If you’ve been experiencing a burning smell from your air conditioner, and it’s not the popcorn making you nostalgic for those carefree days of summer camp, then there’s a good chance that your AC capacitor is burnt out.
This can be a real pain, especially if it’s the middle of summer and your home is sweltering. You’re not sure what to do, where to turn, or how much this is going to cost you.
In this blog post, we’ll discuss what could be causing your capacitor to burn, and how you can go about fixing it. We’ll also provide some tips on how to prevent this from happening again in the future.
What Causes AC Wires to Burn?
If you’ve ever seen a power line that’s been downed by a storm, you may have noticed that the wires are burned. This is because AC (alternating current) wires conduct electricity by using electromagnetism.
When the current flowing through the wire changes direction, it produces a magnetic field. This magnetic field is what causes the wire to heat up and eventually burn.
How Wires Conduct Electricity
Wires are made of metal because metal is a good conductor of electricity. The electrons in metal atoms are free to move around, which allows them to carry electrical current.
When an electrical current flows through a wire, the electrons bump into each other and push each other along. This movement of electrons creates an electric field.
The strength of this electric field depends on the number of electrons moving through the wire. The more electrons there are, the stronger the electric field will be.
The strength of the electric field also depends on how fast the electrons are moving. The faster they’re moving, the stronger the electric field will be.
How Wires Burn
When an AC current flows through a wire, the direction of the current reverses every half-cycle. This reversal causes the magnetic fields to reverse as well. As a result, the wires heat up from the movement of electrons bumping into each other.
If too much current flows through the wires, they can overheat and catch fire. This is why it’s important to use appropriately sized wires for your electrical needs.
If you need help determining what size wires to use, you can consult an electrician or look up charts online that list common types of electrical loads and their corresponding wire sizes.

What Happens When an AC Capacitor Is Blown?
An air conditioner capacitor is a small, cylindrical device that helps your AC unit start up and run efficiently. The capacitor stores electricity and releases it when the AC unit needs an extra power boost to turn on. A blown capacitor is a common problem with AC units, and it can be dangerous if you don’t know how to handle it.
When an AC capacitor is blown, it means that the device has failed and can no longer store or release electricity. This can happen for a number of reasons, including age, corrosion, or overuse. A blown AC capacitor will prevent your air conditioner from turning on, and if the problem is not fixed quickly, it could lead to more serious issues like compressor failure.
How to Replace a Blown AC Capacitor
If you have a blown AC capacitor, don’t panic! Replacing a blown capacitor is a relatively easy and inexpensive repair that you can do yourself. Just follow these steps:
- Shut off power to the air conditioner at the breaker box.
- Remove the access panel to the air conditioner so you can access the capacitor.
- Disconnect the wires from the old capacitor (be sure to note which wire goes where).
- Remove the old capacitor and take it with you to the hardware store so you can purchase an identical replacement.
- Install the new capacitor in the same position as the old one and reconnect the wires (again, be sure to note which wire goes where).
- Replace the access panel and turn on power to the air conditioner at the breaker box.
- Test your air conditioner to make sure it’s working properly.
- If your air conditioner still isn’t working, call a professional HVAC technician for assistance.
A blown AC capacitor is a common problem that can be easily fixed with a replacement part from your local hardware store.
Just be sure to shut off power to the air conditioner before you begin any repairs, and if you’re unsure of how to proceed, call a professional HVAC technician for help.
How Do I Know If My AC Capacitor Is Blown?
Check the voltage rating
The first thing you’ll want to do is check the voltage rating of your AC capacitor. This is usually printed on the side of the capacitor, and it should match the voltage of your AC unit. If it doesn’t, then it’s likely that your capacitor is blown.
Check for physical damage
Next, you’ll want to check for any physical damage to the capacitor. This can include things like cracks in the housing or loose wires. If you see any damage, then it’s likely that your capacitor is blown.
Check for leaks
Another sign that your AC capacitor is blown is if you see any leaks coming from it. These leaks will usually be either oil or coolant, and they can be a sign that the internal components of the capacitor are damaged.
Check for corrosion
Corrosion on the terminals of your AC capacitor is another sign that it’s blown. This corrosion can prevent electricity from flowing through the capacitor, which will cause it to fail.
Test the capacitor with a multimeter
Finally, you can test the capacitor with a multimeter to see if it’s still working properly. To do this, you’ll need to set the multimeter to the “capacitance” setting and then touch the probes to the terminals of the capacitor. If the reading is “OL” or “infinite,” then this means that your capacitor is most likely blown
Can an AC capacitor be repaired?
Yes, an AC capacitor can be repaired. However, the extent of the repair will depend on the extent of the damage. In some cases, the capacitor may simply need to be cleaned or recharged. In other cases, the capacitor may need to be replaced.
Will the AC fan run if the capacitor is bad?
Yes, the AC fan will run if the capacitor is bad, as the capacitor is used to regulate the flow of electricity to the fan. However, if the capacitor is bad, it may not be able to provide enough power to the fan, which could result in it not running correctly or not at all.
