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.
To replace a Honeywell water heater thermocouple, first turn off the gas supply and water heater. Remove the access panel and locate the thermocouple. Disconnect the old thermocouple and install the new one in the same position. Reassemble the access panel and turn on the gas supply and water heater to test the new thermocouple.
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.
The water heater pilot light may not stay on due to issues with the thermocouple, gas supply, or a dirty pilot light. It is important to check and potentially replace the thermocouple, ensure proper gas flow, and clean the pilot light to resolve the issue.
To test a thermocouple on a water heater, you can use a multimeter to measure the voltage output. Disconnect the thermocouple from the control unit and place the multimeter probes on the thermocouple terminals. A functioning thermocouple should produce a voltage reading within the expected range. If the reading is outside this range, the thermocouple may need to be replaced.
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 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.

$6 to $10 depending on where you are and where you get it from.
Most likely the thermocouple is bad. The thermocouple is the little tube that sits in the flame of the pilot light. Runs from the pilot light to the control valve. Very simple to replace. Costs about $6.
Usually less than 1 hour work, ( but nobody will bill one hour) Part costs less than $10 and any competent handyman can do it.
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.
