Commercial True Refrigerator Error Code E3 or P3

If your Commercial True refrigerator displays the E3 (or P3) error code, it signifies an issue with an auxiliary or display probe. These probes play a crucial role in monitoring various aspects of your refrigerator’s performance, ensuring optimal operation and food safety. However, when a probe malfunctions, it can lead to inaccurate readings and potentially affect the functionality of your refrigerator.

Understanding the Auxiliary and Display Probes:

• Auxiliary Probe: This probe might be responsible for monitoring specific areas within the refrigerator, such as the defrost cycle, the condenser coil, or the cabinet temperature.
• Display Probe: This probe specifically monitors the temperature displayed on the control panel and ensures its accuracy.

Potential Causes of E3 (P3) Error Code:

• Faulty probe: The probe itself might be malfunctioning due to internal component failure, age-related wear and tear, or physical damage.
• Wiring issues: Loose or damaged wiring connections between the probe and the control board can disrupt communication and lead to inaccurate readings.
• Control board malfunction: In rare cases, the control board responsible for processing the probe data might be malfunctioning and misinterpreting the signal.

DIY Solutions

• Check the control panel: Ensure the displayed temperature reflects the actual temperature within the refrigerator. If there’s a significant discrepancy, suspect a probe issue.
• Visually inspect the probes: Look for any visible signs of physical damage on the probes or their wiring connections.
• Clean the probes: Gently clean the probe surfaces with a soft, damp cloth to remove any dust or debris that might interfere with readings.

Important Considerations:

• DIY solutions are limited: While the above steps can provide initial checks, it’s highly recommended to seek professional assistance for diagnosing and repairing the E3 (P3) error code.
• Qualified technicians possess the expertise and tools to accurately diagnose the faulty component (probe or control board) and perform the necessary repairs safely and effectively.
• Ignoring the E3 (P3) error code can lead to further problems, such as improper cooling, defrost cycle malfunctions, and inaccurate temperature readings, potentially compromising food safety and increasing energy consumption.
