Had the same trouble with one of my boilers and it was the thermal coupler that was shot.

I read that it could be the thermo coupler. But the unit is only 2 yrs old, do these things break down that quickly?

Yes they can burn out within a couple yrs depending on how often the water heater kicks in. The one for my boiler was only $25 and I was able to replace it with ease. If anything I think I would rather replace a thermal coupler every couple yrs then something more expensive.

If I'm not mistaken. A two year old water heater is sealed combustion with a flame arresting intake screen on the bottom/side (if it is naturally aspirated(metal chimney)). On the right of the burner viewing glass there's a manual limit switch. Check that. If I'm way off base, post the model #.
