Why does my pilot light on my gas hot water heater keep going out?
If the pilot always relights, then I doubt that you have a bad thermocouple. when a thermocouple goes bad, you usually can’t relight the pilot. Another common thermocouple problem is a loose connection where the wire attaches to the control. Make sure the small nut holding the wire in is tight. Do not overtighten the nut! Finger tight then about 1/4 turn is tight enough. If you can turn the nut with your fingers, it needs to be tightened. Try this. With the burner on, reach up and feel around the draft diverter. That’s the little tin piece on top of the wtr htr that holds the vent pipe on top. Hold your hand near the opening and see if you can feel any heat coming out of the opening. You should not feel any heat coming from under the draft diverter. If there is heat pouring out of the opening, you may have a blocked flue pipe or rain cap on the roof. This can cause the burnt fumes from the burner to back up inside the wtr htr, and smother the pilot light when the burner goes off. Anoth
