Do you smell a strong burning smell whenever you turn on your furnace? In that case, you must identify what’s causing this persistent smell immediately. If left untreated, this could lead to potentially fatal system damage.
With that, here are the five most common reasons why your furnace smell like it’s burning and what you can do about it.
Although it’s normal for furnaces to have a burning smell for its first time of operation, this should not stay long. There are several possible reasons why your furnace may smell like it’s burning plastic every time you turn it on.
Below are the following possible reasons.
Dust Burn Out
After a long time of being idle, your furnace will accumulate dust. This dust may settle on different internal components of your furnace, such as the heat exchanger and burners. And when you turn it on for the first time again, it will give off a burning-like smell.
In most cases, the smell should come from your home’s vents. Most of the time, the burning smell will dissipate in time. However, if it doesn’t, you should reach our heating professionals to help you identify the problem.
Clogged Air Filter
One other simple reason why your furnace smells like burning is when you have a clogged air filter. If this is the case, your blower motor will suffer from unnecessary stress, which may cause overheating, hence the burning smell.
Be sure to regularly replace your furnace’s air filters at least once a month to ensure that your heating system is in its tip-top shape.
Smoke or Oil Smell
If you have an oil furnace that smells like burning oil, be sure to replace the oil filter to avoid overheating. If the smell persists, contact our pros to diagnose and repair the problem.
We also advise you to turn your heating unit off until certain repairs have been made, as your unit could catch on fire if it continues to operate.
If your circuit board or fan motor overheats, this will give off a stench that’s something comparable to the smell of gunpowder. In this case, immediately turn off your unit and have a heating specialist make the necessary repairs.
In most cases, your furnace will automatically lower its heating power whenever it’s starting to overheat. However, if it doesn’t, this could indicate that your heating system’s safety feature is broken and may need an immediate fix.
Without a functionally working safety feature, there’s a great chance of electrical malfunction and can present as a major safety hazard for you, your family, and your property. Let our team inspect the electrical components of your heating system to keep you safe from any harm.
