AtwoodPart 93844 / NBK 20342Made in USAAtwood 93844 Gas Valve for DSI RV Water Heaters

When your Atwood water heater stops lighting or fails to maintain a flame, the gas valve is often the culprit. This is the genuine direct-replacement gas valve for Atwood water heaters equipped with Direct Spark Ignition (DSI) -- covering a wide range of 6-gallon and 10-gallon units. Backed by a 2-year manufacturer warranty and made in the USA, this valve restores reliable hot water to your rig without guesswork.

Restore Hot Water to Your RV -- the Right Valve for the Job

Atwood DSI water heaters use a combination gas valve that controls gas flow and works in coordination with the DSI ignition board to light and regulate the burner. When the valve fails, symptoms include no ignition, intermittent pilot outages, or the heater refusing to stay lit. Replacing the valve with the correct OEM-spec part -- Atwood 93844 -- brings the system back to factory performance.

This valve is also cataloged under NBK part number 20342, so if you sourced a quote from an RV service center using that number, this is the same part. It fits a broad range of Atwood 6-gallon and 10-gallon DSI water heater models commonly found in travel trailers, fifth wheels, and Class A and C motorhomes.

Direct Fit Replacement

Engineered to match original mounting positions, inlet/outlet orientation, and wiring connector on compatible Atwood DSI heater models. No adapters required.

Wide Model Coverage

Fits over 40 Atwood DSI water heater model numbers across the 6-gallon and 10-gallon product families -- see full compatibility list below.

Made in USA

Manufactured in the United States to meet Atwood quality standards for gas appliance components used in RV applications.

2-Year Warranty

Covered by a 2-year manufacturer warranty against defects -- longer coverage than many aftermarket alternatives.

What is DSI (Direct Spark Ignition)?

DSI water heaters ignite the burner electronically with a direct spark -- no standing pilot light. The gas valve works in tandem with the DSI control board: when the board signals for heat, the valve opens and the spark fires simultaneously. A faulty valve that fails to open (or fails to hold open) is one of the most common causes of DSI ignition failure.

Cross-Reference Numbers: Atwood 93844 -- NBK 20342. If your service quote or parts list shows NBK 20342, this is the same component.
Verify Your Model Number Before Ordering: The model number label on your Atwood water heater is typically located on the exterior access panel or inside the compartment door. Confirm your model appears in the compatibility list above. Not all Atwood water heaters use this valve -- pilot-ignition (non-DSI) models require a different part.
Installation Tips:
  • Turn off the LP gas supply at the tank before beginning any work.
  • Disconnect shore power or turn off the inverter before touching any wiring.
  • Allow the water heater to cool completely before removing the old valve.
  • Transfer the wiring connector and gas fittings carefully -- do not overtighten brass fittings.
  • After installation, test for gas leaks at all connections using approved leak-detection solution before restoring power or gas.
  • Cycle the heater through a full ignition sequence and confirm steady operation before buttoning up the access panel.
