Amana-Goodman 0163R00003S Crankcase Heater 230V 40W OEM Replacement

The Amana-Goodman 0163R00003S is a genuine OEM belt-style crankcase heater rated at 230V / 40W, designed to protect the compressor in Goodman and Amana air conditioning, heat pump, and packaged HVAC systems. This direct replacement part ensures a precise fit and reliable thermal output for residential and commercial condensing units.

Crankcase heaters play a critical role in compressor longevity. During system off-cycles, refrigerant can migrate into the compressor oil, causing foaming and liquid slugging upon restart — a leading cause of compressor valve damage. This heater maintains oil temperature to prevent refrigerant migration and ensure a smooth, safe cold start.

Key Features:

• Voltage/Wattage: 230V, 40W
• Genuine OEM part from Amana-Goodman (Daikin Comfort Technologies)
• Prevents refrigerant migration into the compressor crankcase during downtime
• Keeps compressor oil in a liquid state during cold weather conditions
• Reduces risk of liquid slugging and mechanical compressor failure on startup
• Energy-efficient 40W draw provides adequate thermal protection without excessive power consumption
• Compatible with Amana and Goodman air conditioners, heat pumps, packaged units (RTUs), and furnace applications
• Rated for 230V systems only — not compatible with 115V applications

Part Numbers: OEM Part No. 0163R00003S | Alt. Part No. 0163R00003SRC | Cross Ref. No. 1121030

This crankcase heater is an essential maintenance and repair component for extending the operational lifespan of Goodman and Amana HVAC systems, particularly in climates with significant seasonal temperature variation.
