Signs of a Malfunctioning Furnace Burner

A malfunctioning furnace burner can cause unreliable and unsafe heating. To ensure your household’s heat works well throughout winter, heating repair experts in Dacula, GA, want you to keep an eye out for the following signs of failure and call for repairs right away.

Discolored Flames

A working furnace should always produce a blue, steady flame. If the flame turns yellow and flickers, this is a clear sign that the burners are having difficulty reaching proper combustion. Dirt buildup and mechanical issues are two reasons this happens. You must have the burners cleaned or repaired ASAP to prevent excess carbon monoxide production.

Poor Heating Performance

Have you experienced any of the following heating performance issues?

• Inconsistent heating
• Frequent cycling
• Intermittent shutdowns
• Cold spots
• Sudden rise in heating costs

These are all signs pointing to malfunctioning furnace burners. Sometimes, maintenance services like cleaning can correct these problems. However, if the burner issue is serious, the unit may require repair or replacement services.

Weird Sounds

When your furnace turns on, it makes some noise during the ignition period. The sounds you want to stay alert for are unusual and uncharacteristically loud. If you hear a loud bang or pop, this is called delay ignition and happens when gas builds up in the system. The pop you hear is a mini explosion and happens when burners are dirty or faulty. Delayed ignition isn’t something to ignore because it can lead to heat exchanger damage and more dangerous situations.

If you believe your furnace has ignition problems, don’t wait to contact heating repair experts.
