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.
A hot water heater thermocouple can go bad repeatedly due to factors such as excessive heat exposure, corrosion, or poor installation. It's important to check for proper venting, gas pressure, and pilot flame adjustment to prevent premature failure of the thermocouple. Regular maintenance and ensuring all components are functioning correctly can help prevent repeated failures.
The pilot may not be lighting due to a problem with the gas supply, a faulty thermocouple, a clogged pilot tube, or a malfunctioning control valve. Check for gas supply, ensure the pilot area is clear of debris, and consider replacing the thermocouple if necessary.
"How much" as a question is quite vague. Some hot water heaters are comprised of copper only. So this now depends on the size of the hot water heater. Some hot water heaters have no copper whatsoever.
There could be several reasons your hot water faucet only has lukewarm water. Possible issues include a malfunctioning water heater, a problem with the hot water supply line, or a faulty faucet valve. It's best to contact a plumber to diagnose and fix the problem.
A properly functioning hot water heater should not give off bad fumes. However, if you notice any unusual odors coming from your hot water heater, it could indicate a potential gas leak or another issue that requires immediate attention from a professional.
There are many pictures of this on Google.
$6 to $10 depending on where you are and where you get it from.
THERMOCOUPLE or defective gas valve
Sounds like you need a thermocouple.
You do NOT clean a thermocouple. They are really inexpensive and when they are giving problems have a LMP / or Gas fitter replace it

Your hot water heater may not stay lit due to issues with the thermocouple, gas supply, or ventilation. It is important to have a professional inspect and repair the heater to ensure safe and efficient operation.
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.
The hot water heater pilot light may not stay lit due to issues with the thermocouple, gas supply, or ventilation. It is important to troubleshoot and address these issues promptly to ensure the proper functioning of the water heater.

The pilot light on your hot water heater may keep going out due to issues with the thermocouple, a draft in the area, or a problem with the gas supply. It is important to have a professional inspect and repair the heater to ensure safe and reliable operation.
