I have a Whirlpool water heater that is only about 3 years old. About a year after we installed it, we had to replace the thermal couple (I think that's how you spell it) because the pilot was not staying on.

Well, it's happening again. When we notice there is no hot water in the house, we go outside and sure enough, the pilot is not on. We go through the procedure of turning it on, it does with no problem, but will later turn off. It may stay lit for an hour, or if we're lucky, overnight. Can't figure it out so we're assuming it's that little thermo couple again... Whirlpool customer service has us on hold forever, so I thought I'd turn to my buddies here at AMHD

Help...
