York (Johnson Controls) Searchable Fault & Error Code Guide
| Code | Condition / Symptom | Engineering Diagnosis & Fix |
|---|---|---|
| High Disch Pressure | Water-cooled condenser head pressure exceeded safety limit | Descale condenser tube bundle, verify cooling tower basin flow and pump impeller. |
| Oil Flow Lockout | Compressor lubrication differential pressure below threshold | Replace clogged oil filter element, inspect oil pump, check oil heater operation. |
| Low Evap Temp | Evaporator refrigerant saturated suction temperature below freeze point | Check chilled water flow rate, clean paddle switch, inspect TXV/EEV capacity control. |
| Microprocessor Trip | OptiView processor analog input signal lost or communication timeout | Test transducer 4-20mA loop signals, inspect terminal ribbon bus connectors. |
