What Does the Flashing Light on My Heater Mean?
Your heater depends on lights to flash code when it requires repairs. It also works this system to let you know it’s heating like it should.
Normal function includes:
- Simultaneous slow flash—furnace operating properly.
- Concurrent fast flash—furnace is starting to call for heat.
If you realize that a single light blinking slowly and the other flashing rapidly, your heating system could be experiencing a low flame signal. This can occur even when your furnace is heating correctly. It means the flame sensing rod might have buildup or in the wrong location on the burner. Call us at 512-937-2001 for assistance.
Here are a few other of the most routine problems for Lennox furnaces.
