If you have had your heater for more than a few years your better off to replace the whole thing! Besides you may not even be able to find the part in the first place! If you have no experience with gas you best leave it to the pros! I was in the gas business for several years and it can be very dangerous! ...A guy jumps out of an airplane and finds his ripcord won't work! when he looks down he sees a guy coming up towards him. Hey do you know anything about parachutes? the guy says no,sorry! Do you know anything about gas water heaters?...Funny but it is worth thinking about!
