What Does the Flickering Light on My Heating System Mean?

Your heater uses lights to flash code when it is malfunctioning. It also uses these lights to relay it’s working correctly.

Regular operation consists of:

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

If you realize that a solitary light going on and off slowly and the other flashing fast, your furnace could be having a low flame signal. This can take place even when your heating system is running like it should. It indicates the flame sensing rod could have buildup or in the wrong spot on the burner. Call us at 201-426-0650 for assistance.

Here are a few other of the most typical errors for Lennox heating systems.

Heater Refuses to Start

Here are some of the light sequences you might notice when your heating system will not or keep heating. The majority of these problems have to be fixed by a technician, such as one from ACE Solutions.

  1. All LED lights aren’t lit. This indicates your heating system might not have power. Examine the breaker box to confirm the heating system fuse hasn’t tripped. You should reset the fuse if it’s in the “off” position. If it instantly flips after you reset it, don’t try to reset it again and contact us at 201-426-0650.
  2. An individual light is continuous and the other is flickering slowly. This implies the flame rollout switch is possibly open. The part is a critical safety guard that assists in preventing fires and carbon monoxide. You shouldn’t seek to take care of this malfunction yourself.
  3. One light is blinking quickly and the other is flashing slowly. This often indicates power polarity has been reversed. Your furnace may have a wiring issue that calls for professional help from ACE Solutions.
  4. The pair of lights are flashing slowly. This means your heater’s blower motor possibly isn’t working. This piece sends warm air from the heating system into your space. We can aid in determining what’s wrong with this component.
