What Does the Blinking Light on My Heating System Mean?
Your heater relies on lights to flash code when it requires repairs. It also uses this system to relay it’s running correctly.
Regular operation includes:
- Simultaneous slow flash—heating system running like it should.
- Simultaneous fast flash—furnace is initiating the call for heat.
If you realize that one light flashing slowly and the other flashing rapidly, your heater may be having a low flame signal. This can take place even when your furnace is running correctly. It means the flame sensing rod may be dirty or in the bad location on the burner. Reach out to us at 918-212-8943 for help.
