Pilot Light Problems: Keeping Your Gas Furnace Running Smoothly

Is your home feeling colder than it should? If your gas furnace in West Milford, NJ has unexpectedly stopped working, the problem could be as simple as a pilot light that’s gone out. This is a frequent issue with older gas furnaces, as newer models often rely on advanced electronic ignitions instead of traditional pilot lights.

Don’t worry—the West Milford HVAC experts at Mark Lindsay and Son Plumbing & Heating are here to help! So let’s dive into why this happens and what you can do to get your furnace back up and running, keeping your home cozy and warm.

Common Causes of Pilot Light Failure

Weak or Incorrect Flame

A properly functioning pilot light burns bright blue, which indicates the right mix of gas and air. If your pilot flame is yellow or weak, it could signal a gas leak or other system issues. In such cases, your furnace’s safety mechanisms shut off the gas valve, extinguishing the flame to protect you and your home. Solution: If you notice a yellow flame, turn off the system immediately and call a professional for inspection.

Dust and Debris Build-Up

Over time, dust and dirt can accumulate in the pilot light assembly, clogging the intake valve. This restricts airflow, making it hard for the flame to stay lit. Solution: Routine furnace maintenance can help keep the intake valve clean and prevent this issue.

A Faulty Thermocouple

The thermocouple is a safety device that shuts off the gas if it senses the flame has gone out. When it’s damaged or worn, it may fail to detect the pilot light properly, cutting off the gas flow and extinguishing the flame. Solution: Replacing a thermocouple is not a DIY project—contact a trained technician for service.

Strong Drafts or Airflow Issues

A sudden draft can blow out your pilot light, especially if the furnace is in an area prone to wind or air movement. Solution: Locate your furnace’s manual to follow the manufacturer’s instructions for relighting the pilot light. If the flame won’t stay lit after multiple attempts, professional assistance may be needed.

How to Prevent Pilot Light Problems

• Schedule Regular Maintenance: Routine inspections and heating maintenance can help keep your furnace in top shape by identifying issues like dirt build-up or thermocouple wear before they cause a problem.
• Check for Drafts: Ensure your furnace is located away from windows or areas with strong airflow.
• Monitor the Flame: Keep an eye on your pilot light’s color and stability. A consistent blue flame is a good indicator of a healthy system.

When to Call a Professional

If relighting the pilot light doesn’t solve the issue, or if you notice unusual signs like a yellow flame, don’t hesitate to contact an expert. Addressing pilot light problems promptly ensures your furnace operates safely and efficiently throughout the season.
