What Does the Flickering Light on My Heater Mean?

Your heater relies on lights to flash code when it requires repairs. It also uses this system to let you know it’s operating correctly.

Regular heating involves:

  • Concurrent slow flash—furnace working correctly.
  • Concurrent fast flash—furnace is initiating the call for heat.

If you see a solitary light flashing slowly and the other flashing quickly, your heater might have a low flame signal. This can take place even when your heating system is operating correctly. It signifies the flame sensing rod may need to be cleaned or in the wrong spot on the burner. Contact us at 224-412-8308 for support.

Here are several other of the most routine problems for Lennox HVAC systems.

Furnace Will Not Turn On

Here are many of the light arrangements you could notice when your heater will not or keep heating. The bulk of these problems have to be handled by an expert, such as one from Controlled Comfort HVAC.

  1. The pair of LED lights aren’t lit. This means your HVAC system might not be receiving power. Examine the breaker box to make sure the heating system fuse is not triggered.

The component is an essential safety mechanism that assists in preventing fires and carbon monoxide. You shouldn’t seek to repair this issue without professional help.
