Last week, my water heater stopped heating. My wife and I both tried to light the pilot according to the instructions, but it wouldn't start. We called Whirlpool's hot-line. Some Indians told us to check the gas line and so forth. No luck. (The furnace is running fine and there's only a few feet of pipe between the furnace and the water heater, so there's not a lot possible points of failure.)
I then called a plumber. He came out and the lit the thing with no trouble. (I'm sure he thought we were ignorant, and he might be right.) He suggested that it might have gone out because of failing thermocouple. He checked for leaks, charged me $60, and left.
I got one tank of hot water and then the pilot went out again. I couldn't restart it. I'm not seeing a spark, but I don't really know if I should expect that behind the window.
It seems to me that I should get gas in the pilot position with the override button pressed even with a defective thermocouple. Is that right? I felt pretty good about that idea until I read this:
Should I perhaps be looking for gas or air restrictions or replacing a thermocouple?
Any advice or information is appreciated.
