While your Lennox® HVAC equipment can’t chat with you, it does have a method to communicate a furnace error.

Its control panel has twin LED lights that can display a fault code. Based on the problem, your furnace might show continuous or flashing lights.

Though there are various simple HVAC fixes you can finish yourself, many repairs are best left to experts. When your heating system refuses to start or give warm air, reach out to Redhawk Heating & Air Conditioning at 432-237-0168 for expert furnace repair in Odessa.

Our experts will quickly detect and take care of the breakdown, even if you don’t have a Lennox heating system. We can fix all brands or makes—and get the warmth reintroduced to your home quickly.

What Does the Flashing Light on My Furnace Mean?

Your heater uses lights to flash code when it requires repairs. It also engages this setup to tell you it’s working like it should.

Normal heating involves:

  • Concurrent slow flash—heating system heating properly.
  • Simultaneous fast flash—heating system is starting to call for heat.

If you see a single light flashing slowly and the other blinking quickly, your furnace might have a low flame signal. This can occur even when your furnace is heating properly. It means the flame sensing rod may need to be cleaned or in the wrong spot on the burner. Reach out to us at 432-237-0168 for assistance.

Here are a few other of the most common problems for Lennox heating systems.

Heating System Won’t Kick On

Here are a few of the light patterns you could notice when your heat will not or keep operating. The bulk of these errors must be taken care of by a specialist, for instance from Redhawk Heating & Air Conditioning.

  1. All LED lights are off. This indicates your heater might not be receiving power. Examine the breaker box to confirm the furnace fuse hasn’t tripped. Attempt to reset the fuse if it’s in the “off” spot. If it rapidly turns off following a reset, don’t try to reset it again and contact us at 432-237-0168.
  2. A single light is continuous and the other is blinking slowly. This shows the flame rollout switch is likely malfunctioning. The part is a critical safety tool that helps in stopping fires and carbon monoxide. You shouldn’t attempt to fix this fault on your own.
  3. One light is blinking quickly and the other is blinking slowly. This typically means power polarity has been reversed. Your furnace might have a wiring fault that calls for professional help from Redhawk Heating & Air Conditioning.
  4. The pair of lights are flashing slowly. This means your furnace’s blower motor probably isn’t operating. This piece sends heated air from the furnace into your space. We can aid in pinpointing what’s causing a problem with this component.
  5. One light is blinking slowly and the other is blinking fast. This means your HVAC system might have not enough voltage or a short circuit. Call our specialists at 432-237-0168 for support.
  6. One light is flashing 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. Redhawk Heating & Air Conditioning can determine the fault and repair it.
  7. The pair of lights display alternating slow flickers. This indicates your heating system may have a flame problem. There might be a problem with its gas supply, gas valve or ignitor control. Reach out to us at 432-237-0168 for assistance.
  8. An individual light flickers slowly while the other remains solid. This often indicates your heating system’s limit switch is experiencing an error. The switch prevents your HVAC equipment from becoming too warm. Reach out to the specialists at Redhawk Heating & Air Conditioning for help.

Heater Blower Works But No Heat

Here’s what might be wrong when you notice your heater’s blower fan running, but you aren’t getting any warm air.

  • The pair of lights are giving every other quick blinks. This signifies your furnace ignitor may not be in working order. This piece kindles energy in your heating system to create warm air and should be fixed by an expert from Redhawk Heating & Air Conditioning.
