Description
The Carrier KAACH1701AAA is a genuine OEM crankcase heater designed to protect the compressor in compatible Carrier systems. By maintaining warmth around the compressor crankcase during off cycles, this heater prevents refrigerant from migrating into the compressor oil — a leading cause of compressor damage and premature failure.
Why Crankcase Heaters Matter
During periods of inactivity, refrigerant can migrate and mix with compressor oil. When the system restarts, this refrigerant-oil mixture can cause slugging, oil foaming, and bearing wear. A properly functioning crankcase heater eliminates this risk by keeping the compressor oil warm and refrigerant-free, extending compressor life and maintaining system efficiency.
