Why is the Pilot Light in My Gas Furnace Always Going Out?
Older gas furnaces in in Deerfield, IL, typically have traditional pilot lights that burn constantly. When your furnace begins a heating cycle, it uses this light to ignite the burners and warm the home. Learn more about why your pilot light may be malfunctioning.
Frequently Blows Out
Pilot lights are easily impacted by the thermocouple and strong drafts. Once they’re out, old-fashioned pilots need manual relighting according to your owner manual’s instructions. If your pilot is repeatedly going out, your system may need expert maintenance to find the internal issue.
Burns Fuel Inefficiently
Your furnace’s pilot light should always burn blue and steadily. If the pilot is flickering or sputtering, it could be struggling to burn its fuel efficiently. Always keep an eye out for orange or yellow flames that indicate natural gas is leaking from somewhere in the system.
One of the most common reasons behind fuel inefficiencies is dirt buildup on the gas intake valve. As dirt and debris cover the valve, they impede the flame’s air supply.
You’ll never have to worry about this issue if you call for professional heating tuneups at least twice a year. A preventive maintenance plan can save you money on your utility bills.
Your pilot light has a safety feature called a thermocouple that detects potential issues. This device can shut off the gas supply to the pilot if it doesn’t sense a flame or knows that fuel isn’t burning efficiently. Unfortunately, the thermocouple can malfunction if it slips out of place or struggles with dirt buildup.
Your furnace needs a well-maintained pilot light to keep your home comfortable throughout the winter. Call our NATE-certified experts at Carefree Comfort Inc. when you need service for your HVAC system in Deerfield, IL.
