What Does the Flashing Light on My Heating System Mean?

Your heating system relies 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.

Normal heating consists of:

  • Concurrent slow flash—heating system working like it should.
  • Both lights flash fast—heater is beginning to call for heat.

If you see a lone light flashing slowly and the other flashing rapidly, your heater might have a low flame signal. This can occur even when your heater is heating like it should. It indicates the flame sensing rod might need to be cleaned or in the incorrect area on the burner. Contact us at 276-302-0076 for help.

Here are some of the most common issues for Lennox HVAC systems.

Furnace Won’t Kick On

Here are some of the light patterns you might observe when your furnace will not or keep running. The majority of these issues need to be handled by a professional, for instance from HCE Systems.

  1. All LED lights are off. This signifies your heating system might not be receiving power. Look at the breaker box to confirm the heater fuse hasn’t flipped. Try resetting the fuse if it’s in the “off” position. If it immediately flips following a reset, don’t try to reset it again and contact us at 276-302-0076.
  2. One light is continuous and the other is flashing slowly. This shows the flame rollout switch is may be malfunctioning. The switch is an essential safety guard that aids in stopping fires and carbon monoxide. You shouldn’t attempt to fix this problem without professional help.
  3. A single light is blinking fast and the other is flashing slowly. This typically indicates power polarity has been reversed. Your heater could have a wiring problem that calls for professional support from HCE Systems.
  4. All lights are flickering slowly. This indicates your furnace’s blower motor possibly isn’t working. This component circulates heated air from the HVAC system into your residence. We can help in pinpointing what’s causing a problem with this part.
