Electrical issues are a leading cause of compressor failures in HVAC systems. Some of the most common electrical issues include voltage fluctuations, power surges, wiring problems, and faulty contactors or relays. Voltage fluctuations can cause the compressor motor to overheat or underperform, while power surges can damage the compressor’s electrical components. Wiring problems, such as loose connections or corrosion, can also lead to compressor failure. Regular electrical maintenance, including voltage monitoring and wiring inspections, can help prevent these issues.
