Suburban Water Heater Gas Valve 161112 (SW3P / SW6P)

The Suburban 161112 Water Heater Gas Valve is an OEM thermostat and propane gas control used on select Suburban pilot-ignition RV water heaters. This valve controls propane flow to the pilot and main burner while regulating water temperature during operation.

Suburban 161112 is designed for older pilot-style water heaters and is not used on Direct Spark Ignition (DSI) models such as the SW6D or SW6DE.

SW3P

• SW3P

  • Serial number 95340119 and above — Suburban 161112 is the correct gas valve for your model

  • Serial number 95340118 and below — an earlier gas control may be required; verify the original valve before ordering

SW6P

• SW6P

  • Serial number 95340119 and above — Suburban 161112 is the correct gas valve for your model

  • On later SW6P production, another gas control may apply depending on serial number, so verify the data plate if your unit falls into a later production range

SW6PR

• SW6PR

  • Serial number 95340119 and above — Suburban 161112 is the correct gas valve for your model

SW6PER

  • Serial number 95340119 and above — Suburban 161112 is the correct gas valve for your model

Important: Suburban 161112 is intended for pilot-ignition water heaters, including SW3P, SW6P, SW6PR, and SW6PER models after serial number 95340118. Always verify the model and serial number on the water heater data plate before ordering.

Signs of a Bad Suburban Water Heater Gas Valve

Common symptoms include:

• Pilot light will not stay lit

• Pilot operates but the main burner does not ignite

• Burner does not receive propane

• Water temperature does not regulate properly

• Burner fails to cycle on and off correctly

• Gas control knob becomes difficult to operate

• Internal thermostat or gas control fails

Estimated Installation Time

30–60 minutes

Tools Required

• Adjustable wrench

• Open-end wrenches

• Screwdriver

• Approved propane leak detection solution

Potential Issues

Before replacing the gas valve, inspect the pilot burner, thermocouple, propane supply, burner assembly, gas connections, and pilot flame. A weak pilot flame or failing thermocouple can cause symptoms similar to a defective thermostat gas control.

Because Suburban used multiple gas controls throughout production of its pilot-model water heaters, always verify both the model and serial number before ordering.

After installation, carefully check all propane connections for leaks before operating the water heater.

If your Suburban SW3P, SW6P, SW6PR, or SW6PER has a serial number above 95340118, Suburban 161112 is the applicable thermostat gas control for that production range.
