What Does the Blinking Light on My Heater Mean?

Your heating system depends on lights to flash code when it isn’t working right. It also uses this setup to relay it’s working properly.

Correct function consists of:

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

If you notice a lone light blinking slowly and the other going on and off fast, your heating system may have a low flame signal. This can take place even when your furnace is working correctly. It indicates the flame sensing rod may have buildup or in the incorrect area on the burner. Call us at 724-401-1843 for support.

Here are some of the most common problems for Lennox heaters.
