What Does the Flickering Light on My Heater Mean?

Your heater depends on lights to flash code when it isn’t working right. It also engages this setup to relay it’s operating like it should.

Regular operation includes:

  • Simultaneous slow flash—furnace running properly.
  • Concurrent fast flash—heating system is initiating the call for heat.

If you notice a single light blinking slowly and the other going on and off fast, your furnace could be having a low flame signal. This can happen even when your heating system is running properly. It means the flame sensing rod may be dirty or in the bad spot on the burner. Call us at 949-204-0859 for assistance.

Here are some of the most routine problems for Lennox HVAC systems.
