I've had a ST29SS for 4 years now. Last camping trip the Attwood HWT worked on both electric and gas. This camping trip neither are working. There's water in the tank, the fireplace HWT switch is in the correct position, and the switch for electric is lite. Tank is ice cold. Gas burner also won't light. Everything else in the trailer is fine. Thanks for any ideas.
