Carrier KAACH1401AAA Crankcase Heater

This is a genuine Carrier crankcase heater that wraps around or inserts into the compressor crankcase to keep the compressor oil warm during off-cycles. Keeping the oil warm prevents refrigerant from migrating into the crankcase and diluting the oil, which helps protect the compressor from liquid slugging and bearing wear at startup.
