Pilot light is a safety item; to light the pilot, you need to heat up an internal thermocouple; When hot enough, thermocouple will hold open the gas valve on pilot light.
If the pilot shuts off when you release the "button", either
(1) you did not hold it in long enough & heat up thermocouple sufficiently -OR-
(2) the thermocouple has gone bad.
Replacements are standardized, easy to find, and well under $10 each, but, sometimes difficult to install.

How does Pilot-Operated Check Valve work?
A pilot-operated check valve allows fluid to flow in one direction while preventing backflow, using a pilot mechanism to control the valve's operation. When fluid flows in the forward direction, it lifts a pilot piston, which opens the main valve and allows flow. If there’s a reverse flow or pressure drop, the pilot piston closes, sealing the valve and preventing backflow. This design ensures reliable operation even under varying pressure conditions, making it suitable for hydraulic systems.
How does Pilot Operated Check Valve work?
A pilot operated check valve allows fluid to flow in one direction while preventing backflow, but it also includes a pilot mechanism that enables it to open under specific conditions. When the pressure on the inlet side exceeds the pressure on the outlet side, the check valve opens to allow flow. If backflow occurs, the pilot mechanism closes the valve to prevent reverse flow, ensuring system integrity. This design is particularly useful in hydraulic systems where maintaining pressure and preventing reverse flow is critical.
Why is the pilot light not staying lit?
The pilot light may not be staying lit due to a dirty or damaged thermocouple, a faulty gas valve, or insufficient gas flow.
How does a thermocouple pilot light work in a gas appliance?
A thermocouple pilot light works by generating a small electric current when heated by the pilot flame in a gas appliance. This current keeps a valve open to allow gas to flow, maintaining the pilot light. If the pilot light goes out, the thermocouple cools down, causing the valve to close and prevent gas leaks.
What does a pilot light do on a heater?
it heats up the thermo couple which opens up the gas control valve allowing gas to flow to the main burner. if the pilot goes out the thrmo couple will cool and shut the gas valve so gas does not come out
What causes a pilot light to go out in a gas appliance?
A pilot light in a gas appliance can go out due to issues such as a draft, a dirty or faulty pilot light component, or a lack of gas flow.
What would prevent a pilot from lighting at all on a gas water heater?
If a pilot light on a gas water heater fails to ignite, it could be due to a defective thermocouple, clogged pilot tube, insufficient gas flow, or a malfunctioning gas control valve. It is important to have a professional technician diagnose and fix the issue to ensure safe and reliable operation of the water heater.
How do you change the egr valve on a 2003 Honda Pilot?
With hondas always clean the valve and passages before replacing the valve it is probably just carbon build up restricting flow and throwing a code. This is a very common problem.
What is pilot valve in fuel oil purifier?
A pilot valve in a fuel oil purifier is a crucial component that regulates the flow of fuel oil through the purification system. It controls the operation of the purifier by adjusting the pressure and flow rates, ensuring optimal separation of contaminants from the fuel. By managing the hydraulic pressure, the pilot valve helps maintain the efficiency of the purification process and protects the main components of the system from potential damage. Its precise functioning is essential for achieving the desired fuel quality and operational reliability.
Pilot lite on teledyne laars mini therm 2 wont stay lit?
Replacing the thermocouple that the pilot flame touches when it is lit will fix the problem 90% of the time. A thermocouple costs about ten dollars and allows the gas to the pilot and main tube to flow by generating millivolts from the heat of the pilot flame. The thermocouple is a copper wire attached by a small nut to the main gas valve near the pilot tube coming out of the gas valve.
How does a generators produce electricity?
. This causes electrons to move through the conductor, which is creates a flow of electricity that we can use for lighting or running our computers.
How is fuel supplied to the pilot assembly on a gas furnace?
In a gas furnace, fuel is supplied to the pilot assembly through a gas line that connects to the gas valve. When the thermostat calls for heat, the gas valve opens, allowing gas to flow to the pilot assembly. The pilot, which is a small flame, ignites the gas, creating a flame that can then light the main burners when the furnace is operating. This process ensures that the furnace operates efficiently and safely.
