What happens if the pilot does not light on a water heater?
The thermocouple detects the pilot flame. If the thermocouple does not detect a flame, the ignition process will stall, and the burner will not light…. The pilot ignites the water heater’s gas burner. If the pilot does not light, the water heater will not heat.
Why does my AO Smith water heater not light?
The spark electrode sends intermittent high-voltage sparks to light the pilot. If the spark electrode won’t produce sparks, it is likely defective. If the spark electrode is defective, replace it. We carry more than 4 million parts from over 175 major brands, so chances are, we’ve got the part you need.
What to do if your water heater is not lighting?
If the pilot is restricted, try removing it and clearing it with a stiff brush and/or compressed air. If the pilot cannot be cleaned, replace it. Some water heaters use a spark electrode to light the pilot flame. The spark electrode sends intermittent high-voltage sparks to light the pilot.
Why is my gas hot water heater not working?
The other less common problem would be the gas valve. A bad gas valve will not allow any gas to go to the burner or pilot light. If the pilot light lights and then shuts off it is not the gas valve. If it won’t light at all, see the article, ‘ Fixing Hot Water Heater Gas Valves ‘ for the issues surrounding this device.
