Why Does the Pilot Light Go Out?
The pilot light, also known as the igniter or pilot flame, is a small flame that burns continuously in a variety of appliances, including gas stoves, water heaters, and furnaces. While the pilot light is designed to be a constant, steady flame, it’s not uncommon for it to go out from time to time. But what causes the pilot light to extinguish? In this article, we’ll explore the reasons why the pilot light may go out, as well as some common troubleshooting techniques to get it working again.
Faulty Pilot Assembly
Cause: A faulty pilot assembly is one of the most common reasons why the pilot light goes out.
- Symptoms: A faulty pilot assembly can cause the pilot light to burn irregularly, producing a small, flickering flame or no flame at all.
- Solution: If you suspect that the pilot assembly is faulty, you may need to replace it. Always follow the manufacturer’s instructions for replacement.
Gas Leak
Cause: A gas leak in the appliance or the supply line can cause the pilot light to go out.
- Symptoms: If you suspect a gas leak, you may notice hissing sounds, smells, or a lack of odor.
- Solution: If you suspect a gas leak, DO NOT TRY TO RELIGHT THE PILOT LIGHT. Instead, turn off the gas supply to the appliance and contact a qualified plumber or gas technician.
Blockages or Dirty Igniter
Cause: Blockages or debris buildup in the igniter can prevent the pilot light from staying lit.
- Symptoms: If the igniter is dirty or clogged, you may notice that the pilot light is difficult to light or refuses to stay lit.
- Solution: Try cleaning the igniter and surrounding area with a cloth or brush. If the blockage is more severe, you may need to use a more advanced cleaning tool or contact a professional.
Pilot Light Too Low
Cause: If the pilot light is too low, it can be extinguished by wind or air circulation.
- Symptoms: If the pilot light is too low, you may notice that it blows out or flickers when the air conditioning or ventilation is on.
- Solution: Adjust the pilot light so that it is positioned at a comfortable distance from any air circulation vents.
Incorrect Pilot Light Flame Size
Cause: If the pilot light flame is too small, it can be extinguished by the wind or air circulation.
- Symptoms: If the pilot light flame is too small, you may notice that it refuses to stay lit or flickers constantly.
- Solution: Adjust the pilot light flame size according to the manufacturer’s instructions. DO NOT FORCE THE FLAME as this can cause further problems.
Temperature Changes
Cause: Extreme temperature changes can cause the pilot light to go out.
- Symptoms: If the temperature changes dramatically, you may notice that the pilot light extinguishes or refuses to stay lit.
- Solution: Keep the appliance and surrounding area at a stable temperature. AVOID OVERCROWDING OR OBSTRUCTING AIRFLOW.
Regular Maintenance
Cause: Neglecting regular maintenance can cause the pilot light to go out.
- Symptoms: Failure to clean and inspect the appliance regularly can lead to malfunctions and pilot light extinction.
- Solution: Regularly inspect and clean the appliance according to the manufacturer’s instructions.
Conclusion
The pilot light going out is a common problem that can be caused by a variety of factors, including faulty pilot assemblies, gas leaks, blockages, and more. By understanding the causes of pilot light extinction, you can take steps to prevent it from happening and get your appliance working properly again. Remember to follow the manufacturer’s instructions and take necessary precautions when working with gas appliances. REGULAR MAINTENANCE IS KEY TO AVOIDING PILOT LIGHT PROBLEMS.
