Knowing what they mean helps homeowners decide if they can resolve the issue themselves or need a technician’s help.

4. Common Causes of a Blinking Yellow Light A reduced gas supply or a malfunctioning gas valve can trigger a warning. This can prevent the furnace from igniting properly. Issues with the ignition system or pilot light are common causes of a yellow light. These problems may prevent the furnace from heating as expected. A faulty thermostat or control board can interfere with furnace signals. This may cause the system to display a blinking yellow light as a warning. Blocked air filters or vents can impact performance. Restricted airflow may trigger alerts to prevent overheating. 1. Low Gas Supply or Gas Valve Issue 2. Ignition or Pilot Light Problems 3. Thermostat or Control Board Malfunction 4. Ventilation Blockages or Airflow Restrictions
5. Basic Troubleshooting Steps Ensure the thermostat is set to "Heat" and the temperature is higher than the current room temperature. Sometimes, simple setting adjustments can resolve the issue. Confirm that the gas valve is open and supplying fuel to the furnace. A closed or partially closed valve can cause the yellow light to blink. Turn off the furnace for a few minutes, then switch it back on. This can reset minor errors in the system and may stop the blinking light. A clogged air filter can restrict airflow, impacting performance. Check and replace the filter if it’s dirty or overdue for a change. 1. Check the Thermostat Settings 2. Inspect the Gas Supply 3.
