How do I Know if my AC Wiring is Faulty?
TechXpert verified by Ron Tolbert
The most visible sign of faulty AC wiring is exposed, frayed, or otherwise damaged AC wires. If your AC system is operating irregularly, there could be an issue with your system’s wiring and electricity flow. Faulty wires can also affect other parts of your system, like the circuit breakers or thermostat.
Why Your Wires Wig Out
Over time, overusing anything will wear it out. This goes for your AC wires as well as the other electrical parts of your system. Your AC system consumes a lot of electricity, and if your wires become overwhelmed, they can short out and damage other parts of your system. In turn, it’s important to check for issues that could be related to faulty wiring.
Exposed or Frayed Wires
A wire-related fire may not be the best occasion for roasting marshmallows this summer. Exposed or frayed wires connected to your AC system should be fixed immediately to avoid spontaneous, damaging flames.
Most homes have a split AC system where there’s one unit indoors and one outdoors. This pair is connected by a series of electrical wires in order for them to work together. If any of these wires lose their protective covering or become frayed, they can produce sparks that will ignite and feed dangerous fires. It’s vital to check your cooling system so your house doesn’t (literally) burn up.
Wires Aren’t Tightened
You need to run a tight ship to keep your wires from arcing. If your wires aren’t tightened properly, electricity can take a wrong turn and jump to a nearby grounded object. Time to call a licensed electrician. A small fire can be triggered by a lightning strike or power surge.
If you notice your AC system’s power cutting out intermittently during operation, there could be an issue with the wiring. Once electrical currents rise too high and your system overheats, your AC may shut itself off from the electrical panel and stop working. For example, if you see your outdoor fan stopping at high speed, faulty wiring may be the culprit and the case won’t be closed until the wires are fixed.
There are multiple electrical wires that connect to other parts of your system like the capacitor and compressor. If you begin to notice electrical shorts in these components, it may be the result of faulty wiring. To ensure the electricity of your system is flowing safely and properly, it’s important to have your wires checked and fixed so that your unit and all its parts can work together cohesively.
There’s no time for breaks if you’re dealing with frequent tripped breakers in your AC system. If your circuit breaker is overwhelmed by pulling too much electrical current, it can cause the breaker to trip in order to protect the entire electrical panel. This can be a strong indication of faulty wires within your system.
A Faulty Thermostat
Damaged and pinched wires can often explain a faulty thermostat, especially if it’s outdated. While your thermostat is a smaller piece of the entire AC puzzle, it deals with several electrical aspects and can wear out over time (often due to poor wiring maintenance).
Let the Wires Win
Fixing your AC wires is a win for you and your home! Faulty AC wiring can be both difficult and dangerous to detect. As cool as electricity is, it has the power to cause some serious heat in your wires and your home. Therefore, it may be smart to contact an HVAC professional to diagnose the problems with your wires — they can take care of faulty wiring as soon as possible to ensure your home is as safe as possible.
