While your Lennox® heating system cannot speak to you, it possesses a way to get your attention when there’s a furnace error.

Its motherboard has two LED lights that can show a fault code. Depending on the malfunction, your heater could show continuous or flashing lights.

While there are some basic furnace adjustments you can complete on your own, the majority of repairs are best taken care of by HVAC technicians. When your heating system will not kick on or provide heat, reach out to Scott Temperature at 785-269-0465 for expert furnace repair in Lawrence.

Our specialists will speedily identify and handle the breakdown, even if you don’t own a Lennox heater. We can fix any types or makes—and get the warmth reintroduced to your home quickly.

What Does the Flickering Light on My Heater Mean?

Your furnace depends on lights to flash code when it requires repairs. It also uses these lights to relay it’s heating like it should.

Correct function consists of:

  • Concurrent slow flash—heater working like it should.
  • Simultaneous fast flash—heating system is initiating the call for heat.

If you realize that a single light going on and off slowly and the other flashing rapidly, your heating system may be having a low flame signal. This can take place even when your heater is working like it should. It signifies the flame sensing rod might need to be cleaned or in the bad spot on the burner. Contact us at 785-269-0465 for help.

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

Furnace Will Not Kick On

Here are some of the light sequences you may observe when your heat refuses to or keep heating. The majority of these issues must be fixed by a professional, like one from Scott Temperature.

  1. All LED lights are extinguished. This indicates your heater might not have power. Find the breaker box to ensure the heating system fuse is not tripped. Attempt to reset the fuse if it is in the “off” spot. If it rapidly trips after a subsequent reset, don’t try to reset it again and call us at 785-269-0465.
  2. A single light is stable and the other is flashing slowly. This signifies the flame rollout switch is likely not working right. The switch is a critical safety guard that aids in stopping fires and carbon monoxide. You shouldn’t seek to handle this malfunction yourself.
  3. One light is blinking fast and the other is blinking slowly. This typically indicates power polarity has been transposed. Your heating system may have a wiring error that needs specialized support from Scott Temperature.
  4. The pair of lights are flickering slowly. This signifies your heating system’s blower motor probably isn’t running. This part sends heated air from the HVAC system into your house. We can assist in determining what’s wrong with this part.
  5. A single light is blinking slowly and the other is flickering rapidly. This signifies your heater may have insufficient voltage or a short circuit. Get in touch with our specialists at 785-269-0465 for assistance.
  6. One light is flickering on, on, off while the other flashes on, off, on. This means there might be a malfunction with your HVAC system’s control panel or wiring. Scott Temperature can pinpoint the error and repair it.
  7. The pair of lights display alternate slow blinks. This indicates your heater may have a flame error. There might be trouble with its gas supply, gas valve or ignitor control. Call us at 785-269-0465 for help.
  8. A single light flickers slowly while the other remains steady. This typically means your heater’s limit switch is malfunctioning. The switch prevents your heater from becoming too warm. Reach out to the pros at Scott Temperature for support.

Furnace Blower Runs But No Warmth

Here’s what could be at fault when you notice your heater’s blower fan running, but you aren’t gaining any warm air.

  • The duo of lights are giving every other quick blinks. This signifies your furnace ignitor may not be working. This part ignites fuel in your furnace to produce heat and should be serviced by a specialist from Scott Temperature.
