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

Its control panel has double LED lights that can display a fault code. Depending on the malfunction, your heater might use steady or flashing lights.

While there are a few elementary HVAC fixes you can complete on your own, many fixes are best left to the professionals. When your heating system will not turn on or deliver warm air, call Point Heating & Cooling at 715-504-0533 for professional furnace repair in Plover.

Our specialists will swiftly determine and repair the issue, even if you don’t have a Lennox heater. We can service all brands or makes—and get the heat reintroduced to your residence quickly.

What Does the Blinking Light on My Heater Mean?

Your heating system depends on lights to flash code when it isn’t working right. It also engages this system to tell you it’s working like it should.

Correct operation includes:

  • Concurrent slow flash—heating system working correctly.
  • Both lights flash fast—heater is initiating the call for heat.

If you realize that a single light flashing slowly and the other flashing rapidly, your heating system may be experiencing a low flame signal. This can occur even when your heating system is heating correctly. It signifies the flame sensing rod could have buildup or in the wrong spot on the burner. Reach out to us at 715-504-0533 for assistance.

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

Heating System Refuses to Start

Here are some of the light sequences you might notice when your heating system refuses to or keep operating. The bulk of these issues have to be taken care of by an expert, like one from Point Heating & Cooling.

  1. The duo of LED lights aren’t lit. This means your heating system might not have electricity. Find the breaker box to confirm the heater fuse has not flipped. Try resetting the fuse if it’s in the “off” spot. If it instantly trips following a reset, don’t touch the breaker and call us at 715-504-0533.
  2. A single light is unchanging and the other is flashing slowly. This shows the flame rollout switch is likely open. The component is an essential safety mechanism that aids in stopping fires and carbon monoxide. You shouldn’t attempt to handle this problem without professional help.
  3. A single light is flashing quickly and the other is blinking slowly. This likely indicates power polarity has been transposed. Your furnace may have a wiring problem that needs specialized assistance from Point Heating & Cooling.
  4. The duo of lights are flickering slowly. This indicates your heater’s blower motor possibly isn’t working. This piece distributes warm air from the furnace into your space. We can aid in figuring out what’s wrong with this piece.
  5. An individual light is blinking slowly and the other is blinking rapidly. This means your heater might have not enough voltage or a short circuit. Call our technicians at 715-504-0533 for support.
  6. One light is flickering on, on, off while the other flashes on, off, on. This indicates there may be a malfunction with your HVAC system’s control panel or wiring. Point Heating & Cooling can locate the problem and fix it.
  7. Both lights show alternate slow flashes. This means your heating system possibly has a flame error. There might be trouble with its gas supply, gas valve or ignitor control. Call us at 715-504-0533 for assistance.
  8. An individual light flickers slowly while the other remains steady. This usually means your heater’s limit switch is malfunctioning. The switch prevents your heater from becoming too warm. Call the professionals at Point Heating & Cooling for support.

Heating System Blower Runs But No Heat

Here’s what might be at fault when you observe your heating equipment’s blower fan working, but you aren’t getting any warmth.

  • The pair of lights are showing alternate rapid flashes. This indicates your furnace ignitor may not be in working order. This piece ignites energy in your furnace to make warm air and should be fixed by an expert from Point Heating & Cooling.
