416889 | Genuine Thermo King® Expansion Module SR2/SR3

Useful Information

Description and Purpose:

This Genuine remanufactured Expansion Module from Thermo King, which goes by Part number: 416889, is a specialized electronic component for SR2 and SR3 control systems. It serves as an add-on to the main controller, giving the system more ports to connect sensors and manage hardware. Essentially, it helps the main computer "talk" to more parts of the unit at once, ensuring every sensor and valve is working in sync to keep the environment stable. Cross reference: 41-6889

Why Replacement is Important:

When an expansion module fails, the main control system loses contact with specific sensors or parts of the equipment. This usually leads to error codes and can cause the entire system to stop working.

Impact on Vehicle Performance:

Installing a working module restores the full diagnostic and control capabilities of the electronics.
