What Does the Flickering Light on My Heater Mean?

Your furnace depends on lights to flash code when it is malfunctioning. It also engages these lights to let you know it’s heating like it should.

Normal function consists of:

  • Concurrent slow flash—heating system operating like it should.
  • Simultaneous fast flash—furnace is beginning to call for heat.

If you realize that a solitary light flashing slowly and the other flashing fast, your heating system may have a low flame signal. This can happen even when your heater is running properly. It means the flame sensing rod may need to be cleaned or in the bad spot on the burner. Call us at 778-693-2532 for help.

Here are some of the most routine faults for Lennox furnaces.
