If it senses that the pilot light is not working, it will switch off the gas supply. If the device gets bent away from the pilot light’s flame, it can malfunction over time.

What causes a water heater to keep turning off?
The most likely cause of your gas water heating problem is the thermocouple. Gas can be flow to the burner when the pilot light is on. A faulty thermocouple will cause the burner and pilot to stop working.
How do I know if my thermocouple is broken?
When the probe is sure to get hot, place one lead on the shaft of the thermocouple and the other lead on the connector. The thermocouple needs to be replaced for the reading to be less than 25 milivolts.
Can you clean a thermocouple?
It is possible to clean a thermocouple, but you have to do it with a light touch. Use a steel wool or emery cloth to lightly clean the tip of the thermocouple to remove any build up. Cleaning a thermocouple is not a solution to an issue.
How do you clean a thermocouple on a water heater?
There is a way to gently clean the end of the thermocouple. If there is a power wire connecting to the thermocouple terminal, you need to clean it off. It is possible to detach the thermocouple from the burner assembly to clean it.
Why does my gas heater turn off by itself?
If the furnace air filter is dirty, it will block the flow of air to the exchanger. The furnace will be shut off if the heat exchanger gets too hot.
How much does it cost to replace a thermocouple?
A worn-out thermocouple is one of the causes of pilot lights not staying lit. A new one costs $5 to$10. It is easier to remove the whole burner and thermocouple assembly from the water heater than it is to unfasten it.
Can you bypass thermocouple?
You can reach in and unclip the thermocouple from the holding brackets where it meets the pilot light, even if you’ve disabled it. Most of the time it will be held on with a gravity clip, but a small screwdriver is needed to remove the screw.
Why does the pilot light on my gas heater keep going out?
If there is a fault in the furnace, you will be very uncomfortable. If the gas furnace’s pilot light doesn’t come on, it could be due to a weak flame, faulty thermocouple, or a problem with the gas regulator.
