Fail-Safe Operation: Mechanical spring return ensures the damper returns to a known safety position upon loss of control air pressure

Contractors favor this model for its HVAC system diagnostics compatibility and ease of field integration

Always verify the wiring schematic on the unit's access panel to ensure proper communication between the IFC and the motor module

Durable Construction: Built with heavy-duty materials to withstand high-temperature flue environments

The close on rise switch action—meaning contacts close as the temperature increases—allows for direct control of compressors or refrigerant solenoid valves without the immediate need for auxiliary relays in many line voltage configurations

York 371-05506-002 Oil Pump Kit 319852-301 Fail-Safe Operation: Mechanical spring returnThe York 371 05506 002 Oil Pump Kit is a critical service replacement for 460V York semi hermetic compressors found in large tonnage commercial HVAC refrigeration and packaged rooftop units. This kit, which serves as the direct cross for 024 36133 002, is engineered to maintain precise oil differential pressure across the lubrication circuit. When diagnosing low oil pressure alarms or increased mechanical noise, this 460V oil pump is the standard
