Carrier 337690-401 Rubber Elbow 340155-7024 The resistor should be wired

The resistor should be wired in parallel across the input signal (+) and common (-) terminals of the actuator to drop the 4-20mA current

preventing the premature pitting and rust-through common in aftermarket alternatives

ensuring a drop-in fit for specific Aaon HVAC equipment

Failures are typically linked to refrigerant contamination or excessive vibration from misaligned piping
