What Does the Blinking Light on My Heater Mean?
Your furnace uses lights to flash code when it needs to be repaired. It also works this system to tell you it’s working like it should.
Correct operation includes:
- Simultaneous slow flash—heater heating correctly.
- Both lights flash fast—heater is initiating the call for heat.
If you see one light flashing slowly and the other blinking fast, your heating system might have a low flame signal. This can take place even when your heating system is operating properly. It indicates the flame sensing rod may have build-up or in the bad spot on the burner. Contact us at 301-960-3247 for support.
