Its control panel has twin LED lights that can display a fault code. Subject to the failure, your heating system could show continuous or flashing lights.

What Does the Flickering Light on My Heating System Mean?

Your heating system depends on lights to flash code when it is malfunctioning. It also uses this system to tell you it’s working correctly.

Normal heating involves:

  • Simultaneous slow flash—furnace working properly.
  • Both lights flash fast—heating system is starting to call for heat.

If you notice a solitary light blinking slowly and the other going on and off quickly, your heater may be having a low flame signal. This can take place even when your heating system is operating properly. It indicates the flame sensing rod could need to be cleaned or in the bad area on the burner. Call us at 715-318-6728 for assistance.

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

Heating System Will Not Turn On

  1. Both LED lights aren’t lit. This signifies your heater might not have power. Find the breaker box to ensure the heater fuse has not triggered. Try resetting the fuse if it’s in the “off” area. If it instantly turns off after you reset it, don’t touch the breaker and contact us at 715-318-6728.
