Sulair compressors are equipped with diagnostic fault codes to help troubleshoot any problems that arise during operation. These codes can be divided into two main categories: general faults and component-specific faults. I will discuss both these types below in detail.

Sullair Compressor Troubleshooting

Sullair compressors are known for their reliable performance, however it is still important to be aware of the signs that may indicate a problem.

Sullair Compressor Common Issues:

Common issues that can occur with Sullair compressors include low air pressure, overheating, no airflow and Sullair compressor not starting. Lets discuss each of them and start our Sullair troubleshooting.

Low Air Pressure

If your Sullair compressor is producing low air pressure, the problem could be rooted in several different locations. The most common cause of this issue is a defective or dirty air filter. Make sure to check the condition of your air filter and if necessary, replace it with a new one. Additionally, ensure that all the hoses are in good condition and well-connected. If the air pressure is still low after these steps, contact me for further assistance.

Overheating

If your Sullair compressor is running hot, check that the vents are not blocked by dirt or dust. Additionally, inspect all the hoses to make sure they have a proper fit and are free from any obstructions. If the compressor is still overheating, check the inlet valves to make sure they are open and not stuck due to dirt or rust. You may also need to replace clogged air filters or install a larger capacity cooling system for the compressor.

No Airflow

If your Sullair compressor is not producing any airflow, it could be due to a broken switch or defective wiring. Start by checking the electrical panel in your compressor and make sure all switches are in the ‘On’ position. Additionally, inspect the main power cable for any breaks or loose connections.

Compressor Not Starting

If your Sullair compressor isn’t starting, the problem could be due to a defective starter motor. Look for signs of damage or corrosion in the starter motor and replace it if necessary. Additionally, check that all cables are connected securely and there is no blockage in the air intake.

If these steps don’t work, feel free to contact me for further help with troubleshooting your Sullair compressor.

Sullair 375 Troubleshooting:

When Sullair 375 troubleshooting, there are several common issues you may encounter.

1. No Power:

Check the connection to your power source and ensure the machine is switched on. If the circuit breaker has tripped, reset it.

2. Low or No Air Pressure:

This could be due to a leak in the air line or a problem with the compressor itself. Check the air lines for leaks and if none are found, contact a repair technician to inspect the compressor.

3. High Temperatures:

This could be due to a clogged air filter, a failed pressure switch or an overworked compressor motor. Clean the air filter regularly and inspect the pressure switch. If both of these items appear to be functioning properly, call in a repair technician as your motor may need to be replaced.

4. Compressor Not Cycling On/Off:

This could be caused by a faulty pressure switch or stuck unloader valve. Check both of these and replace them if necessary.

5. Excessive Vibrations:

This may be caused by an unbalanced compressor or loose connection on the motor. Inspect the motor mountings for any signs of wear and tear. If the problem persists, call in a repair technician as this could be an indication of a more serious underlying issue.

In addition to the common issues outlined above, it is important to regularly maintain your Sullair 375 compressor. This will help reduce the chance of any major problems from developing and also keep the machine running efficiently for longer periods of time. Regular maintenance includes changing the oil, inspecting and cleaning the air filter, and checking all connections for any signs of wear.

Additionally, be sure to check that there are no leakages in the intake or exhaust lines, as these can lead to a decrease in performance and efficiency.

By following this basic troubleshooting guide and performing regular maintenance on your Sullair 375, you can help ensure that your compressor runs smoothly for years to come.

Sullair Air Compressor Not Starting – How To Fix?

If your Sullair Air Compressor is not starting, there could be several underlying reasons. Follow these steps and do Sullair air compressor troubleshooting easily.

1. Power Supply Issues:

Verify that your Sullair Air Compressor is properly connected to a power source. Check the power cords for any visible signs of damage. Make sure the circuit breaker has not tripped. If you discover any problems with the power supply, rectify them and try starting the compressor again.

Worn out or broken belts can cause the compressor to fail to start. Replace them if needed.

Remember to always refer to your Sullair Air Compressor manual or consult with a professional if you are unsure about performing these checks and repairs.

Sullair Compressor Fault Codes:

Sulair compressors are equipped with diagnostic fault codes to help troubleshoot any problems that arise during operation. These codes can be divided into two main categories: general faults and component-specific faults.

General Faults are errors that occur when the compressor is not functioning optimally, possibly due to a lack of airflow or power supply. Examples include air-leakage faults, compressor overloads, and air pressure failures.

Component-specific Faults occur when a specific component within the compressor fails to operate properly. These could include motor faults, valve problems, oil system issues, and filter blockages.

It is important to note that Sullair compressors are also equipped with warning codes which indicate that there is an issue, but the compressor is still able to operate normally. Examples of warning codes include low oil pressure, high discharge temperature, and reduced maximum pressure.

To ensure that your Sullair compressor is running smoothly, it is important to monitor for signs of fault or warning codes on a regular basis. If a fault code appears during operation, it should be addressed immediately to avoid further damage to the compressor.

To assist with troubleshooting, Sullair provides online resources such as checklists and service manuals that provide detailed information on fault codes and their solutions. Additionally, trained technicians can be contacted for more in-depth assistance if necessary.

1. Error Code F1:

This code indicates an issue with the motor rotation. If the motor is not turning in the correct direction, it will trigger this fault code.

2. Error Code F2:

This is a temperature warning code. If the compressor is running hotter than the safe threshold, it will display this fault.

3. Error Code F3:

This code typically indicates an oil pressure problem. If the oil pressure is too low or too high compared to the set point, this fault code is displayed.

4. Error Code F4:

If the compressor is operating at a higher pressure than its rated capacity, the F4 fault code is triggered.

Please note these are common Sullair Compressor fault codes. Each fault requires careful diagnosis and should be resolved promptly to prevent further damage. It’s recommended to consult the compressor’s manual or contact a professional service for repair.
