Over time, the gas control valve may begin to operate improperly, and the heating assembly — commonly referred to as the burner — may also require replacement due to normal wear and tear.
To perform this repair safely, the water supply to the water heater is completely shut off and the gas supply is disconnected. The tank is then fully drained before removing the gas control valve. The burner assembly located at the bottom of the unit is carefully disassembled, and the necessary components are replaced.
After installation, all gas connections are properly reassembled and secured. The water supply is restored to refill the tank before restarting the unit. Finally, the water heater is tested to ensure safe ignition, proper operation, and correct overall performance.
