What Does the Blinking Light on My Heating System Mean?
Your heating system depends on lights to flash code when it needs to be repaired. It also uses this system to tell you it’s running properly.
Regular operation includes:
- Both lights flash slowly—heater running correctly.
- Both lights flash fast—heater is initiating the call for heat.
If you notice a solitary light blinking slowly and the other going on and off fast, your heating system could be having a low flame signal. This can occur even when your furnace is heating correctly. It signifies the flame sensing rod might have build-up or in the bad spot on the burner. Reach out to us at 309-323-9584 for help.
