Description
Carrier 0864N-0071A Crankcase Heater — 90W, 480V
The Carrier 0864N-0071A is a genuine OEM crankcase heater engineered to protect compressor longevity in commercial and residential HVAC systems. By maintaining the crankcase oil at an elevated temperature during off-cycles, this heater prevents refrigerant migration into the compressor oil — a leading cause of compressor damage, slugging, and premature failure.
Why Crankcase Heaters Matter
During extended shutdown periods, refrigerant can migrate into the compressor crankcase and mix with the lubricating oil. When the compressor restarts, this refrigerant-oil mixture can cause oil foaming and loss of lubrication, resulting in costly compressor damage. The Carrier 0864N-0071A crankcase heater keeps the oil warm enough to drive off refrigerant, ensuring clean lubrication at every startup.
