York S1-025-33326-000 Crankcase Heater

Protecting your compressor from liquid slugging and refrigerant migration during the off-cycle requires a reliable thermal solution. The York S1-025-33326-000 Crankcase Heater is a heavy-duty insertion type heater designed to maintain lubrication viscosity in York and Bristol compressor applications. Engineered with a broad 100-600V range and a 30-watt output, this component provides the critical heat needed to keep refrigerant out of the oil, preventing flooded starts that lead to premature mechanical failure. This model features a 3/4-inch diameter and a 1 1/4-inch insertion length for a precise fit into the heater well, ensuring maximum surface contact and heat transfer. The 48-inch leads provide ample length for clean routing to the contactor or control board. As any veteran tech knows, a failed heater is a common culprit for tripped breakers; replacing a worn element with this HVAC OEM replacement part is essential for system longevity in cold-weather environments and year-round heat pump service.

• Universal Voltage Compatibility: Hardwired for 100 to 600 Volts, making it a versatile stock item for various job sites.
• Optimized Compressor Protection: Maintains oil temperature to prevent refrigerant dilution and ensures smooth compressor start-up.
• Precision Insertion Design: The 3/4" diameter ensures a snug fit in high-performance Bristol and York compressor wells.
• Durable Construction: Built to withstand constant thermal cycling without degradation of the heating element.
• Long Lead Length: Includes 48-inch wiring leads for easier termination in complex electrical cabinets.

• How do I test if my crankcase heater is failing? Use a multimeter to check for continuity across the leads; an "open" reading typically indicates a broken internal element.
• Is this compatible with multiple York models? Yes, this 30W crankcase heater is a standard replacement for many York and Bristol configurations requiring a 3/4-inch insertion element.
• When should the heater be energized? In a standard sequence of operation, the heater should be energized during the compressor's "off" cycle to maintain oil temperature.
