While your Lennox® heating system can’t talk to you, it does have a process to get your attention when there’s a furnace error.

Its control panel has two LED lights that can share a fault code. Depending on the failure, your heater could use continuous or flashing lights.

Though there are a few simple heating adjustments you can complete on your own, most repairs are best taken care of by the professionals. When your heating system will not start or provide heat, contact Point Heating & Cooling at 715-504-0533 for experienced furnace repair in Plover.

Our technicians will quickly discover and handle the malfunction, even if you don’t use a Lennox heating system. We can repair any types or models—and get the warmth returned to your home without delay.

What Does the Blinking Light on My Heater Mean?

Your heating system depends on lights to flash code when it is malfunctioning. It also engages these lights to tell you it’s heating properly.

Correct heating consists of:

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

If you notice a solitary light flashing slowly and the other going on and off fast, your heating system might have a low flame signal. This can happen even when your heater is heating properly. It signifies the flame sensing rod could have buildup or in the wrong location on the burner. Contact us at 715-504-0533 for support.

Here are a few other of the most common problems for Lennox furnaces.

Heating System Will Not Start

Here are a few of the light patterns you may observe when your heater won’t turn on or keep heating. The bulk of these issues have to be handled by an expert, for instance from Point Heating & Cooling.

  1. The duo of LED lights are extinguished. This signifies your heating system might not have power. Look at the breaker box to confirm the heater fuse isn’t triggered. Try resetting the fuse if it’s in the “off” spot. If it instantly flips after a subsequent reset, don’t touch the breaker and get in touch with us us at 715-504-0533.
  2. An individual light is continuous and the other is flashing slowly. This implies the flame rollout switch is likely open. The part is a critical safety mechanism that helps in preventing fires and carbon monoxide. You shouldn’t attempt to take care of this fault yourself.
  3. An individual light is flickering rapidly and the other is blinking slowly. This likely means power polarity has been transposed. Your heating system may have a wiring issue that needs specialized support from Point Heating & Cooling.
  4. Both lights are blinking slowly. This signifies your heating system’s blower motor likely isn’t running. This part distributes warm air from the HVAC system into your rooms. We can help in figuring out what’s wrong with this component.
  5. A single light is blinking slowly and the other is flashing rapidly. This indicates your heater could have insufficient voltage or a short circuit. Get in touch with our experts at 715-504-0533 for help.
  6. One light is flashing on, on, off while the other blinks on, off, on. This indicates there might be a fault with your heater’s control board or wiring. Point Heating & Cooling can find the fault and handle it.
  7. The pair of lights display alternating slow flickers. This signifies your heating system possibly has a flame issue. There could be a problem with its gas supply, gas valve or ignitor control. Get in touch with us at 715-504-0533 for help.
  8. A single light flashes slowly while the other remains continuous. This usually means your heater’s limit switch is experiencing an error. The switch prevents your HVAC system from becoming too warm. Get in touch with the professionals at Point Heating & Cooling for assistance.

Furnace Blower Works But No Warmth

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

  • The duo of lights are showing alternate rapid flickers. This signifies your furnace ignitor may be broken. This part ignites fuel in your HVAC equipment to make warm air and should be fixed by an expert from Point Heating & Cooling.
