Electrical problems can wreak havoc on your Champaign, IL air conditioning system. Over time, components may wear out, wires can work loose and terminals start to corrode. This is especially prevalent among systems that don’t receive proper AC maintenance service from a professional HVAC technician. If your air conditioner is malfunctioning, here are three of the most common electrical issues that could be at fault.

Failing Capacitors

A capacitor is a simple device for storing an electrical charge that can be supplied whenever it’s needed. Air conditioners generally have two types of capacitors, often referred to as start capacitors and run capacitors. The start capacitor provides an electrical boost to jumpstart your unit’s blower motor. If it malfunctions, your system may not blow any air at all. Meanwhile, a pair of run capacitors supply power to the fan motor and the compressor to keep these components running. Faulty run capacitors can cause your system to perform poorly and possibly overheat.

Electrical Faults

Modern AC systems are built to be extremely rugged, but they’re not impervious to wear and tear. Electrical systems are particularly vulnerable. Wires can easily become frayed, corroded, or disconnected. Terminals and other connections are also subject to the corrosive effects of moisture and environmental exposure. Unfortunately, these issues are often tricky to diagnose. They may cause anything from poor cooling performance to a complete loss of function. Wiring issues are also a major safety hazard, so it’s important to have repairs done by a professional HVAC technician.

Tripping Circuit Breaker

If you check your home’s electrical panel, you’ll find that your air conditioner has its own dedicated circuit breaker. This is the first thing to check any time your AC suddenly stops working. A tripped breaker on rare occasions isn’t a major concern. Simply let your AC cool down for five minutes before attempting to reset the switch. If the breaker trips frequently, however, it’s time to call for AC repairs. It’s possible the breaker itself may be faulty. Alternatively, your system may be drawing too much power because of an electrical or mechanical malfunction.

It’s important to act quickly if you suspect your AC may have electrical issues. At best, it compromises your system’s performance and efficiency. At worst, it can cause serious damage and possibly present safety hazards. If you need assistance, call 217-355-9700 or explore Mattex Heating, Cooling and Plumbing’s professional AC repairs.
