Its control panel has two LED lights that can display a fault code. Depending on the problem, your heating system could show steady 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 setup to relay it’s working correctly.

Normal function consists of:

  • Concurrent slow flash—heater heating correctly.
  • Simultaneous fast flash—heating system is beginning to call for heat.

If you notice a lone light flashing slowly and the other going on and off quickly, your heater might have a low flame signal. This can happen even when your heater is running properly. It indicates the flame sensing rod might need to be cleaned or in the wrong spot on the burner. Call us at 208-621-0129 for assistance.
