While your Lennox® furnace cannot speak to you, it possesses a method to tell you about a furnace error.

Its control board has a set of LED lights that can share a fault code. Depending on the malfunction, your furnace might display solid or flashing lights.

Though there are a few elementary furnace fixes you can finish on your own, the majority of fixes are best left to experts. When your furnace won’t start or give warmth, get in touch with I-Deal HVAC at 505-317-9598 for experienced furnace repair in Albuquerque.

Our experts will rapidly determine and repair the problem, even if you don’t own a Lennox heating system. We can repair any brands or models—and get the warmth returned to your home fast.

What Does the Flickering Light on My Furnace Mean?

Your heating system uses lights to flash code when it is malfunctioning. It also uses this setup to let you know it’s heating like it should.

Normal operation involves:

  • Simultaneous slow flash—furnace running like it should.
  • Simultaneous fast flash—furnace is starting to call for heat.

If you notice a single light blinking slowly and the other going on and off fast, your furnace might be having a low flame signal. This can happen even when your furnace is operating correctly. It indicates the flame sensing rod might be dirty or in the incorrect location on the burner. Contact us at 505-317-9598 for help.

Here are some of the most routine problems for Lennox furnaces.

Heater Will Not Turn On

Here are a few of the light patterns you could observe when your heater will not or keep running. The bulk of these issues have to be taken care of by a specialist, like one from I-Deal HVAC.

  1. The pair of LED lights are extinguished. This means your heater might not be receiving power. Examine the breaker box to make sure the heater fuse hasn’t flipped. Attempt to reset the fuse if it is in the “off” area. If it instantly trips following a reset, don’t try to reset it again and contact us at 505-317-9598.
  2. An individual light is continuous and the other is flashing slowly. This shows the flame rollout switch is likely open. The part is an essential safety guard that aids in preventing fires and carbon monoxide. You shouldn’t try to fix this issue on your own.
  3. An individual light is flickering rapidly and the other is blinking slowly. This often indicates power polarity has been inverted. Your heating system could have a wiring error that calls for professional aid from I-Deal HVAC.
  4. The pair of lights are blinking slowly. This signifies your heating system’s blower motor likely isn’t working. This piece sends hot air from the furnace into your home. We can assist in figuring out what’s wrong with this component.
  5. A single light is flashing slowly and the other is flashing quickly. This means your heater might have insufficient voltage or a short circuit. Reach out to our specialists at 505-317-9598 for help.
  6. One light is blinking on, on, off while the other blinks on, off, on. This signifies there might be an issue with your heating system’s motherboard or wiring. I-Deal HVAC can pinpoint the problem and fix it.
  7. Both lights are using alternate slow blinks. This signifies your HVAC equipment likely has a flame failure. There may be an issue with its gas supply, gas valve or ignitor control. Get in touch with us at 505-317-9598 for assistance.
  8. A single light blinks slowly while the other remains solid. This often means your heating system’s limit switch is malfunctioning. The switch stops your HVAC equipment from overheating. Call the pros at I-Deal HVAC for help.

Heating System Blower Runs But No Warm Air

Here’s what may be at fault when you observe your heating equipment’s blower fan working, but you aren’t getting any heated air.

  • The pair of lights display alternate fast blinks. This indicates your furnace ignitor might not be in working order. This piece lights energy in your heater to produce warm air and should be serviced by a technician from I-Deal HVAC.
