Excessive compressor fluid consumption in your Sullair Air Compressor may be due to: * A clogged return line; clear the orifice and return line strainer. * A lubrication system leak; check all pipes, connections, and components. * A separator element that is damaged or malfunctioning; change the separator element.
What does SSAM flash code one flash mean on a Sullair 375H Air Compressor?
If your Sullair Air Compressor displays SSAM flash code one flash, it means the compressor temperature switch is open. Check the wiring connection to the switch and tighten it if loose. Also, check the switch continuity to ground and replace if necessary. If the compressor feels hot refer to COMPRESSOR OVERHEATING trouble shooting procedure.
What does SSAM flash code three flashes mean on a Sullair Air Compressor?
If your Sullair Air Compressor shows SSAM flash code three flashes, it indicates the engine oil pressure switch is open. Check the wiring connection to the switch and tighten if necessary. Install gauge in parallel with the switch. Replace the switch if the pressure exceeds 15 psig and stays open. If the pressure is less than 15 psig, refer to the Engine Operator’s Manual.
Why is my Sullair 375H Air Compressor not achieving full discharge pressure?
If your Sullair air compressor isn't reaching full discharge pressure, it could be due to: * The run/start valve not being in the run position (for compressors with idle warm-up controls, switch the valve to RUN). * Excessive air demand (check service lines for leaks or open valves). * A dirty air filter (check the filter and change the element if required). * A defective pressure regulator (check the diaphragm and replace with a kit if necessary). * A defective idle warm-up control (replace the control).
What causes improper unloading with excessive pressure build-up in Sullair 375H Air Compressor?
Improper unloading with excessive pressure build-up in your Sullair Air Compressor can result from: * A pressure regulating valve set too high; readjust it. * A control system leak causing loss of pressure signal; check control lines. * A defective pressure regulating valve; repair the valve (kit available). * An inlet valve jammed; free or replace the valve. * A restriction in the control system; check all control lines and components for ice or other contaminants. * A defective pressure relief valve that opens when the pressure is too low; replace the pressure relief valve. * A defective pressure regulator; check the diaphragm and replace it with a kit if necessary.
What to do if my Sullair Air Compressor shows SSAM flash code one?
If your Sullair Air Compressor displays SSAM flash code one, it indicates a potential issue with the compressor temperature. Here's what you should do: * Check the wiring connection to the compressor temperature switch and tighten it if it's loose. * Check the switch continuity to ground and replace it if necessary. * Ensure the receiver tank fluid level is adequate and add fluid if needed. * Inspect the fan belt for looseness or breakage, tightening or replacing it as required. * Address insufficient cooling airflow by cleaning the fluid cooler core and ensuring proper ventilation. * Change the fluid filter element if it's clogged. * Consider changing the fluid thermostat element if it's faulty. * If the fluid cooler tube is plugged internally, replace the cooler.
How to fix Sullair Air Compressor that does not crank?
If your Sullair Air Compressor doesn't crank, it might be due to low voltage or a disconnected battery. Check the battery cables and tighten them if they are loose. Also, check the ground wire for proper attachment to the frame and tighten if required. If the battery is the issue, recharge or replace it. Another potential cause is a blown fuse in the wiring harness, so remove and inspect the fuse, replacing it if necessary.
What to do if the Sullair 375H Air Compressor engine speed is too low?
If the engine speed of your Sullair air compressor is too low, consider the following: * Check and tighten the battery cables if the battery voltage is low. * Recharge or replace the battery if necessary. * Refuel if there is no fuel. * Drain water from the fuel/water separators on the fuel filters, and siphon water from the fuel tank, cleaning the tank if necessary, if there is water or dirt in the fuel and/or filter. * Clean and replace the air filter if it is plugged. * Replace the fuel filter if it is plugged. * Check wiring and tighten all connectors, and replace the relay if the starter solenoid relay does not engage. * Check alternator 'W' terminal (7.5 ± 2.50 VAC greater than 300 HZ) if there is no input frequency from the alternator.
What causes insufficient air delivery in a Sullair 375H Air Compressor?
Insufficient air delivery in your Sullair air compressor can be caused by several factors: * The run/start valve might not be in the run position; if your compressor has idle warm-up controls, switch the valve to RUN for full operation. * A plugged air filter; replace it. * A defective idle warm-up valve; replace the valve. * A plugged air/fluid separator; replace the separator element and also change the compressor fluid and fluid filter. * A defective pressure regulator; adjust or repair it.
Why is my Sullair Air Compressor engine coolant temperature high?
Several factors can cause the engine coolant temperature to be high: * The engine coolant temperature switch may be open; check the wiring connection and tighten if necessary, or check the switch continuity to ground and replace if necessary. * Insufficient cooling airflow; clean the cooler and check for proper ventilation. * A loose or broken fan belt; tighten or replace the belt. * Low engine coolant; fill with the proper water/glycol mixture as required. * A faulty water pump; change the pump. * A defective engine thermostat; change the thermostat element.
