How to troubleshoot a Johnson Controls Air Compressor that won't start?
If your Johnson Controls Air Compressor won't start, check the main switch and fuses, and reset the emergency stop switch. Also, check for any alarms in the control system and reset if necessary. Finally, ensure the oil level is sufficient and charge oil if needed.
Why does my Johnson Controls Frick SGC 1913 start and then stop immediately?
If your Johnson Controls Air Compressor starts but stops immediately, it could be due to an oil system failure related to temperature, pressure, or level. Check the oil level and the valve positions.
What causes high oil filter differential pressure in Johnson Controls Air Compressor?
High oil filter differential pressure in your Johnson Controls Air Compressor is likely due to a clogged oil filter. Replace the oil filter to resolve this issue.
What to do if the Johnson Controls Air Compressor pump doesn't produce enough oil pressure?
If the pump on your Johnson Controls Air Compressor isn't producing enough oil pressure to start the compressor, check the pump rotation. Ensure the service valves are open. Inspect the filter cartridges for blockages by checking the pressure difference across the filters. Also, check the strainer for blockages and clean it if necessary. Verify that the oil pressure regulator is not set too low or stuck open, and readjust or repair it. If the pump is worn out, repair or replace it. Finally, check if the hand expansion valve may be opened too much and throttle the valve.
What causes high suction pressure and insufficient refrigeration capacity in a Johnson Controls Frick SGC 1913 Air Compressor?
High suction pressure combined with insufficient refrigeration capacity in your Johnson Controls Air Compressor can occur if the compressor protection valve is opening or leaking, so check the discharge pressure safety cut-out settings and the pilot/main protection valve. An oil return valve that is fully open can also cause this issue, so adjust the regulating valve. Finally, a clogged suction strainer can lead to these symptoms, so clean the strainer.
Why won't the capacity slide valve move on my Johnson Controls Air Compressor?
If the capacity slide valve or slide stop on your Johnson Controls Air Compressor won't move, preventing unloading/loading, it could be due to insufficient oil pressure, so check the oil pressure. The solenoid coils might be burned out, requiring replacement. Incorrect valve settings in the hydraulic system could also be the cause, so check according to the hydraulic system description. Lastly, a malfunction of the 4-way control valve of slide components could be the issue, so check according to the description of main components.
What to do if my Johnson Controls Frick SGC 1913 Air Compressor has excessive noise and vibration?
Excessive noise and vibration in your Johnson Controls Air Compressor could stem from several issues. The main oil injection valve may be closed or open too far, so open or adjust it accordingly. Bearing damage or excessive wear can also cause this, requiring bearing replacement. Additionally, the slide valve/slide stop might be out of calibration, needing calibration. A loose coupling on the shaft should be tightened or replaced if damaged. Finally, refrigerant flood back (liquid slugging) can lead to these symptoms, so correct the underlying system problem.
How to fix excessively low suction pressure in Johnson Controls Air Compressor?
Excessively low suction pressure in your Johnson Controls Air Compressor can be caused by a refrigeration load that's lower than the compressor capacity; in this case, reduce compressor capacity. It could also be due to high suction line loss, so check the valves and strainers. Another cause might be a malfunction of the evaporator, so inspect the evaporator for fouling or accumulated oil. Also, check the liquid expansion valve system, filter in the liquid line, and ensure there is sufficient refrigerant charge.
Why is the discharge pressure excessively high in my Johnson Controls Frick SGC 1913?
Excessively high discharge pressure in your Johnson Controls Air Compressor can be due to several reasons. The safety cut-out might be set too low, so check the settings of alarms and warnings. There could be high discharge line loss, so inspect the valves. A malfunctioning condenser may also be the cause; check the condenser, liquid drain, refrigerant charge, water/air inlet temperature, and water/air flow. Finally, air or non-condensable gasses in the system can cause this issue, so purge the air from the condenser side.
