What Does A Flashing Green Light On Furnace Mean?

The role of the pilot light in the furnace is to help provide a constant source of flame. It is used to light burners in furnaces.

The pilot light usually uses a small amount of gas to create a flame, which is then used to ignite the larger gas source needed to power the furnace. If the indicator light goes out, the oven cannot generate heat.

However, if the indicator light is on but the oven is not, some underlying problems may endanger the oven system.

The most common cause of a faulty igniter is that it is rusted or damaged. If your igniter isn’t sparking, it’s because it’s not getting enough power.

Dead or faulty batteries are one of the most common problems with a faulty igniter. The batteries in your lighter will start to lose their charge over time and will not be able to provide enough power to spark.

Another possibility is that the cable connecting the igniter to the battery is damaged. This wire can wear out over time and, if not replaced, can eventually cause the igniter to fail.

Why Won’t My Furnace Turn On?

If your igniter is not producing any sparks, it probably needs to be replaced.

Your oven may not light up due to a clogged oven burner. This is usually caused by a build-up of dirt and dust on the burner and can be easily removed with a good cleaning.

Most ovens have an access panel that will allow you to reach the burner for cleaning. If you do not clean the burner regularly, it will become clogged with soot and eventually stop working.

Why Does My Furnace Make A “boom” Sound When It Starts Up?

If your oven has an access panel, open it and look at the burner. If you see a build-up of soot or dirt, this may be why the oven is not lit.

A dirty or faulty flame sensor is one of the most common causes of a furnace going out. This sensor is a safety device that informs the oven if there is a flame.

If the sensor is dirty and cannot detect the flame, it will disable the oven. A faulty flame sensor will also prevent the furnace from burning, even if the pilot light is on.

Things To Check When Your Furnace Won’t Turn On

What To Do If Your Furnace Is Leaking Water

If the burner line is too short, the oven will not be able to operate at its full potential. On the other hand, a very small jet will limit the heating capacity of your oven.

The jet in a furnace is responsible for igniting the fuel. The size of the spray is also an important factor because it must be large enough to provide a good, strong flame.

When it comes to more complex gas related problems, we strongly recommend that you do not handle any of them yourself.
