While your Lennox® furnace isn’t able to chat with you, it possesses a way to get your attention when there’s a furnace error.

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

Although there are a few simple furnace fixes you can finish on your own, most services are best handled by experts. When your furnace won’t kick on or deliver heat, get in touch with JW Brager Heating and Cooling at 608-447-0555 for professional furnace repair in Mount Horeb.

Our technicians will quickly determine and repair the issue, even if you don’t have a Lennox heating system. We can repair any kinds or makes—and get the heat returned to your residence without delay.

What Does the Flickering Light on My Heating System Mean?

Your heater relies on lights to flash code when it requires repairs. It also works this system to relay it’s working properly.

Regular operation includes:

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

If you notice a single light going on and off slowly and the other flashing quickly, your heating system might be having a low flame signal. This can take place even when your heating system is operating like it should. It means the flame sensing rod could need to be cleaned or in the incorrect location on the burner. Contact us at 608-447-0555 for assistance.

Here are a few other of the most routine faults for Lennox heating systems.

Furnace Will Not Turn On

Here are a few of the light sequences you might see when your furnace refuses to or keep heating. The majority of these problems must be taken care of by a professional, such as one from JW Brager Heating and Cooling.

  1. The duo of LED lights aren’t lit. This means your HVAC system might not be receiving power. Look at the breaker box to confirm the heater fuse is not triggered. Try resetting the fuse if it is in the “off” spot. If it instantly trips after a subsequent reset, don’t touch the breaker and call us at 608-447-0555.
  2. An individual light is unchanging and the other is flashing slowly. This shows the flame rollout switch is likely not working right. The switch is a critical safety tool that aids in avoiding fires and carbon monoxide. You shouldn’t try to take care of this fault yourself.
  3. One light is blinking quickly and the other is flashing slowly. This often means power polarity has been reversed. Your furnace could have a wiring issue that requires professional help from JW Brager Heating and Cooling.
  4. Both lights are blinking slowly. This signifies your heating system’s blower motor likely isn’t running. This piece circulates warm air from the heating system into your rooms. We can assist in pinpointing what’s wrong with this component.
  5. One light is flickering slowly and the other is flickering rapidly. This indicates your heater might have not enough voltage or a short circuit. Contact our experts at 608-447-0555 for assistance.
  6. One light is blinking on, on, off while the other blinks on, off, on. This indicates there might be trouble with your HVAC system’s control panel or wiring. JW Brager Heating and Cooling can locate the problem and take care of it.
  7. The pair of lights display alternating slow flickers. This means your heater possibly has a flame issue. There might be a problem with its gas supply, gas valve or ignitor control. Call us at 608-447-0555 for assistance.
  8. A single light blinks slowly while the other is steady. This usually signifies your heater’s limit switch is experiencing an error. The switch keeps your heater from becoming too warm. Get in touch with the pros at JW Brager Heating and Cooling for assistance.

Furnace Blower Runs But No Warm Air

Here’s what might be broken when you hear your heating equipment’s blower fan running, but you aren’t receiving any warm air.

  • The duo of lights are showing alternate fast blinks. This indicates your furnace ignitor may not be in working order. This piece ignites gas in your heating system to produce warm air and should be serviced by a technician from JW Brager Heating and Cooling.
