Dometic Atwood Gas Control Valve | 92089 | 10 Gal DSI Water Heater

Restore safe, reliable propane delivery to your 10-gallon Atwood/Dometic RV water heater with the Dometic 92089 Gas Control Valve. This genuine Dometic OEM replacement gas valve controls propane flow to the burner on 10-gallon water heaters with Direct Spark Ignition (DSI) — the critical component that opens and closes propane flow based on signals from the control board. When the valve fails, the water heater either won't ignite at all or won't shut off properly.

For 10-Gallon Atwood / Dometic Water Heaters with DSI

The 92089 is specifically engineered for 10-gallon Atwood and Dometic water heaters with Direct Spark Ignition (DSI). Compatible models include:

• G10 Series: G10-1E, G10-2E, G10-3E
• GC10 Series: GC10-1E, GC10-2E
• GC10A Series: GC10A-2E, GC10A-3E, GC10A-4E
• GCH10A Series: GCH10A-2E, GCH10A-3E

Verify your existing water heater model on the manufacturer label before ordering — the 92089 is specifically for 10-gallon DSI models and is NOT interchangeable with 6-gallon water heater gas valves.

Extensive Cross-Reference Coverage

This valve has carried multiple part numbers across different generations and catalogs. The 92089 supersedes or is referenced under several other part numbers:

• 93844
• 93322
• 93870
• 93321
• 0713814310264

If your existing gas valve or service documentation shows any of those part numbers, this 92089 is the current production replacement.

How the Gas Valve Works

The 92089 is the critical component that controls propane flow to the burner:

• Opens via 12V DC signal from the water heater's control board when heat is demanded
• Allows propane flow to the burner where the DSI igniter lights it
• Closes when temperature setpoint is reached — shutting off propane supply
• Operates at low current draw (0.48 amps) — minimal load on the RV electrical system

Common Failure Symptoms

Common reasons to replace the gas valve include:

• Water heater won't ignite despite proper power, ignition spark, and propane supply
• Water heater fires but cycles erratically
• Valve doesn't close fully when commanded — gas continues flowing after shutdown
• Coil continuity testing shows failure in the valve solenoid
• Gas smell at the water heater indicating valve leakage
• Erratic flame quality

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

Genuine Dometic OEM Replacement

As a Dometic factory replacement part, the 92089 is built to original specifications for a precise drop-in fit in compatible 10-gallon DSI water heater installations.

⚠️ 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.

Considering Other Water Heater Upgrades?

While you have the water heater open for service, consider these other Dometic upgrade and maintenance parts:

• Dometic 93105 Adjustable Thermostat Control — upgrade from fixed-setpoint to adjustable 110°F–150°F temperature control (fits the same G10/GC10/GCH10A series this gas valve covers)
