What Does the Flashing Light on My Furnace Mean?
Your heater uses lights to flash code when it requires repairs. It also works these lights to relay it’s operating properly.
Correct operation consists of:
- Concurrent slow flash—heater operating like it should.
- Simultaneous fast flash—heater is initiating the call for heat.
If you realize that a lone light blinking slowly and the other flashing quickly, your heater might have a low flame signal. This can take place even when your heating system is operating like it should. It indicates the flame sensing rod could be dirty or in the wrong location on the burner.
