Its control panel has a set of LED lights that can share a fault code. Subject to the problem, your furnace could display continuous or flashing lights.

What Does the Flashing Light on My Heating System Mean?

Your heater relies on lights to flash code when it isn’t working right. It also uses this system to tell you it’s working properly.

Correct function includes:

  • Concurrent slow flash—furnace operating like it should.
  • Both lights flash fast—heater is initiating the call for heat.

If you notice a solitary light going on and off 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 heating system is running correctly. It indicates the flame sensing rod may be dirty or in the incorrect area on the burner. Call us at 360-255-5857 for assistance.

Here are a few other of the most common faults for Lennox heating systems.

Heater Will Not Kick On

Here are many of the light arrangements you may observe when your furnace will not or keep operating. The bulk of these errors have to be handled by a specialist, such as one from Service Max Heating & Air Conditioning.

  1. All LED lights are extinguished. This indicates your heating system might not be receiving power. Find the breaker box to confirm the furnace fuse hasn’t tripped.

  2. An individual light is stable and the other is flickering slowly. This signifies the flame rollout switch is possibly open. The switch is a critical safety device that helps in stopping fires and carbon monoxide. You shouldn’t try to fix this issue on your own.
