Blown capacitors are not good for your air conditioning system. While AC’s do run on your electricity, you have capacitors located throughout your AC which provide your system with the power boost it needs to run your cooling cycle. Therefore, if your capacitor burns out, just simply having your AC hooked up won’t mean a thing since your capacitor is responsible for the operations of your system. We’re going to talk all about blown out capacitors and how you should identify them and ultimately bring them back to working condition.
What is a capacitor?
The capacitor is a core element of your AC that stores energy and disperses it through your AC system during its cooling cycle. Location-wise, you can usually find them by the motors for your compressor, air handler, and outdoor fan.
Your start capacitors are responsible for giving all your AC motors a jump start to get them running effectively. After everything is up to speed, the run capacitors keep everything going with continuous energy if the motors need an extra boost. All in all, this effective system releases a burden on your AC’s motors and keeps everything running smoothly.
What causes blown capacitors?
Some problems that can cause your capacitor to blow out include:
- A power surge due to weather – Like any other electronics in your home, weather can have a destructive effect on your capacitor due to power surgesShort-circuiting
- Short-circuiting – Short circuits can be present in your AC electrical components which can directly affect your capacitor. This is why it’s key to keep your AC maintained through yearly maintenance.
- Overheating – Especially in San Antonio, the hot weather can be a bit extreme and therefore overheat your AC unit when your capacitor is trying to work overtime.
- Age of the capacitor – like most expensive things in our life, your capacitor may be dead from just being too old.
What are the signs of blown capacitors?
- Something smells burnt – When your electrical components overheat, you’ll be able to literally smell the burning of your capacitor being cooked.
- Hard Starts – If your AC stutters when you’re trying to turn it on, or doesn’t want to start a cooling cycle, you can almost bet that your capacitor has gone out.
- Humming and clicking – Clicking noises may be present when your capacitor starts to burn out. Once it’s completely burnt out, your unit may start humming loud.
How can blown capacitors be fixed?
Most of the time, you’ll most likely need a brand new capacitor to swap out for the old one. This kind of work should only be done by a licensed technician who knows the ins and outs of your unit and who have received training for the replacement.
