How does the thermostat work on a gas water heater?

The thermostat is a thermistor that responds to heat by producing a small electric current. The current increases when water temperature increases, and drops when temperature drops. Changes in the electric current cause gas control to turn ON and OFF. When gas control turns ON, it releases gas to burner.

Why are there two thermostats on a hot water heater?

A dual-element water heater uses two heating elements controlled by two separate thermostats. When it reaches a specified temperature, it shuts off, and the lower heating element takes over, heating the rest of the water. This is an efficient, money-saving feature, as the water is heated in a consistent manner.

How do I know if my gas valve is bad on my water heater?

If the burner stays on, turn the gas supply off and replace the gas valve. If the pilot is lit, you have a tank of cold water, the thermostat turned up and the burner does not fire up, either the burner orifice is clogged or the water heater gas valve is bad.

How do you replace a thermocouple on a gas water heater?

How to Replace a Water Heater's Thermocouple

Turn off the gas supply.
Unfasten the three nuts that hold the thermocouple and the two gas tubes to the valve.
Detach the thermocouple from the burner.
Install the new one the same way that you removed the old one.
Turn the gas back on and follow the lighting instructions on the water heater.

What causes a gas water heater to overheat?

A gas water heater will not be working as efficiently if there is sediment in the tank because they heat from the bottom of the tank. This can lead to the elements overheating, which is why your water heater is suddenly hot. The water can absorb this heat, but it can cause your water heater to overheat.

Where is the thermocouple on a water heater?

The job of the thermocouple The thermocouple is attached near the pilot light along the burner assembly, with the two ends of the metal placed in the flame of the pilot light, and the other end attached to a shut-off valve for the natural gas line that feeds gas to the burner.

How do you replace a thermocouple?

Replacing a Thermocouple

Shut off the gas and electrical power to the furnace.
Remove the furnace's access cover.
If the furnace has been running, wait 30 minutes for the thermocouple to cool completely.
Unscrew the nut that holds the thermocouple end fitting into the gas control valve, using an open-end wrench.

What causes a gas water heater to stop 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 it won't light at all, see the article, 'Fixing Hot Water Heater Gas Valves' for the issues surrounding this device. A clogged or partially clogged vent can also cause this problem.

How does a gas water heater valve work?

The gas control valve allows the pilot to be ignited, and the lit pilot heats the thermocouple. Once the water heater thermocouple is heated, it sends a signal to the gas control valve which allows the burner to operate, heating the water in the tank.

How does gas water heater thermostat work?

How does a natural gas valve work?

The furnace gas valve operates by electromagnets. The primary valve -- also known as the safety valve -- supplies gas to the pilot light. The second valve -- also known as the main valve -- allows gas to flow to the burner trays. Without adequate heating of the thermocouple or thermopile, the furnace gas valve closes.

How do I turn my gas water heater on?

Turn the gas regulator valve's knob to “Pilot,” press down on it and hold it down. This starts the flow of gas to the pilot burner. On some water heater models, you press and hold down a separate red button to start the pilot burner gas flow.
