Traulsen 337-60447-00 Coil Defrost Temperature Sensor Replacement, 12-Month Warranty

Restore dependable defrost temperature monitoring with the Wholesale Sensors Replacement for Traulsen 337-60447-00 Coil Defrost Temperature Sensor.

Designed as an OEM-style aftermarket replacement for compatible Traulsen commercial refrigeration equipment, this sensor monitors evaporator coil temperature and provides feedback to the electronic refrigeration controller.

Commercial refrigerators and freezers depend on properly functioning defrost systems to manage frost accumulation and maintain cooling efficiency. When an original coil temperature sensor becomes damaged or electrically defective, the equipment may experience inaccurate temperature readings, excessive frost buildup, or defrost-related controller faults.

Replacing a confirmed defective sensor may help restore normal defrost monitoring without replacing unrelated refrigeration components.

Product Specifications

Compatible Traulsen Refrigeration Equipment

The Traulsen 337-60447-00 coil defrost temperature sensor is intended for select commercial refrigeration equipment requiring this specific original equipment component.

Potential applications include compatible:

• Traulsen commercial refrigerators
• Traulsen commercial freezers
• Traulsen reach-in refrigeration equipment
• Traulsen refrigerated storage cabinets
• Traulsen electronic defrost control systems

Compatibility depends on the equipment’s complete model number, serial number, refrigeration controller, and original sensor specifications.

Before ordering, consult the manufacturer’s parts diagram or service manual to confirm the correct replacement number.

Compare the original sensor with the replacement to verify probe dimensions, resistance characteristics, cable length, and electrical connections.

Important: This sensor is not universal across all Traulsen refrigeration equipment.

How the Traulsen 337-60447-00 Coil Defrost Sensor Works

The Traulsen 337-60447-00 coil defrost temperature sensor monitors temperature conditions at the evaporator coil.

The sensor provides temperature-dependent electrical feedback to the compatible refrigeration controller.

Depending on the equipment design, the controller uses this information to monitor coil temperature and determine when a defrost cycle should end.

When the original sensor becomes damaged or electrically defective, the controller may receive inaccurate or interrupted temperature information.

Replacing a defective coil defrost sensor may help restore the intended defrost monitoring function.

This component is a temperature sensor, not a defrost heater, compressor, refrigeration controller, or complete defrost system.

Coil Temperature Monitoring and Sensor Construction

The Wholesale Sensors replacement for Traulsen 337-60447-00 is intended for compatible commercial refrigeration defrost sensing applications.

Important installation considerations include correct temperature sensing characteristics, matching probe configuration, proper evaporator coil placement, secure electrical connections, and appropriate cable routing.

Correct installation helps maintain dependable coil temperature feedback during refrigeration and defrost operation.

Specific sensor resistance values, probe materials, cable length, connector configuration, and operating temperature ratings should be confirmed against the product’s engineering documentation.

Helps Resolve Common Traulsen Defrost Problems

A damaged or defective coil defrost temperature sensor may contribute to:

• Excessive evaporator frost or ice buildup
• Improper defrost termination
• Inaccurate evaporator coil temperature readings
• Extended or interrupted defrost cycles
• Intermittent temperature sensor signals
• Open or shorted sensor circuit faults
• Refrigeration controller warnings
• Reduced cooling performance caused by defrost problems

Replacing the Traulsen 337-60447-00 defrost temperature probe may help resolve these issues when the original sensor is responsible.

Similar symptoms can result from defective defrost heaters, refrigeration controllers, evaporator fans, airflow restrictions, or other equipment faults.

Proper diagnosis is recommended before replacing components.

Traulsen Error Codes and Troubleshooting

Depending on the refrigeration model and installed controller, a defective coil defrost sensor may trigger temperature sensor warnings, open-circuit indications, short-circuit indications, or defrost-related faults.

Exact diagnostic codes vary by equipment model and controller.

Commercial refrigeration equipment does not use standardized automotive OBD-II diagnostic codes.

Consult the Traulsen service manual for model-specific troubleshooting procedures.

Installation and Replacement Instructions

Disconnect electrical power before servicing the refrigeration equipment.

Locate the original coil defrost sensor using the manufacturer’s service documentation.

Record the existing sensor position, mounting arrangement, wiring connections, and cable routing.

Compare the replacement Traulsen 337-60447-00 sensor with the original component.

Confirm the replacement matches the required sensor specifications and electrical connections.

Remove the defective sensor according to the manufacturer’s instructions.

Install the replacement in the designated evaporator coil sensing location.

Secure the sensor and route its wiring according to the original equipment configuration.

Restore equipment operation and verify coil temperature monitoring and defrost behavior using the manufacturer’s recommended testing procedures.

Safety Notice: Never bypass refrigeration safety controls or electrical protection devices.

Professional installation by a qualified commercial refrigeration technician is recommended.
