What Does the Blinking Light on My Heater Mean?

Your heating system relies on lights to flash code when it isn’t working right. It also uses these lights to let you know it’s working correctly.

Regular heating consists of:

  • Concurrent slow flash—furnace operating like it should.
  • Simultaneous fast flash—furnace is initiating the call for heat.

If you realize that a single light blinking slowly and the other flashing quickly, your furnace might be having a low flame signal. This can happen even when your furnace is heating correctly. It means the flame sensing rod could be dirty or in the wrong area on the burner. Call us at 623-208-6444 for assistance.

Here are several other of the most typical errors for Lennox HVAC systems.

Furnace Will Not Turn On

Here are some of the light sequences you may notice when your furnace refuses to or keep heating. Most of these errors have to be handled by a professional, such as one from Cooler Tymes LLC.

  1. All LED lights are extinguished. This signifies your HVAC system might not be receiving power. Examine the breaker box to confirm the heating system fuse is not flipped. Try resetting the fuse if it is in the “off” area. If it immediately trips after a subsequent reset, don’t touch the breaker and call us at 623-208-6444.
  2. A single light is continuous and the other is blinking slowly. This implies the flame rollout switch is possibly open. The switch is an essential safety guard that aids in avoiding fires and carbon monoxide. You shouldn’t attempt to repair this issue on your own.
  3. An individual light is blinking quickly and the other is blinking slowly. This typically indicates power polarity has been inverted. Your heater could have a wiring issue that requires expert support from Cooler Tymes LLC.
  4. The duo of lights are blinking slowly. This signifies your furnace’s blower motor possibly isn’t working. This part distributes heated air from the HVAC system into your residence. We can assist in determining what’s causing a problem with this component.
  5. A single light is blinking slowly and the other is flickering quickly. This signifies your heating system might have not enough voltage or a short circuit. Contact our technicians at 623-208-6444 for help.
  6. One light is blinking on, on, off while the other blinks on, off, on. This signifies there may be an issue with your heater’s control board or wiring. Cooler Tymes LLC can pinpoint the fault and handle it.
  7. The pair of lights are using alternating slow flickers. This signifies your heater likely has a flame problem. There may be an issue with its gas supply, gas valve or ignitor control. Get in touch with us at 623-208-6444 for support.
  8. A single light blinks slowly while the other stays continuous. This usually means your HVAC equipment’s limit switch is malfunctioning. The switch stops your heating system from becoming too warm. Reach out to the specialists at Cooler Tymes LLC for help.
