Morse GCRS-40-40 troubleshooting: 8 fault codes and symptom-cause-remedy entries from the manufacturer's own service documentation.
Morse GCRS-40-40 — full specs, parts & maintenance.
| Symptom | Cause | Remedy |
|---|---|---|
| UNPLANNED SHUTDOWN | Compressor oil is not at proper level, oil cooler has dirt, slush, ice on the fins, broken hose, broken oil lines, loose or broken wire. | Check compressor oil level, clean oil cooler, inspect external components for damage. |
| IMPROPER DISCHARGE PRESSURE | Too much air demand, service valves open, leaks in service line, restricted compressor inlet air filter, faulty control system operation, low engine speed. | Check and address the issues listed under 'too low' and 'too high' discharge pressure scenarios. |
| BLOWDOWN VALVE | Automatic blowdown valve inoperative, blockage in air line from compressor to blow down valve, orifice at blowdown clogged. | Check and clear the issues listed. |
| ENGINE OVERHEATING | Low oil level, air blockage into engine fan, air blockage from fan exhaust side of engine, dirty oil in engine, low engine coolant level. | Refill oil if necessary, clear any blockages, ensure proper cooling system function. |
| ABNORMAL COMPRRESSOR OIL CONSUMPTION OR OIL IN SERVICE LINE | Over filling of oil sump, leaking oil lines or oil cooler, defective separator element, compressor shaft seal leakage, discharge pressure below 55 PSI. | Check and address the issues listed. |
| SEPARATOR PLUGGING | Foreign material entering the compressor inlet or compressor oil breaking down or excessive breakdown. | Not explicitly stated, but implies checking for foreign materials and ensuring proper oil condition. |
| High compressor discharge temperature | 1. Check compressor oil level. Add oil if required (see section for oil specifications). 2. Check engine fan and fan belt. 3. Clean outside of oil cooler. 4. Clean oil system (cooler) internally. 5. Plugged compressor oil filter. Change element. 6. Plugged oil return line, clean orifice and check valve. | |
| Insufficient air delivery | 1. Plugged compressor air filter, clean or replace. 2. Plugged air/oil separator. Replace separator element and also change compressor oil and oil filter at this time. 3. Defective pressure regulator, adjust or repair. |
