Description
The Copeland 918-0103-00 is a 240-volt Crankcase Heater (CCH) Kit engineered to protect Copeland compressors from the damaging effects of refrigerant migration during off-cycle periods. By maintaining the compressor oil at an elevated temperature, this crankcase heater prevents liquid refrigerant from mixing with the lubricating oil — a leading cause of compressor damage and premature failure on startup.
Why Crankcase Heaters Matter
During extended off cycles, refrigerant can migrate into the compressor crankcase and dilute the oil. When the compressor restarts, this refrigerant-oil mixture can cause slugging, oil foaming, and bearing wear. Installing a properly rated crankcase heater is a critical preventive measure recommended for most residential and light commercial refrigeration and air conditioning systems.
