Have you ever faced an error message that reads, “Compressor oil pressure difference not OK”? If so, you might wonder what it means and what to do about it. Compressors are crucial components in refrigeration systems, and any malfunction can cause significant disruptions. One such issue occurs when the oil pressure in the compressor becomes problematic. This article will dive into the causes of compressor oil pressure failures, how to address them, and why getting professional help is vital.
What Does the ‘Compressor Oil Pressure Difference Not OK’ Message Mean?
When you see the message “Compressor oil pressure difference not OK”, it indicates that one of the oil pressure monitoring switches has detected a problem. These switches are designed to monitor the oil pressure inside the compressor, ensuring it stays within the correct range for proper operation.
This message appears because the switch has cut out due to an oil pressure issue. As a safety measure, the compressor is switched off automatically to prevent further damage. So, when you encounter this message, it’s important not to ignore it.
Role of Oil Pressure Monitoring Switches
Oil pressure monitoring switches play a critical role in protecting the compressor. They constantly measure the pressure levels and act as a safeguard. When oil pressure drops below the safe threshold, the switch activates, cutting off the compressor to avoid further damage.
If the oil pressure isn’t corrected promptly, it can cause overheating and damage to the compressor, leading to expensive repairs or replacements.
Consequences of Compressor Switch-Off
When the compressor is automatically switched off, it impacts the entire refrigeration system. This can result in reduced cooling efficiency or, in some cases, a complete halt in operation. A switched-off compressor means no circulation of refrigerant, which can lead to temperature inconsistencies in stored products.
Acknowledging and Resetting the Failure
Once the oil pressure switch cuts out, you need to acknowledge the failure and reset the system manually. To do this, wait for the bimetallic trigger in the switch to cool down. Once cooled, press the unlocking button located in the switch casing. This resets the switch and allows the compressor to restart—if the underlying issue has been resolved.
Location of the Oil Pressure Switch
The oil pressure monitoring switch is typically located beside the compressor. You’ll find it mounted within the compressor’s casing, making it accessible for resetting when necessary. If you’re unsure, consult the user manual or a technician to confirm its exact location.
Common Causes of Compressor Oil Pressure Failures
Several factors can trigger the oil pressure switch, causing the “Compressor oil pressure difference is not OK” message. The two most common causes include:
Causes of Compressor Oil Pressure Difference Failure
A common cause for compressor oil pressure issues is a lack of oil in the crankcase of the compressor. This is often overlooked, but it’s critical for proper functioning. Too little oil results in increased friction and eventually causes the compressor to shut down.

- Lack of oil in the crankcase
- Foaming of oil due to the presence of refrigerant
Lack of Oil in the Crankcase: A Deeper Look
Oil in the compressor crankcase is vital for smooth operation. Without enough oil, the compressor can’t maintain proper lubrication, which leads to increased friction and overheating. Over time, this lack of lubrication can cause serious mechanical damage.
Several reasons can lead to low oil levels, including leaks, poor maintenance, or excessive consumption of oil by the system.
Foaming of Oil: Causes and Implications
Oil foaming is another culprit behind compressor oil pressure issues. This happens when refrigerant mixes with the oil inside the crankcase, creating bubbles. These bubbles reduce the oil’s lubricating ability and cause inaccurate oil pressure readings. If left unchecked, foaming can lead to significant wear and tear on the compressor, reducing its lifespan.
Addressing Oil Foaming in Compressors
Foaming can occur when refrigerant mixes with the oil, leading to improper lubrication and irregular oil pressure. This could lead to system inefficiencies or even failures, especially in high-demand equipment like freeze-dryers.

Preventative Maintenance for Avoiding Oil Pressure Issues
Regular maintenance is the key to preventing compressor oil pressure problems. Ensure that oil levels are checked frequently and topped up as needed. Additionally, be vigilant about preventing refrigerator leaks, which can contaminate the oil and lead to foaming.
Preventing Future Compressor Failures
Regular maintenance and inspections are essential to ensure that compressor oil levels are maintained and that the oil is in good condition. Proactively managing issues like oil pressure and contamination can prevent expensive downtime.

Routine oil analysis can also help detect contamination early, allowing you to address the issue before it causes major damage.
The Role of a Refrigeration Expert
If the error message persists or you’re unsure about how to fix the issue, it’s time to call in a refrigeration expert. These professionals are trained to diagnose and repair oil pressure problems effectively. Trying to fix the issue on your own could worsen the problem or even void the equipment warranty.
Troubleshooting Oil Pressure Problems
One way to troubleshoot this failure is by inspecting the oil level and the oil condition itself. Sometimes, the oil foams due to refrigerant mixing into it, causing disruptions in oil pressure. Such complications also occur in systems where vacuum levels are crucial. If you’re facing related issues in freeze-dryers, explore our insights on freeze dryer leak detection and how to mitigate similar faults.
While it’s best to leave complex repairs to experts, there are a few basic troubleshooting steps you can take:
- Check oil levels and top up if necessary.
- Inspect for refrigerant leaks.
- Ensure the oil pressure switch is functioning properly.
If these steps don’t resolve the issue, contact a technician.
How to Regularly Monitor Compressor Oil Pressure
Monitoring compressor oil pressure is critical for preventing failures. Use pressure gauges or advanced monitoring systems to keep an eye on the oil pressure regularly. Smart sensors and automated alerts can help you stay ahead of potential issues, giving you peace of mind that your system is running smoothly.
Long-Term Impacts of Ignoring Oil Pressure Failures
Ignoring oil pressure failures can lead to disastrous consequences. Prolonged low oil pressure can cause the compressor to overheat, leading to component failure and costly repairs. In worst-case scenarios, the entire compressor may need replacement, which can be a significant expense for any business.
Conclusion
Maintaining proper oil pressure in your compressor is vital for the health of your refrigeration system. The “Compressor oil pressure difference is not OK” message is a warning sign that should never be ignored. By understanding the causes and addressing them promptly—whether through regular maintenance or professional assistance—you can prevent costly damage and keep your refrigeration system running efficiently.
Summary:
Compressor oil pressure difference not ok: A refrigeration expert must be called to eliminate this failure. This failure message appears when one of the oil pressure monitoring switches has cut out. The corresponding compressor was switched off. After the bimetallic trigger in the switch has cooled down, this failure must be acknowledged by pressing an unlocking button installed in the switch casing. This switch is located beside the compressor. The causes of this failure could be: Lack of oil. There is too little oil in the crankcase of the corresponding compressor.
