What Does the Flickering Light on My Heater Mean?

Your heater depends on lights to flash code when it is malfunctioning. It also works this system to relay it’s working correctly.

Correct heating consists of:

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

If you see a lone light going on and off slowly and the other flashing fast, your heating system might be experiencing a low flame signal. This can occur even when your heater is heating correctly. It means the flame sensing rod may need to be cleaned or in the bad location on the burner. Contact us at 270-358-3167 for assistance.

Here are several other of the most typical issues for Lennox heating systems.

Heater Will Not Turn On

  1. All LED lights are extinguished. This indicates your HVAC system might not have power. Look at the breaker box to ensure the heater fuse has not flipped.
