What Does the Flashing Light on My Heating System Mean?
Your furnace relies on lights to flash code when it requires repairs. It also engages these lights to let you know it’s operating properly.
Normal heating consists of:
- Concurrent slow flash—heater heating correctly.
- Both lights flash fast—heater is beginning to call for heat.
If you realize that a lone light flashing 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 heater is heating like it should. It signifies the flame sensing rod could be dirty or in the wrong area on the burner. Contact us at 631-246-4029 for help.
