What Does the Flashing Light on My Heating System Mean?

Your furnace depends on lights to flash code when it isn’t working right. It also uses these lights to relay it’s operating correctly.

Regular function consists of:

  • Simultaneous slow flash—heating system heating like it should.
  • Concurrent fast flash—furnace is initiating the call for heat.

If you notice a single light going on and off slowly and the other flashing rapidly, your heating system could be experiencing a low flame signal. This can take place even when your furnace is operating properly. It indicates the flame sensing rod may have buildup or in the bad location on the burner. Call us at 913-845-9463 for assistance.

Here are a few other of the most typical errors for Lennox heating systems.

Heating System Refuses to Start

Here are many of the light sequences you might notice when your heater won’t turn on or keep heating. The bulk of these problems need to be fixed by a technician, like one from Everest Heating & Cooling.

  1. The duo of LED lights are off. This indicates your HVAC system might not have electricity. Find the breaker box to ensure the furnace fuse isn’t flipped. Attempt to reset the fuse if it is in the “off” area. If it immediately flips after you reset it, don’t touch the breaker and call us at 913-845-9463.
  2. An individual light is stable and the other is blinking slowly. This signifies the flame rollout switch is possibly malfunctioning. The part is an essential safety mechanism that assists in avoiding fires and carbon monoxide. You shouldn’t attempt to handle this problem on your own.
  3. An individual light is blinking rapidly and the other is blinking slowly. This often means power polarity has been reversed. Your heater could have a wiring issue that requires expert support from Everest Heating & Cooling.
  4. Both lights are flickering slowly. This signifies your furnace’s blower motor likely isn’t running. This part circulates heated air from the HVAC system into your space. We can help in pinpointing what’s wrong with this component.
  5. An individual light is blinking slowly and the other is flickering quickly. This indicates your HVAC system might have insufficient voltage or a short circuit. Contact our experts at 913-845-9463 for help.
