What Does the Flickering Light on My Furnace Mean?
Your heater uses lights to flash code when it needs to be repaired. It also works this setup to tell you it’s heating like it should.
Normal operation involves:
- Simultaneous slow flash—heating system operating like it should.
- Both lights flash fast—heating system is starting to call for heat.
If you realize that a single light going on and off slowly and the other flashing quickly, your heater might be having a low flame signal. This can happen even when your heating system is running correctly. It means the flame sensing rod might have build-up or in the incorrect location on the burner. Call us at 304-707-0600 for help.
Here are several other of the most typical problems for Lennox heaters.
Furnace Won’t Turn On
Here are a few of the light arrangements you may notice when your heater won’t turn on or keep operating. The majority of these errors have to be taken care of by a technician, for instance from Appalachian Heating.
- Both LED lights aren’t lit. This means your HVAC system might not have electricity. Look at the breaker box to ensure the heater fuse is not triggered. Try resetting the fuse if it is in the “off” spot. If it immediately flips after a subsequent reset, don’t touch the breaker and call us at 304-707-0600.
- An individual light is continuous and the other is blinking slowly. This implies the flame rollout switch is possibly malfunctioning. The part is an important safety guard that aids in stopping fires and carbon monoxide. You shouldn’t attempt to fix this malfunction yourself.
- A single light is flashing fast and the other is blinking slowly. This likely signifies power polarity has been inverted. Your furnace could have a wiring fault that calls for professional aid from Appalachian Heating.
