What Does the Flashing Light on My Heating System Mean?
Your heater depends on lights to flash code when it requires repairs. It also uses these lights to relay it’s working correctly.
Regular function involves:
- Both lights flash slowly—furnace operating properly.
- Simultaneous fast flash—heater is starting to call for heat.
If you notice a single light going on and off slowly and the other going on and off fast, your heater might be experiencing a low flame signal. This can occur even when your furnace is running correctly. It indicates the flame sensing rod may be dirty or in the wrong area on the burner. Contact us at 775-230-7628 for assistance.
