Have you ever heard loud bangs from the basement or smelled an unpleasant odour coming from your vents? Strange signs like these often point to furnace malfunction, and different reasons could cause it. What’s important here is to find out the root cause and remedy any issues before they require costly repairs. If you are worried about your heating system overheating, then you need to know how to recognize the signs. 

Signs Your Furnace Is Overheating

The first apparent sign is when you smell a burning odour of hot metal or components from the vents. Next, you will hear bangs or clunks that are unusually loud. The bangs and other loud sounds often indicate a component that is malfunctioning or other device failures. 

Another sign is when your furnace keeps turning on and off by itself. There are situations when the furnace will attempt to reheat and be cut off by a safety device. 

What To Do With An Overheating Furnace

Most of the time, an overheating furnace is caused by the lack of airflow or a component failure. When the problem has to do with the airflow, it will be restricted due to various reasons, such as blocked vents. For this reason, you might want to inspect your vents because furniture or other objects could be restricting the airflow as well.

Your vents can also be clogged or just plain dirty, which then leads to a restricted airflow in the system. Keep in mind to change your filters quarterly. The duct and cover must be inspected as well because they can be sources of restricted airflow. 

When it comes to faulty components, you need to inspect the coil and toil. If these are damaged, they can lead to short-cycling and overheating. 

Likewise, the low blow must be checked because if the blower fan is inhibited with dust and dirt, it can lead to overheating. For homeowners who have electric heating systems, be sure to check the sequencer. If there’s something wrong with the device, it can affect the fan timing and lead to an erratic and overactive limit switch. Also, check the limit switch and wire connections to ensure that they are functioning optimally.

In the case that the reason behind the overheating is due to old age, the most logical step here is to opt for a replacement. There’s no point in having it repaired because eventually, it will give out again, and you will pay for a repair again. Avoid the costly repairs and get yourself a new furnace instead because they can last you another 15-20 years!

Conclusion

If you suspect your furnace is overheating, the best thing to do is call a professional to identify the root cause of the problem. Make sure not to put off maintaining this fixture, especially since the cold season is fast approaching. You don’t want your heating system to break down in the middle of a cold winter day, right? Because of this, make sure you find a furnace repair company that can deliver quality services. 

As much as possible, don’t try to solve it on your own if you don’t have any experience with furnace repairs. You could do more harm than good to it, leading to bigger problems down the line and costly repairs!
