. Always verify inlet and outlet pressure before replacing — sometimes a bad igniter or flame sensor is the real issue. We carry OEM Intertherm gas valve assemblies and burner control parts that match your model's exact specifications.

• Gas valve won't open: Igniter glows but no gas, or furnace clicks repeatedly — check for 24V signal at the solenoid
• Gas valve stuck open: Smell of gas, yellow flame at burner, or furnace won't shut off — dangerous; replace immediately
• Low or no flame: Weak burner ignition or slow heat-up — gas pressure may be low or valve partially stuck
• Burner control board failure: No signal to open valve, error code or LED fault indication — control board replacement needed
• Thermostat valve response: Furnace overshoots or undershoots target temperature — older mechanical thermostats may wear out

Intertherm Gas Valve & Burner Parts — Frequently Asked Questions

What's the difference between a gas valve and a burner control valve?

In Intertherm furnaces, these terms are often used interchangeably. The gas valve is the solenoid-operated part that opens to allow gas flow when the igniter is hot and the control circuit sends a signal. The burner control valve assembly may include the gas valve, pressure regulators, and safety shutoffs all in one unit. OEM Intertherm assemblies are built as single units — replacing just the solenoid alone is not typically an option, so you'll order the complete valve assembly for your model.

How do I know if my Intertherm furnace has a gas valve problem vs. An igniter problem?

Listen and observe: if you hear the igniter clicking/buzzing and see it glow orange but smell no gas and see no flame, the igniter is working but gas isn't flowing — that points to the gas valve. If you hear the igniter click once or twice and stop, or the igniter never glows at all, the igniter itself is likely bad. You can also use a multimeter to check for 24V at the solenoid terminal when the furnace calls for heat — no voltage = bad control board; voltage present but no gas = bad valve.

Why do Intertherm furnaces in manufactured homes need special attention for gas valves?

Intertherm and Miller furnaces are the standard in mobile home heating. These furnaces operate at specific pressures and gas flow rates tuned to mobile home ducting and BTU requirements. Using an aftermarket or mismatched gas valve can cause improper burner flame, safety shutoffs, or heating inefficiency. Always use OEM Intertherm/Nordyne gas valves for your model — the part number and pressure rating are critical.

What should I check before replacing a gas valve?

First, verify your model number and confirm the gas valve part number. Second, check that the igniter is glowing and the flame sensor is clean (use fine steel wool). Third, use a manometer to measure inlet and outlet gas pressure — if pressures are normal but the valve still won't open when 24V is applied, the valve solenoid has failed. Fourth, confirm the control board is sending 24V to the solenoid during the call for heat — a bad board won't open the valve no matter how good the valve is.

Intertherm Furnace Model Number: Where to Look

Intertherm places the model number on a data plate inside the front access panel of most furnaces. You may also find it on the blower compartment door or near the gas valve. Look for a label showing "Model" or "Model Number," and copy every letter, number, and hyphen exactly as printed. Type it into our model number lookup and the catalog narrows to parts made for your unit, including the parts throughout the furnace, not just the gas burner or control valve. Using the complete model number helps match the furnace's design and specifications, so you can select compatible parts without sorting through unrelated results.
