The orange light on a furnace typically indicates that the pilot light is lit.

What Does Orange Light On Furnace Mean

When the orange light on your furnace is lit, it usually signifies one of two things. Firstly, it could mean that there is an issue with the furnace, such as a blown fuse or a problem with the gas line. Secondly, it could indicate that the furnace is not getting enough power to start up properly. In either case, you should consult a professional to determine the exact cause and then take appropriate action. If you do choose to work on your furnace yourself, be sure to shut off all power sources, including the fuse box and main switch before beginning any repairs. By checking and understanding the orange light on your furnace, you can identify potential issues quickly and efficiently.

No Heat

When the orange light on your furnace is lit, it typically indicates that the furnace is not producing heat. In most cases, this means that there is an issue with the furnace itself, or with one of the components in its system. To determine the cause of this issue, it’s important to inspect the furnace and look for any visible signs of damage. Additionally, you should check for any blockages in the air ducts or vents that could be preventing air from circulating properly throughout the home.

Flame Sensor

The orange light may also indicate an issue with your furnace’s flame sensor. The flame sensor is a device located inside the furnace that monitors whether or not there is a flame present when the unit is operating. If it detects no flame, it will shut down the system in order to prevent further damage from occurring. To resolve this issue, you’ll need to replace the flame sensor and ensure that all related wiring connections are secure and intact.

Air Filter

If your furnace’s orange light is lit up but you’re still getting some heat, then it could be due to a clogged air filter. Over time, air filters can become clogged with dirt and debris which can reduce airflow and cause your system to work harder than necessary in order to produce adequate heat. To check if this is causing your issue, remove your air filter and inspect it for any dirt or debris buildup. If necessary, replace it with a new one and see if that resolves the problem.

Ignition System

The orange light on your furnace may also indicate an issue with its ignition system. The ignition system includes several components such as spark plugs, electrodes and igniters that work together to create a spark which lights up the burner when your unit needs to produce heat. If these components are worn out or damaged in any way, they may not be able generate enough spark power which can cause your unit to shut down automatically until they are replaced or repaired by a trained technician.
