Description
The Carrier KAACH1601AAA is an OEM crankcase heater engineered to protect your Carrier system’s compressor from damaging refrigerant migration during off-cycle periods. By maintaining a consistent warmth around the compressor crankcase, this heater prevents liquid refrigerant from mixing with compressor oil — a leading cause of compressor failure and premature wear.
Why Crankcase Heaters Matter
During extended off cycles, refrigerant can migrate into the compressor oil sump and dilute the lubricant. When the compressor restarts, this refrigerant-oil mixture can cause slugging, bearing damage, and catastrophic compressor failure. A properly functioning crankcase heater eliminates this risk by keeping the oil warm and refrigerant-free, ensuring reliable startups and a longer compressor service life.
