While your Lennox® heating system cannot speak to you, it does have a method to communicate a furnace error.

Its motherboard has double LED lights that can share a fault code. Depending on the issue, your heating system might show continuous or flashing lights.

While there are various elementary HVAC adjustments you can finish yourself, many repairs are best handled by experts. When your heating system refuses to start or put out heat, get in touch with Just Right Heating and Cooling at 513-392-4969 for experienced furnace repair in Goshen.

Our experts will swiftly identify and repair the problem, even if you don’t have a Lennox heater. We can fix whichever brands or models—and get the comfort returned to your house without delay.

What Does the Flashing Light on My Heater Mean?

Your furnace relies on lights to flash code when it is malfunctioning. It also works this system to tell you it’s working like it should.

Regular operation includes:

  • Concurrent slow flash—heater operating correctly.
  • Simultaneous fast flash—heater is starting to call for heat.

If you notice a solitary light blinking slowly and the other going on and off rapidly, your heating system may have a low flame signal. This can take place even when your heating system is operating like it should. It signifies the flame sensing rod could need to be cleaned or in the bad location on the burner. Call us at 513-392-4969 for assistance.

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

Furnace Will Not Start

Here are a few of the light sequences you could notice when your heater will not or keep heating. The bulk of these problems have to be repaired by a specialist, like one from Just Right Heating and Cooling.

  1. All LED lights are off. This signifies your heater might not be receiving power. Look at the breaker box to make sure the heating system fuse is not tripped. Attempt to reset the fuse if it’s in the “off” spot. If it immediately trips following a reset, don’t touch the breaker and get in touch with us us at 513-392-4969.
  2. A single light is unchanging and the other is flickering slowly. This implies the flame rollout switch is likely not working right. The part is an essential safety guard that helps in stopping fires and carbon monoxide. You shouldn’t seek to take care of this fault yourself.
  3. One light is blinking fast and the other is flickering slowly. This likely means power polarity has been inverted. Your heating system may have a wiring error that needs expert support from Just Right Heating and Cooling.
  4. The duo of lights are flickering slowly. This means your heater’s blower motor likely isn’t running. This piece distributes hot air from the HVAC system into your space. We can help in figuring out what’s causing an issue with this piece.
  5. One light is blinking slowly and the other is flashing quickly. This signifies your HVAC system may have insufficient voltage or a short circuit. Call our experts at 513-392-4969 for assistance.
  6. One light is flashing on, on, off while the other blinks on, off, on. This indicates there could be a malfunction with your heater’s control panel or wiring. Just Right Heating and Cooling can find the fault and handle it.
  7. Both lights display alternate slow flickers. This indicates your heater may have a flame issue. There could be a problem with its gas supply, gas valve or ignitor control. Reach out to us at 513-392-4969 for help.
  8. An individual light flashes slowly while the other is continuous. This often indicates your HVAC equipment’s limit switch is experiencing an error. The switch keeps your HVAC system from getting too hot. Get in touch with the specialists at Just Right Heating and Cooling for help.
