I've got a new Reliance 606 water heater (5 months old) that was working fine until about a month ago. Now the pilot light will go out at random times, sometimes it won't go out for days or weeks, some days it will go out several times. It's always easy to relight, but annoying. When it's heating the water, I hear a constant "snapping" noise about every 20-30 seconds coming from inside the unit. The pliot flame is a lazy blue color, more or less, and seems to be contacting the thermocouple nicely. Any suggestions?
Thanks, Ron
