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.

Furnace Will Not Turn On

Here are many of the light patterns you could see when your heater will not or keep heating. Most of these problems must be fixed by a specialist, like one from Tru Air Systems LLC.

  1. Both LED lights are off. This indicates your heater might not have electricity. Go to the breaker box to ensure the heating system fuse hasn’t flipped. Try resetting the fuse if it’s in the “off” position. If it promptly turns off after you reset it, don’t touch the breaker and call us at 505-226-3525.
  2. A single light is stable and the other is blinking slowly. This signifies the flame rollout switch is may be open. The switch is an essential safety guard that assists in stopping fires and carbon monoxide. You shouldn’t try to handle this issue on your own.
  3. A single light is flickering fast and the other is flashing slowly. This often means power polarity has been inverted. Your heating system might have a wiring problem that calls for professional support from Tru Air Systems LLC.
  4. The pair of lights are flashing slowly. This means your heater’s blower motor probably isn’t working. This piece sends heated air from the furnace into your house. We can assist in pinpointing what’s wrong with this part.
  5. An individual light is blinking slowly and the other is blinking rapidly. This indicates your heating system may have insufficient voltage or a short circuit. Contact our technicians at 505-226-3525 for support.
  6. One light is blinking on, on, off while the other flickers on, off, on. This signifies there may be a malfunction with your heater’s control board or wiring. Tru Air Systems LLC can pinpoint the fault and take care of it.
  7. The pair of lights display every other slow flashes. This means your HVAC equipment may have a flame issue. There may be a problem with its gas supply, gas valve or ignitor control. Get in touch with us at 505-226-3525 for help.
  8. An individual light flickers slowly while the other stays steady. This usually indicates your HVAC equipment’s limit switch is malfunctioning. The switch keeps your HVAC equipment from getting too hot. Get in touch with the professionals at Tru Air Systems LLC for assistance.
