While your Lennox® heater isn’t able to chat with you, it does have a method to communicate a furnace error.
Its control panel has a set of LED lights that can show a fault code. Subject to the malfunction, your heating system could use continuous or flashing lights.
While there are certain basic heating fixes you can do yourself, many tasks are best taken care of by HVAC technicians. When your heating system refuses to kick on or deliver heated air, contact Northglenn Heating & Air Conditioning at 303-452-4146 for experienced furnace repair in Northglenn.
Our experts will speedily discover and handle the problem, even if you don’t own a Lennox heating system. We can service any brands or configuration—and get the warmth reintroduced to your house quickly.
What Does the Blinking Light on My Heater Mean?
Your heater depends on lights to flash code when it isn’t working right. It also works this system to tell you it’s working correctly.
Regular operation involves:
- Simultaneous slow flash—heater running correctly.
- Simultaneous fast flash—furnace is beginning to call for heat.
If you realize that a single light blinking slowly and the other going on and off rapidly, your heating system may be having a low flame signal. This can occur even when your furnace is running like it should. It indicates the flame sensing rod could have buildup or in the bad spot on the burner. Call us at 303-452-4146 for assistance.
Here are some of the most common faults for Lennox HVAC systems.
