Pilot Light
What is a pilot light?
A pilot light consists of a series of components that combust a fuel source. When they burn, the light will ignite. In many cases, this will result in a spark. You can learn more about this component in the text below. Here are some things to keep in mind about a pilot light. If you have trouble understanding it, contact a professional.
Problems with a Standing Pilot Light:
The most common problem with a standing pilot light is that the flame goes out. The naked flame is susceptible to sudden drafts and air currents. Fortunately, most heaters have an ignition system to relight the pilot light, but other problems can also arise. Some of the most common problems associated with a standing pilot light are listed below. Here’s what to do if you experience these problems:
Defect in Gas Valve:
The gas valve may be defective. v To check for leaks, use soap solution and an explosive gas detector. If none of these options work, replace the pilot assembly. If the problem persists, repeat the process. Then, check the thermocouple. If the pilot light continues to be yellow, the gas level is too high.
Inefficient combustion can also cause a yellow flame. This occurs when the gas-to-air mixture is not efficient enough to produce adequate heat. The gas can cause carbon monoxide poisoning. When this happens, symptoms of CO poisoning include headaches, fatigue, and nausea. Drafts or a furnace cover may cause inefficient combustion. A professional furnace cleaner can restore the flame and prevent a dangerous problem from affecting your safety.
Reasons for Problems:
In addition to these problems, the gas supply may be disrupted for several reasons. Some construction activities result in gas supply interruption. If this is the case, the gas company should contact you immediately. To ensure your gas supply is stable, you may want to check with your neighbors and call your utility company. A qualified HVAC technician can conduct a series of troubleshooting procedures to solve your pilot light issue.
A standing pilot light is the traditional ignition device for most natural gas-burning furnaces. This small gas flame is located at the bottom of the stove and is frequently lit by a green light bulb. You can see the green flicker that illuminates the pilot flame. If this does not work, you may need to repair the furnace or contact a technician. Then, you can begin to use the heating system again.
Intermittent Pilot Ignition System:
An intermittent pilot ignition system works by opening a pilot valve and providing a continuous spark to the electrode in the main burner. This spark ignites the pilot burner gas and produces a flame. When the pilot flame is extinguished, the sensor detects it and signals the intermittent pilot ignition control to discontinue the spark and open the main gas valve. This way, the pilot flame remains constant, even though the main valve may be closed.
Associated Problems with the Intermittent Pilot Ignition System:
Various factors may cause the problem of an intermittent pilot ignition system. The most common cause is a malfunctioning spark plug, which may not work correctly. Another problem is a cracked ignition module. These ignition systems operate as quickly as possible.However, if the spark plug is faulty, the ignition system may start with a “bang” instead of an intermittent flame. If this is the case, the system may not properly function, and it can lead to dangerous levels of gas in the engine. A certified technician can troubleshoot the problem quickly and accurately.
Causes of Problems with the Intermittent Pilot Ignition System:
If you are experiencing any problems with your system, contact your Salt Lake City heating contractor to see the solutions. An intermittent pilot ignition system is more complex than a continuous one and may cost more to fix. Design Comfort, a company that provides heating services in Salt Lake City, Utah, can help you with your furnace and boiler needs. Our heating service technicians are trained to handle all kinds of emergencies, including emergencies.
Other common causes of an intermittent pilot ignition system include dirt and a blocked gas line. Dirty pilot openings can prevent the flame from reaching the thermocouple, which is what ignites the gas. The inefficient flame may also trigger the safety mechanism and shut off the gas. Eventually, it will cause an explosion and could cause a fire. By replacing the gas supply, the system problems, including carbon monoxide poisoning are avoided.
Thermocouple:
A thermocouple sends a small electrical current when it detects a temperature change. It connects two dissimilar metals that form a measurement junction. When one metal heats, the other cools. This results in a voltage, which tells the gas valve to open or close. The voltage generated by a thermocouple can cause a gas valve to open or close based on its temperature.
Thermocouples are a small component and may not be noticeable to the naked eye. However, you may have a gas leak if you can smell gas or hear a hissing noise. In any case, contact a professional to have it checked out. Cleaning the thermocouple can help solve the problem and extend its life. If you’re unsure, you can follow the steps outlined below.
Problems with a Thermocouple:
A broken or dirty thermocouple may cause a problem with a pilot light. This problem is easily fixed by cleaning it with fine-grade sandpaper and relighting the pilot light. If the problem continues, you should replace the thermocouple, which is a time-consuming and potentially hazardous task. A broken thermocouple can also result from gas flow issues, so if the pilot light is flickering or weak, the problem could be related to the thermocouple.
First, you need to check the pilot flame. If it is too large, a broken thermocouple will not detect the flame accurately. Also, a dirty thermocouple will not trigger the safety device. Upon detection of burning flame, it shut down the valve . So, check the pilot flame before replacing the thermocouple. In some cases, you can return the pilot light thermocouple yourself. You can also hire a heating system repair professional to do this job for you.
Recommendations:
Contact a professional immediately if your pilot flame won’t stay lit. Don’t mess with the gas line. If you can’t light it, first unthread the threaded connection from the gas line. Then remove the copper lead and nut. Next, remove the thermocouple mounting bracket. Then, position the steel tube up, and the copper lead down.
Alternatives to a Standing Pilot Light:
A standing pilot light is a traditional ignition source for natural gas-fueled combustion heating systems. It consists of a small burner, a gas valve, and a thermocouple that registers the heat generated by the pilot light. Upon detection of heat, the gas valve remains open, preventing the home from filling with gas. However, there are some alternatives to a standing pilot light. Here are some of them.
Extinguishing an inactive pilot light is another way to save energy. This practice not only cuts down on fuel consumption but also reduces fire risk. Alternatively, homeowners can purchase appliances that don’t have a pilot light or get an inspection by a professional. If there are concerns about the condition of fuel-burning appliances, contact InterNACHI for it fixing. They will answer any questions you might have about their operation.
Gas Stoves:
Gas stoves also have a standby mode. You should check your gas supply if the standing pilot flame does not burn. It may be insufficient. In that case, you can try cooking with a gas stove. You can call your utility company if the gas supply is still adequate. In addition, gas stoves may also check for gas supply. In case the supply is limited, contact the utility company to find out why you can’t use the stove.
Solutions to Overcome Problems Associated with Standing Pilot Light:
A standing pilot light also wastes a significant amount of fuel. Operating a typical gas heater costs about $18 or so a month. If the pilot light is continuously on, it consumes approximately 600 BTUs of gas. That’s about 14400 BTUs per hour, equivalent to nearly five gallons of gas per year. And the constant heat generated by a standing pilot light increases your air conditioning load.
In addition to preventing moisture from damaging your heating system, a continuous pilot light reduces the maintenance and repair costs associated with chimneys. Mercaptan, a chemical additive in natural gas, has an odor that attracts spiders. When the chimney is clogged with spider webs, these spiders can cause serious problems. A continuous pilot light reduces wear and tear on your unit and never leaves you wondering whether your team will start.
