How Do I Know if My Furnace Flame Sensor is Bad?

There are many individual components within your gas furnace that have to be working properly in order for the whole unit to function as it should. One of the key components is called a flame sensor, and you will quickly find yourself left in the cold if it stops working. This article will explain what this part does and how you can determine if it might be causing problems with your furnace.

 

Managing the heating and air system in your home doesn’t have to be complicated – or unnecessarily expensive. By turning to Berico for HVAC service in Greensboro, you can be sure that you’ll be in good hands from start to finish on any upcoming project. Reach out today to get started.

 

What is a Flame Sensor?

Your Furnace would not be able to operate properly – and safely – without the inclusion of a flame sensor. This device is designed to detect a flame when the gas valve is open and gas is being allowed to flow into the furnace. If this sensor doesn’t detect an active flame, the gas supply will be shut off as a safety feature.

 

This is a creative way for furnace manufacturers to avoid creating a dangerous situation in which the gas flows into a furnace that doesn’t have the flame needed to combust the gas. The only problem is that over time, the flame sensor can get dirty or develop other problems, and it might stop working correctly. In other words, it may not detect a flame when one actually is present, and the furnace will struggle to work properly as a result.

 

Some Signs of Trouble

You don’t need to be a furnace repair professional to notice some issues that could point to a bad flame sensor. For example, if the furnace is cycling on and off way more often than it should, that could be the fault of this sensor. As the sensor thinks that the flame is out, it will shut off the furnace until the thermostat tries to kick it on again. A properly functioning furnace will run for a while before it shuts back off – if that isn’t happening, you should at least consider the possibility of the sensor being at fault.

 

Also, if your furnace isn’t creating heat as it should, you may again have a flame sensor problem. In this case, the sensor isn’t doing its job of detecting that the flame has gone out, and it’s allowing the furnace to run without any flame burning. That’s not only a problem in terms of not getting any hot air, but it can also be dangerous because gas will be flowing and not getting combusted.

Why is My Furnace Blowing Cold Air?

When you hear your furnace kick on in the background while going about your normal life, you naturally expect to feel warm air blowing through the house a few moments later. If that doesn’t happen – and cold air comes out of the vents instead – you’ll immediately know that something is wrong. This article will take a look at some possible causes of your furnace failing to produce the warm air you need to stay comfortable all winter long.

Faulty Ignition Leading to No Fire

There needs to be a flame within your furnace to heat the air that is being run through the system. If you don’t have a flame due to an ignition problem, you won’t have the warm air you expect while the furnace is on. Fortunately, this is a problem that is a pretty easy issue to fix for a professional technician, so if this is the only issue with the furnace, it could be back up and running rather quickly.

 

Problems with the Control Board

It is the job of the control board to act as the brain for the furnace and send out the right signals to trigger proper operation. That usually goes fine, but if something goes wrong with the control board, it could send out signals that aren’t in line with what the system should be doing. If a faulty control board is diagnosed by your technician, having it replaced is another pretty simple fix.

 

A Clogged Air Filter

One of your most important jobs as a homeowner is to make sure the air filter that serves your heating and cooling system is replaced regularly. Through ongoing use, the air filter is going to gradually clog up, and less and less air will be able to make it through the filter. That restricted airflow will make it harder to efficiently distribute heat around the home, and the furnace will struggle to keep up with what the thermostat is demanding. Swap out your air filter frequently to avoid running into this problem.

 

The Vents Are Closed

This isn’t an instance of a furnace blowing cold air, but it happens enough to warrant mentioning: Did you or someone else in the home close some or all of the vents recently? This is an easy mistake to make, and if you forget that the vents are closed, you won’t be getting the airflow or the warming that you expect. Of course, you won’t need a technician to come in to solve this problem – just get all of the vents opened back up and you should be all set.
