What Does the Blinking Light on My Furnace Mean?
Your heating system relies on lights to flash code when it isn’t working right. It also engages these lights to relay it’s working properly.
Regular operation consists of:
- Simultaneous slow flash—heater operating properly.
- Concurrent fast flash—furnace is initiating the call for heat.
If you see a lone light flashing slowly and the other flashing rapidly, your furnace might have a low flame signal. This can take place even when your furnace is running correctly. It indicates the flame sensing rod might need to be cleaned or in the bad location on the burner. Contact us at 256-801-4701 for assistance.
Here are some of the most typical issues for Lennox furnaces.
