What causes burnt compressor contactors?

Burnt compressor contactors are typically caused by electrical overload, which can result from a malfunctioning compressor, dirty condenser coils, or insufficient refrigerant levels. Poor connections or loose wiring can also generate excessive heat, leading to contactor failure. Additionally, frequent cycling due to a faulty thermostat or improper system sizing can contribute to wear and overheating of the contactor. Regular maintenance and proper system diagnostics can help prevent these issues.
