3. Installation and Setup
This temperature sensor is designed for specific Traulsen refrigeration models. Installation typically involves replacing an existing sensor. Follow these steps carefully:
- Safety First: Before beginning any installation or replacement, ensure the equipment is completely powered off and disconnected from its power source to prevent electrical shock.
- Locate Existing Sensor: Identify the faulty or old temperature sensor within your Traulsen unit.
- Disconnect Old Sensor: Carefully disconnect the 2-pin connector of the old sensor. Note the routing of the wire.
- Remove Old Sensor: Detach the old sensor from its mounting location.
- Install New Sensor: Position the new TRAULSEN 337-60406-02 sensor in the same location as the old one. Ensure the 3/4-inch black sensor end is properly situated for accurate temperature readings.
- Connect New Sensor: Connect the new sensor's 2-pin connector to the corresponding receptacle in the unit. Ensure a firm and secure connection.
- Route Wiring: Route the 74-inch blue wire carefully to avoid pinching or damage.
- Test Functionality: Once installed, restore power to the unit and monitor its operation to confirm the new sensor is providing accurate temperature readings.
Note: While this sensor is a direct replacement for many applications, always verify the connector type and specifications against your unit's requirements. Some older units may have different connector styles, requiring adaptation.

4. Operation Guidelines
The TRAULSEN Coil Temperature Sensor operates passively by detecting the temperature of its environment and transmitting this data to the refrigeration unit's control system. It does not require direct user interaction for its function. Once properly installed, the sensor continuously monitors the coil temperature, allowing the unit to regulate its cooling cycles efficiently. Ensure the sensor tip remains free from obstructions or excessive ice buildup for optimal performance.
5. Care and Maintenance
To ensure the longevity and accuracy of your TRAULSEN Coil Temperature Sensor, consider the following maintenance guidelines:
- Regular Inspection: Periodically inspect the sensor and its wiring for any signs of physical damage, wear, or corrosion.
- Cleanliness: Keep the sensor tip clean and free from dust, debris, or ice accumulation, which can affect its accuracy. Use a soft, damp cloth for cleaning; avoid abrasive materials or harsh chemicals.
- Secure Connections: Verify that the 2-pin connector remains securely attached and that the wire is not pinched or strained.
- Avoid Extreme Conditions: While designed for refrigeration environments, avoid exposing the sensor to temperatures beyond its operational range or to direct physical impact.
6. Troubleshooting Common Issues
If your refrigeration unit is displaying incorrect temperature readings or fault codes related to the coil temperature, the sensor may be a contributing factor. Consider the following troubleshooting steps:
- Inaccurate Readings: If the unit displays temperatures that seem incorrect, first check the sensor's physical placement and ensure it is not obstructed or covered. Verify the connector is fully seated.
- Sensor Not Detected/Fault Code: If the unit indicates a sensor error, check the integrity of the wiring from the sensor to the control board. Look for cuts, breaks, or loose connections.
- Intermittent Issues: Intermittent problems can sometimes be caused by a faulty connection or a sensor that is beginning to fail.
Recommendation: If troubleshooting steps do not resolve the issue, and the sensor is suspected to be faulty, replacement is typically the next step. Ensure the replacement sensor matches the specifications and connector type of the original part.
