Gas Water Heater-Pilot light on, but water not getting heated :(
Everything was working fine until 3 days before. Then we stopped getting hot water . I checked and saw that the pilot light was ON - no problem there. But the burner wasn't firing. I tried increasing the temperature in the thermostat, and the burner fired briefly (around half hour I guess). Then it stopped - but the pilot light is still on.
My guess is the thermostat may be malfunctioning. Or is there anything that could have tripped it up, that I can reset ? Any help useful, thanks so much!
