Trane Searchable Fault & Error Code Guide
| Code | Condition / Symptom | Engineering Diagnosis & Fix |
|---|---|---|
| Low Evap Temp | Evaporator saturation temperature below safety threshold | Verify secondary pump flow rate, inspect strainer, check EXV stepper drive. |
| High Temp Safety | Compressor motor winding temperature sensor exceeded safety cut-out | Inspect motor cooling suction line injection, check starter contactors, test winding resistance. |
| Starter Fault | Adaptive frequency drive or solid state starter SCR fault | Test SCR gate firing signals, check line phase balance and harmonic distortions. |
| EXV Comm Loss | Tracer controller unable to communicate with stepper valve drive module | Inspect LLID communication link wiring, replace stepper motor drive board. |
