What Does the Blinking Light on My Heating System Mean?

Your heating system depends on lights to flash code when it isn’t working right. It also works this setup to relay it’s heating properly.

Correct function involves:

  • Concurrent slow flash—heating system running correctly.
  • Concurrent fast flash—furnace is beginning to call for heat.

If you see a lone light blinking slowly and the other going on and off quickly, your heating system could have a low flame signal. This can take place even when your furnace is heating properly. It means the flame sensing rod might be dirty or in the incorrect location on the burner. Reach out to us at 309-517-7511 for assistance.

Here are several other of the most routine issues for Lennox heating systems.

Heating System Will Not Start

Here are some of the light arrangements you could see when your heater won’t turn on or keep heating. Most of these problems must be fixed by a specialist, such as one from J.L. Brady Company LLC.

  1. All LED lights aren’t lit. This signifies your heater might not have power. Find the breaker box to make sure the heater fuse isn’t triggered. Try resetting the fuse if it’s in the “off” area. If it instantly turns off following a reset, don’t try to reset it again and get in touch with us us at 309-517-7511.
  2. One light is unchanging and the other is flashing slowly. This implies the flame rollout switch is possibly not working right. The component is an essential safety mechanism that assists in avoiding fires and carbon monoxide. You shouldn’t try to fix this problem yourself.
  3. One light is flashing fast and the other is flashing slowly. This often signifies power polarity has been transposed. Your heating system may have a wiring issue that calls for professional assistance from J.L. Brady Company LLC.
  4. Both lights are flashing slowly. This means your furnace’s blower motor likely isn’t operating. This part distributes hot air from the HVAC system into your rooms. We can help in pinpointing what’s causing an issue with this part.
  5. A single light is blinking slowly and the other is flashing rapidly. This indicates your HVAC system could have not enough voltage or a short circuit. Contact our specialists at 309-517-7511 for support.
  6. One light is flashing on, on, off while the other flashes on, off, on. This indicates there might be trouble with your heater’s control panel or wiring. J.L. Brady Company LLC can determine the error and handle it.
  7. Both lights show alternating slow flashes. This indicates your heating system possibly has a flame error. There could be trouble with its gas supply, gas valve or ignitor control. Reach out to us at 309-517-7511 for assistance.
  8. A single light flickers slowly while the other is solid. This often indicates your heating system’s limit switch is experiencing an error. The switch prevents your HVAC equipment from overheating. Call the experts at J.L. Brady Company LLC for support.

Heating System Blower Works But No Heat
