The pilot could be dirty and may be too weak to heat the thermocouple properly.
Most of the time it comes down to replacing the thermocouple.
ANS 2 The thermocouple costs less than $19 and can be changed in about 30 minutes. Best to first Shut off gas, and remove your one, then take to the store for comparison. There are 5-6 different types but all very similar. Honeywell Universal is good for many heaters. This is essentially a thin copper tube 18 -30 inches long, with a metal bulb at one end and a hollow nut at the regulator end. Many good instructions on internet about how to do it
What else can I help you with?
If the pilot light goes out on your hot water heater is it dangerous or harmful?
No, it is not dangerous. (Unless you are working with a water heater that is 20+ years old.) In any modern hot water heater, if the pilot light goes out a fail-safe will go off - preventing gas from leaking out. Also, there is a sensor so if there is not enough air-flow or oxygen with the water heater, it will shut off the gas.
If a pilot light goes out in a gas water heater does the gas keep running?
No because water heaters have a safety valves and when the pilot light goes out the safety valve shuts off the gas
Why does the water heater pilot go out after turning the temperature control dial?
The water heater pilot goes out after turning the temperature control dial because adjusting the temperature can cause a change in the gas flow, which may extinguish the pilot light.
How do I properly light the pilot on my water heater?
To properly light the pilot on your water heater, follow these steps: Locate the pilot light button or knob on the water heater. Turn the knob to the "pilot" setting and hold it down. While holding the knob down, use a long lighter to ignite the pilot light. Keep holding the knob down for about 30 seconds after the pilot light is lit. Release the knob and turn it to the "on" position. If the pilot light goes out, repeat the process. If it continues to go out, there may be an issue that requires professional assistance.
What should I do if the pilot light goes out on my water heater?
If the pilot light goes out on your water heater, you should follow the manufacturer's instructions to relight it. This typically involves turning off the gas supply, waiting a few minutes, and then relighting the pilot light according to the appliance's manual.

Why does water heater pilot light go out when gas is turned on?
If the pilot light goes out when the gas is turned on, it could be due to a dirty or faulty thermocouple, a clogged pilot tube, or a problem with the gas supply. It's important to have a professional inspect and repair the water heater to ensure it is functioning safely and effectively.
What is the function of a thermocouple in a gas heater?
A thermocouple in a gas heater is a safety device that detects if the pilot light is on. If the pilot light goes out, the thermocouple shuts off the gas supply to prevent a dangerous gas leak.
What is a water heater thermal coupler?
Thermocouple? It is what keeps the pilot light lit. It is a small tube that runs from the pilot light to the control valve. The tube is made from two types of metal that when heated produce a small electrical current that keeps the gas valve open. Thermocouple goes bad the pilot light goes out and no gas can get into the house.
What if you changed the gas control valve and the electronic ignition on the water heater and the pilot still goes out after awhile?
The thermocouple is usually the first thing to change. It controls the valve and the spark ignition is just to light the pilot.
What is the function of a heater thermocouple in a heating system?
A heater thermocouple is a safety device that detects if the pilot light in a heating system is lit. If the pilot light goes out, the thermocouple shuts off the gas supply to prevent a dangerous gas leak.
If the warm manning gas heater pilot will light but goes out before the blower comes on what is wrong?
thermocouple is bad.
