What Does the Flashing Light on My Furnace Mean?
Your heating system depends on lights to flash code when it is malfunctioning. It also works this system to tell you it’s working correctly.
Normal operation consists of:
- Simultaneous slow flash—furnace operating correctly.
- Both lights flash fast—heater is beginning to call for heat.
If you see a lone light blinking slowly and the other blinking fast, your heating system might be experiencing a low flame signal. This can occur even when your heater is working correctly. It signifies the flame sensing rod might need to be cleaned or in the incorrect area on the burner. Call us at 512-937-2001 for help.
