Thermo King 41-2997 Controller

The Thermo King 41‑2997 is a cab‑mounted LCD controller for V‑280 truck refrigeration units, providing temperature monitoring and remote control of the unit’s compressor and fan. Common failure modes reported on this model include power supply board faults (brown‑out or intermittent operation), display backlight failures, and loss of communication with the main control module due to damaged serial cables or connector corrosion. Initial diagnostics should verify 12 V input stability, inspect all connectors for corrosion or loose pins, and check the controller’s diagnostic LEDs or error codes for indications of a power‑board or communication fault.[oss-gpt-20b] Post Comment
