While your Lennox® heater cannot speak to you, it has a method to get your attention when there’s a furnace error.
Its motherboard has a set of LED lights that can display a fault code. Depending on the problem, your heating system could use solid or flashing lights.
Although there are a few simple furnace adjustments you can complete on your own, many tasks are best taken care of by HVAC technicians. When your furnace won’t kick on or provide heated air, call Tru Air Systems LLC at 505-226-3525 for skilled furnace repair in Albuquerque.
Our technicians will swiftly discover and handle the malfunction, even if you don’t have a Lennox heating system. We can fix any kinds or configuration—and get the warmth reintroduced to your home without delay.
What Does the Blinking Light on My Heater Mean?
Your heater uses lights to flash code when it isn’t working right. It also engages these lights to tell you it’s operating properly.
Correct operation involves:
- Concurrent slow flash—heater working properly.
- Simultaneous fast flash—heater is initiating the call for heat.
If you realize that a single light going on and off slowly and the other blinking rapidly, your heater might be experiencing a low flame signal. This can take place even when your heater is running properly. It signifies the flame sensing rod could need to be cleaned or in the incorrect spot on the burner. Reach out to us at 505-226-3525 for support.
Here are some of the most common faults for Lennox heaters.
