While your Lennox® heater isn’t able to talk to you, it has a method to tell you about a furnace error.

Its control panel has double LED lights that can display a fault code. Depending on the problem, your heating system may display continuous or flashing lights.

Though there are certain simple heating repairs you can take care of yourself, most fixes are best left to HVAC technicians. When your furnace will not kick on or put out warm air, call JTech Mechanical at 281-231-8768 for skilled furnace repair in Magnolia.

Our specialists will rapidly detect and repair the breakdown, even if you don’t use a Lennox heating system. We can fix whichever types or makes—and get the warmth reintroduced to your residence fast.

What Does the Flickering Light on My Furnace Mean?

Your heating system depends on lights to flash code when it isn’t working right. It also uses these lights to relay it’s working like it should.

Regular operation involves:

  • Concurrent slow flash—heating system operating properly.
  • Both lights flash fast—furnace is starting to call for heat.

If you see a solitary light blinking slowly and the other blinking quickly, your heater might be having a low flame signal. This can occur even when your heating system is heating correctly. It indicates the flame sensing rod might have buildup or in the bad spot on the burner. Contact us at 281-231-8768 for help.

Here are several other of the most common errors for Lennox HVAC systems.

Furnace Will Not Start

Here are some of the light sequences you may see when your heating system won’t turn on or keep heating. The bulk of these problems need to be taken care of by a specialist, such as one from JTech Mechanical.

  1. The duo of LED lights aren’t lit. This indicates your HVAC system might not be receiving power. Go to the breaker box to make sure the heater fuse isn’t triggered. Attempt to reset the fuse if it’s in the “off” area. If it immediately flips after a subsequent reset, don’t touch the breaker and get in touch with us us at 281-231-8768.
  2. One light is unchanging and the other is flickering slowly. This shows the flame rollout switch is may be not working right. The part is a critical safety tool that helps in stopping fires and carbon monoxide. You shouldn’t try to repair this issue on your own.
  3. An individual light is blinking quickly and the other is flickering slowly. This typically indicates power polarity has been transposed. Your heating system could have a wiring error that requires expert aid from JTech Mechanical.
  4. The duo of lights are flashing slowly. This means your furnace’s blower motor probably isn’t working. This part distributes hot air from the HVAC system into your residence. We can assist in determining what’s causing a problem with this part.
  5. An individual light is flickering slowly and the other is flickering fast. This means your heating system might have low voltage or a short circuit. Contact our experts at 281-231-8768 for assistance.
  6. One light is flickering on, on, off while the other blinks on, off, on. This signifies there may be trouble with your HVAC system’s control panel or wiring. JTech Mechanical can find the fault and repair it.
  7. Both lights display alternating slow flickers. This means your heating system may have a flame error. There may be an issue with its gas supply, gas valve or ignitor control. Reach out to us at 281-231-8768 for support.
  8. A single light flashes slowly while the other stays solid. This often indicates your HVAC equipment’s limit switch is experiencing an error. The switch prevents your heater from getting too hot. Get in touch with the pros at JTech Mechanical for help.
