What Does the Flashing Light on My Heater Mean?
Your furnace uses lights to flash code when it needs to be repaired. It also works this system to relay it’s heating like it should.
Correct heating involves:
- Concurrent slow flash—heating system heating properly.
- Simultaneous fast flash—heater is starting to call for heat.
If you notice a single light flashing slowly and the other going on and off rapidly, your heater might be having a low flame signal. This can occur even when your heating system is heating correctly. It signifies the flame sensing rod may be dirty or in the wrong area on the burner. Contact us at 717-383-4479 for help.
