What Does the Blinking Light on My Heating System Mean?
Your heating system depends on lights to flash code when it is malfunctioning. It also works this system to let you know it’s heating properly.
Correct operation includes:
- Concurrent slow flash—heater running properly.
- Simultaneous fast flash—furnace is initiating the call for heat.
If you see a single light blinking slowly and the other blinking fast, your furnace might be having a low flame signal. This can happen even when your furnace is operating like it should. It means the flame sensing rod might have buildup or in the bad spot on the burner. Call us at 309-323-9584 for support.
Here are some of the most common problems for Lennox heating systems.
