AC Problems Caused by Electrical Failures

hvac-technician-repairing-air-conditionerDirty air filters, refrigerant leaks, frozen coils… These are the usual suspects of air conditioner problems that can wreak havoc on your air conditioner. But what happens if you’ve done some of your own inspections and found the problem is none of these things?

It could be due to something you won’t be able to spot easily: a faulty electrical component.

Of course, we’d recommend first that you call for professional¬†air conditioning repair service in Riverside, CA if it gets to that point; electrical problems bring a serious risk of injury or even death if not handled properly. That being said, read on to learn about the potential issues electrical failures can bring.

Thermostat Problems

Thermostats have very few moving parts, and this makes them prime targets for the subject of do-it-yourself replacement articles on the internet. However, if you don’t know much about electrical work, the wiring aspect of thermostat replacement could prove troublesome. Any number of things could go wrong with the wiring, like missing insulation, a failed connection, or broken and pinched wires.

Given that the thermostat is the brain or control system of the AC, faulty wiring in thermostat will compromise the rest of the system, possibly causing your system to turn off randomly or even run for longer than it should.

Failing Capacitor

The capacitor is a battery that stores electricity, and it’s essential for powering up components that need a stronger jolt of power. The fans in the outdoor and indoor units are two examples of motors that require a boost from the capacitor. Therefore, if you turn on your AC one day to find that the system is stuttering or has difficulty starting or staying on, a failing capacitor is a potential reason. You also might hear a clicking noise from the capacitor before it fails for good.

Even if the capacitors are down, the system will still try to start those motors, and that can lead to them burning out very quickly. Make sure to call in a professional before it gets to that point.

Faulty Connections

This is a general electrical problem that can happen anywhere in your air conditioner. In some cases, it could be as simple as wiring that has gone bad. Wear-and-tear can cause wires to fray or corrode, and wires may disconnect if an unqualified person has tampered with the electrical work. Finding the source of faulty wiring is not safe for an amateur, so don’t attempt to investigate it on your own.

Faulty connections can also be caused by something like a blown fuse. Since fuses are designed to protect the system from overcurrent, a blown fuse suggests that there’s a deeper issue concerning the electrical components or wiring. Replacing the fuse without having a professional look for the underlying problem will just cause the problem to repeat itself again, so it’s best not to ignore this warning sign.
