While your Lennox® heater can’t speak to you, it has a procedure to tell you about a furnace error.

Its motherboard has twin LED lights that can show a fault code. Based on the malfunction, your furnace might show continuous or flashing lights.

Though there are certain elementary HVAC repairs you can complete without an expert, many services are best left to the professionals. When your heater will not kick on or give heated air, reach out to Air Masters Heating & Cooling at 360-205-7115 for skilled furnace repair in Port Orchard.

Our specialists will speedily detect and take care of the breakdown, even if you don’t own a Lennox heating system. We can repair any kinds or makes—and get the comfort returned to your house quickly.

What Does the Flashing Light on My Heater Mean?

Your heating system uses lights to flash code when it is malfunctioning. It also engages these lights to let you know it’s heating properly.

Normal operation consists of:

  • Simultaneous slow flash—furnace running like it should.
  • Simultaneous fast flash—furnace is starting to call for heat.

If you realize that a solitary light blinking slowly and the other flashing fast, your heating system could be having a low flame signal. This can take place even when your furnace is running correctly. It means the flame sensing rod may need to be cleaned or in the incorrect location on the burner. Reach out to us at 360-205-7115 for assistance.

Here are several other of the most routine errors for Lennox heaters.

Heater Won’t Kick On

Here are some of the light patterns you might see when your heating system refuses to or keep heating. Most of these errors need to be handled by an expert, like one from Air Masters Heating & Cooling.

  1. The duo of LED lights are off. This means your HVAC system might not be receiving power. Find the breaker box to make sure the heating system fuse is not tripped. Attempt to reset the fuse if it’s in the “off” area. If it instantly trips after a subsequent reset, don’t touch the breaker and contact us at 360-205-7115.
  2. An individual light is continuous and the other is flashing slowly. This implies the flame rollout switch is possibly malfunctioning. The part is a critical safety mechanism that aids in preventing fires and carbon monoxide. You shouldn’t seek to handle this problem on your own.
  3. An individual light is flashing rapidly and the other is blinking slowly. This typically indicates power polarity has been reversed. Your heating system might have a wiring fault that requires expert assistance from Air Masters Heating & Cooling.
  4. The pair of lights are blinking slowly. This means your heating system’s blower motor probably isn’t working. This component moves warm air from the heating system into your house. We can help in pinpointing what’s causing a problem with this part.
  5. One light is blinking slowly and the other is flickering fast. This indicates your HVAC system might have insufficient voltage or a short circuit. Contact our technicians at 360-205-7115 for support.
  6. One light is flickering on, on, off while the other flickers on, off, on. This signifies there may be a fault with your heating system’s motherboard or wiring. Air Masters Heating & Cooling can find the error and handle it.
  7. The duo of lights are using alternate slow flickers. This signifies your HVAC equipment may have a flame issue. There might be an issue with its gas supply, gas valve or ignitor control. Contact us at 360-205-7115 for help.
  8. An individual light flickers slowly while the other is continuous. This often means your HVAC equipment’s limit switch is malfunctioning. The switch prevents your HVAC equipment from becoming too warm. Get in touch with the professionals at Air Masters Heating & Cooling for assistance.

Heating System Blower Runs But No Heat

Here’s what could be broken when you observe your heating system’s blower fan working, but you aren’t getting any heated air.

  • The pair of lights are showing alternate fast blinks. This means your furnace ignitor may not be working. This piece ignites gas in your heating system to make warm air and should be serviced by an expert from Air Masters Heating & Cooling.
