Suburban Furnace Solenoid Gas Valve | 161132 | P-40/P-40B/P-40S

Restore safe, reliable propane delivery to your Suburban P-40 series RV furnace with the Suburban 161132 OEM Solenoid Gas Valve. This genuine Suburban replacement gas valve controls the flow of propane to the burner based on signals from the furnace control board — featuring a dual-solenoid safety design for redundant leak protection and an integrated pressure regulator that automatically maintains the correct burner supply pressure. The right replacement when your existing valve has failed, leaks, or operates erratically.

For Suburban P-40 Series Furnaces

The 161132 is specifically engineered for the Suburban P Series furnaces:

• Suburban P-40
• Suburban P-40B
• Suburban P-40S

Verify your furnace model on the manufacturer label before ordering — Suburban makes multiple gas valves, and they are not interchangeable across different furnace model series.

How the Gas Valve Works

The 161132 is the critical component that controls propane flow to the burner:

• Opens via 24V DC signal from the control board when heat is demanded
• Allows propane flow to the burner where the igniter electrode lights it
• Closes when the call for heat ends — shutting off propane supply
• Regulates supply pressure via the integrated pressure regulator (9.5–10.5 in. WC)

Dual-Solenoid Design — Built-In Safety Redundancy

One of the standout safety features of the 161132 is its dual-solenoid construction. Rather than relying on a single valve mechanism to control gas flow, the dual-solenoid design provides redundant leak protection:

• Two valves perform the same task — both must open for gas to flow
• If one valve fails or seals imperfectly, the other still provides shutoff protection
• Provides backup protection against gas leakage through valve seals
• Meaningful real-world safety benefit — a single-valve failure mode that could leak gas into the furnace cabinet is mitigated by the second valve

That redundant design is what makes the dual-solenoid valve the safer engineering choice for RV furnace applications.

Integrated Pressure Regulator

The 161132 includes an internal pressure regulator that automatically reduces incoming propane pressure to the correct range for the burner:

• Output Pressure Range: 9.5 – 10.5 in. WC (Water Column)

Proper supply pressure is critical for clean combustion, efficient operation, and consistent flame quality. The integrated regulator means you don't need a separate external regulator at the furnace — the valve handles pressure management automatically.

Common Failure Symptoms

Common reasons to replace the gas valve include:

• Furnace won't ignite despite proper power, ignition spark, and air flow
• Furnace fires but cycles erratically
• Valve doesn't close fully when commanded — gas continues flowing after shutdown
• Coil continuity testing shows failure in one or both solenoids
• Gas smell at the furnace cabinet indicating valve leakage
• Improper supply pressure at the burner
• Erratic flame quality from pressure regulation issues

Before assuming the valve has failed, rule out simpler issues like low propane supply pressure, failed igniter electrode, blocked burner, control board issues, or wiring problems — these can mimic valve symptoms.

Genuine Suburban OEM Replacement

As a Suburban factory replacement part, the 161132 is built to original specifications for a precise drop-in fit in compatible P-40 series furnace installations.

Paired Component — Replace the Gasket Too

Whenever you replace the gas valve, it's smart practice to also replace the electrode and burner door gasket — you've already opened the burner door for the valve replacement, and a fresh gasket is cheap insurance against air infiltration or combustion gas leaks. The matching gasket for P Series furnaces is the Suburban 525011 Electrode Gasket — covers P-40, P-40B, P-40S, and the entire NT Series too.

⚠️ Professional Installation Required

Gas valves should be installed and tested by a qualified RV service technician. Improperly installed propane components are a fire and explosion risk. Always pressure-test connections after installation and verify proper valve operation including both solenoids before returning the furnace to service.
