The thermocouple is usually the first thing to change. It controls the valve and the spark ignition is just to light the pilot.
No. The pilot valve is closed when no flame is sensed by the thermocouple.
A TNP valve is a temperature and pressure valve found on a water heater.
Pilot light would work but the main burner would not as the thermocouple proves that there is a pilot light to fire. The main gas valve would not open
T&P valve.
By shutting off the gas supply draining down the tank removing all the connections
To change the thermocouple on a Reliant 606 water heater, you will first need to turn off the gas supply and water heater. Remove the access panel, locate the thermocouple, unscrew it from the control valve, and disconnect it from the pilot assembly. Install the new thermocouple by reversing these steps, making sure it is properly positioned and secured.
To replace the thermocouple on a gas water heater, first turn off the gas supply and water heater. Locate the thermocouple near the pilot light and unscrew it from the control valve. Install the new thermocouple by screwing it into place and reassemble the water heater. Finally, turn the gas supply and water heater back on to test the new thermocouple.
THERMOCOUPLE or defective gas valve
To troubleshoot and replace a faulty thermocouple in a State Select water heater, follow these steps: Turn off the gas supply to the water heater. Locate the thermocouple near the pilot light assembly. Disconnect the thermocouple from the control valve. Remove the old thermocouple from the pilot assembly. Install the new thermocouple in the same position. Reconnect the thermocouple to the control valve. Turn on the gas supply and relight the pilot light. Test the water heater to ensure it is functioning properly. If you encounter any difficulties or are unsure about any step, consult a professional plumber for assistance.
A thermocouple on a gas heater operates by generating a small voltage when heated by the pilot flame. This voltage signals the gas valve to stay open, allowing gas to flow to the burner. If the pilot flame is extinguished, the lack of voltage from the thermocouple will cause the gas valve to shut off, preventing a gas leak.
The thermocouple is usually the first thing to change. It controls the valve and the spark ignition is just to light the pilot.
To test a water heater thermocouple, you can use a multimeter to check for continuity. Disconnect the thermocouple from the control valve and set the multimeter to the resistance setting. Touch one probe to the tip of the thermocouple and the other probe to the base. If the multimeter shows a reading of around 25-35 millivolts, the thermocouple is functioning properly.
Depends on the age of the heater. If you light the pilot with a match, you should be able to remove the thermocouple with the burner in place. The end that is in the flame will pull out of the clip that holds it. The control valve end unscrews. If you have a newer one that lights the pilot with a sparker, you have to remove the burner as a unit. There should be two screws holding the cover plate in place, the gas line to the burner, the thermocouple and the wire for the sparker. Disconnect all of these from the control valve and the unit slides out through the hole. Then change the thermocouple and replace.
It is most likely the thermocouple that is bad. That is what keeps the pilot light on. The thermocouple is the small tube that sits in the flame of the pilot and runs to the control valve.
It is one or the other. The thermocouple on a gas heater generates a very small current that keeps the gas valve open. A few micro volts. The thermocouple is the small tube that sits in the flame of the pilot light.
The thermocouple is the small tube that runs between the pilot light and the control valve. The valve end unscrews and the pilot light end in held in place with a spring clip that the tip pushes through. Unscrew the valve end and work the pilot end out by twisting it and pulling it out of the clip. Install a new one making sure the end is in the pilot flame and light the heater. No gas will come out when you take it loose from the control valve.
