I am having problems lighting my hot water heater. My camper has an Attwood water heater. When I try to light the heater, it will light for about 5 seconds and then go back out. Has anyone had this problem before. What needs to be replaced.
Common problem easy to fix. Remove burner tube and check the condition of the electrodes. Should be smooth with no swelling and cracking and should sit just to the top of the outlet. If all is OK remove the board and have it tested at your local reputable shop.
