Which outcome occurs when an HVAC evaporator coil freezes completely during operation?

💡 Explanation

When the evaporator coil freezes solid, refrigerant liquid floods back to the compressor because boiling stops and insulating ice prevents heat absorption. Therefore, the compressor overheats owing to liquid floodback, not superheat increase, subcooling decrease or pressure elevating, which different coil conditions would produce.
