Its control board has twin LED lights that can display a fault code. Subject to the malfunction, your heating system could show solid or flashing lights.

What Does the Flickering Light on My Heater Mean?

Your furnace depends on lights to flash code when it isn’t working right. It also works these lights to tell you it’s heating like it should.

Normal operation consists of:

  • Concurrent slow flash—heating system running correctly.
  • Simultaneous fast flash—furnace is beginning to call for heat.

If you see a solitary light blinking slowly and the other blinking fast, your heating system might be experiencing a low flame signal. This can take place even when your heater is heating correctly. It signifies the flame sensing rod could need to be cleaned or in the incorrect spot on the burner. Call us at 734-284-1224 for assistance.

Here are some of the most routine problems for Lennox heating systems.

Heater Will Not Turn On

Here are a few of the light patterns you might see when your heater will not or keep heating. The bulk of these problems need to be handled by an expert, such as one from Gee & Missler Heating & Air Conditioning.

  1. Both LED lights are off. This means your heating system might not have electricity. Go to the breaker box to make sure the heater fuse hasn’t flipped. Try resetting the fuse if it is in the “off” spot. If it immediately turns off after you reset it, don’t touch the breaker and contact us at 734-284-1224.
  2. An individual light is stable and the other is flickering slowly. This implies the flame rollout switch is likely open. The switch is an essential safety mechanism that assists in stopping fires and carbon monoxide. You shouldn’t seek to fix this fault without professional help.
  3. One light is flashing quickly and the other is flashing slowly. This often means power polarity has been inverted. Your heating system might have a wiring fault that calls for specialized aid from Gee & Missler Heating & Air Conditioning.
  4. The pair of lights are blinking slowly. This indicates your heating system’s blower motor likely isn’t running. This component distributes hot air from the heater into your residence. We can help in pinpointing what’s wrong with this piece.
  5. An individual light is blinking slowly and the other is flashing fast. This indicates your heating system might have insufficient voltage or a short circuit. Reach out to our technicians at 734-284-1224 for help.
  6. One light is blinking on, on, off while the other flashes on, off, on. This signifies there might be a malfunction with your heating system’s motherboard or wiring. Gee & Missler Heating & Air Conditioning can locate the fault and fix it.
  7. The duo of lights are using alternating slow flashes. This signifies your heating system likely has a flame issue. There could be a problem with its gas supply, gas valve or ignitor control. Get in touch with us at 734-284-1224 for help.
  8. A single light flashes slowly while the other stays solid. This typically indicates your heating system’s limit switch is not working. The switch keeps your HVAC system from getting too hot. Call the experts at Gee & Missler Heating & Air Conditioning for help.

Heater Blower Works But No Warm Air

Here’s what might be broken when you hear your heating system’s blower fan working, but you aren’t receiving any heated air.
