How to Fix Error Code 2 Flash

1. Turn Off Gas and Power

   Always turn off gas and wait for dissipation before working on gas appliances to prevent fire or explosion risk.

2. Remove Access Panel

3. Test Thermopile Voltage

   Be careful around the pilot flame and hot surfaces when taking measurements.

4. Disconnect Gas Lines

   Use proper wrenches to avoid damaging gas fittings. Cross-threading can cause dangerous gas leaks.

5. Remove Pilot Assembly

   Handle the pilot assembly carefully as the thermopile and thermocouple are fragile components.

6. Install New Pilot Assembly

   Ensure wires are connected to the correct terminals - thermopile to TH and thermocouple to TH/TR.

7. Reconnect Gas Lines

   Do not overtighten gas fittings as this can damage threads and cause leaks.

8. Test for Gas Leaks

   Never use an open flame to check for gas leaks. Always use leak detection solution.

9. Relight and Test System

10. Verify Error Code Resolution
