If you’re having trouble with your pilot light not igniting, you’re not alone. Many homeowners have had this problem before, and it can be frustrating to figure out why your pilot light is lit but your burners won’t ignite.
Fortunately, there are many troubleshooting techniques you can use to identify the source of the problem and get your burners running again.
In this blog post, we’ll discuss the troubleshooting process, identify the source of your ignition problem, and provide tips to keep your pilot light lit and burners burning.
With these simple tips, you’ll be able to get your pilot light lit and burners burning in no time.
What Is Pilot Light?
A pilot light is a small flame that serves as an ignition source for a larger burner or heating element. It is commonly found in gas-powered appliances such as stoves, water heaters, and furnaces.
The pilot light is created by a small flow of gas that is ignited by a spark or electric current. Once lit, the pilot light burns continuously, providing a stable flame that can be used to ignite the larger burner or heating element when needed.
In addition to providing an ignition source, the pilot light also serves as a safety feature in a appliances that run on natural gas. If the pilot light goes out, it can indicate a problem with the gas supply or other components of the appliance.
Some appliances also have automatic shut-off features that are triggered when the pilot light goes out, preventing the buildup of gas that could lead to a dangerous situation.
While pilot lights were once a common feature in gas-powered appliances, they are becoming less common as newer technologies such as electronic ignition systems and hot surface igniters are developed.
These newer technologies are often more energy-efficient and reliable than pilot lights, which can be prone to going out or consuming extra gas even when not in use.
Troubleshooting A Faulty Pilot Light
There are a few easy actions you can take to investigate the problem and get your appliance back up and running if your pilot light isn’t working properly. To find the issue’s root and restart your pilot light, follow the methods listed below.
- Determine the issue’s root cause first. Sometimes, malfunctioning components might contribute to pilot light issues. A broken thermocouple, for instance, can prevent heat from the stovetop from reaching the burner quickly enough to light it. It may be essential to replace that component in this instance, or you might look for other potential problems that could be preventing heat from reaching the burner.
- Then, examine your appliance physically for any problems. Check to see if there isn’t anything blocking the flow of gas to your burner, this obstruction could be the result of a damaged pipe or clogged filters. Moreover, check to see whether your thermocouple or any components downstream from it have been harmed. Last but not least, observe the gas flow for any irregularities. Is it coming in steadily? Is your appliance making any odd noises from beneath it? If so, it may be necessary to replace one or more cooktop parts (such as an igniter).
- After you have checked out any serious problems, use a flame detector to see if your igniter will fire (or lighter). When using an ignition method to start your pilotlight even though everything appears to be in working order mechanically, you could also need to repair one of those parts (igniter included). Last but not least, ensure that there is adequate ventilation so that gas appliance fumes can escape; otherwise, they could pose a health risk to those around. Try relighting your pilot light once everything appears to be in working order and is smelling acceptable; ideally this will address the original problem.
Diagnosing The Problem
Relighting a pilot light can be a simple process, but first, it is important to diagnose the problem that caused it to go out in the first place. Here are the steps to diagnose and relight a pilot light:
Check the gas supply
Make sure the gas supply to the appliance is turned on and there are no leaks in the gas line. If there is a gas leak, turn off the gas supply immediately and contact a professional.
Check the thermocouple
The thermocouple is a safety device that shuts off the gas supply to the appliance if the pilot light goes out. Check that the thermocouple is properly positioned and clean, as a dirty or improperly positioned thermocouple can cause the pilot light to go out.
Check the pilot light
Inspect the pilot light to ensure it is clean and free of debris. Use a soft-bristled brush or compressed air to remove any dirt or debris that may be obstructing the flame. If the pilot light is damaged, it may need to be replaced.
Check the gas valve
The gas valve controls the flow of gas to the pilot light. If the gas valve is closed or malfunctioning, the pilot light will not ignite. Check that the gas valve is in the “on” position and functioning properly.
Light the pilot light
Once you have diagnosed and resolved any issues, it is time to relight the pilot light. Follow the manufacturer’s instructions for your specific appliance, as the process may vary. Typically, the steps involve turning the gas control valve to the “pilot” position, holding down the pilot button or knob, and lighting the pilot light with a lighter or match.
Test the pilot light
After relighting the pilot light, wait a few minutes for the thermocouple to heat up and ensure the pilot light stays lit. If the pilot light goes out again, repeat the diagnosis and relighting process or seek the assistance of a qualified professional.
Inspect The Gas Valve And Igniter
An ignition problem in a gas-powered appliance can be frustrating and potentially dangerous. Here are the steps to identify the source of your ignition problem:
Check the gas supply
Make sure the gas supply to the appliance is turned on and there are no leaks in the gas line. If there is a gas leak, turn off the gas supply immediately and contact a professional.
Inspect the igniter
The igniter is the component that creates the spark or electric current that ignites the gas. Check that the igniter is clean and free of debris. If the igniter is dirty, it may need to be cleaned or replaced.
Check the wiring
Inspect the wiring to the igniter to ensure it is properly connected and not damaged. Loose or damaged wiring can prevent the igniter from working properly.
Check the control module
The control module is the component that controls the timing and function of the igniter. If the control module is malfunctioning, the igniter may not work. Check that the control module is functioning properly and all connections are secure.
Check the gas valve
The gas valve controls the flow of gas to the appliance. If the gas valve is closed or malfunctioning, the igniter will not receive the gas it needs to ignite. Check that the gas valve is in the “on” position and functioning properly.
Check the thermocouple
The thermocouple is a safety device that shuts off the gas supply to the appliance if the pilot light or igniter goes out. Check that the thermocouple is properly positioned and clean, as a dirty or improperly positioned thermocouple can cause the igniter to go out.
Test the igniter
After checking and resolving any issues, it is time to test the igniter. Follow the manufacturer’s instructions for your specific appliance, as the process may vary. Typically, the steps involve turning the appliance on and observing the igniter to ensure it is creating a spark or electric current.
Maintaining And Repairing
Maintaining and repairing is an important aspect of ensuring the safe and efficient operation of your gas appliance. Here are some tips to help you maintain and repair your pilot light system:
Regularly clean the pilot light and surrounding area
Over time, the pilot light can become clogged with dirt, dust, and debris, which can affect its operation. To prevent this, use a soft-bristled brush or compressed air to clean the pilot light and surrounding area at least once a year.
Check for gas leaks
Gas leaks can be dangerous and can occur if the pilot light is not burning properly. To check for gas leaks, use a gas leak detector or a solution of soapy water to test the connection points and pipes around the pilot light. If you detect a gas leak, immediately turn off the gas supply and call a licensed professional to repair it.
Replace the thermocouple
The thermocouple is a safety device that senses the heat from the pilot light and signals the gas valve to open. If the thermocouple is faulty, it can cause the pilot light to go out or prevent the gas valve from opening. To replace the thermocouple, turn off the gas supply and follow the manufacturer’s instructions.
Adjust the pilot light flame
The pilot light flame should be a steady blue flame that is about 1-1/2 inches tall. If the flame is too low or too high, it can cause the pilot light to go out or prevent the gas valve from opening.
Call a licensed professional for major repairs
If you experience major problems with your pilot light system, such as a faulty gas valve or a damaged gas line, it is important to call a licensed professional to make the repairs. Trying to make major repairs yourself can be dangerous and can result in further damage to your gas appliance.
