What Does the Flashing Light on My Heater Mean?

Your heater depends on lights to flash code when it is malfunctioning. It also works this setup to tell you it’s working properly.

Regular function involves:

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

If you see a single light blinking slowly and the other blinking quickly, your heater may be having a low flame signal. This can happen even when your heating system is operating correctly. It means the flame sensing rod could need to be cleaned or in the bad area on the burner. Call us at 530-885-8081 for assistance.

Here are a few other of the most routine faults for Lennox HVAC systems.
