Traulsen 324-12455-00 Refrigerator Temperature Control, A30-1806

Traulsen 324-12455-00 Refrigerator Temperature Control, A30-1806

The Traulsen 324-12455-00 refrigerator temperature control, a30-1806 is a commercial replacement part identified by the manufacturer reference shown below. It switches the refrigeration control circuit according to temperature sensed by its capillary system. Correct identification matters because components that share a general appearance can differ in mounting, electrical characteristics, dimensions or operating function.

Route the capillary without kinks and place the sensing section in the original position. Verify mounting, terminals and the required temperature-control range.

Use the equipment model, serial number and existing part identification together when selecting this refrigerator temperature control. The listed specifications describe the researched reference; they do not establish universal compatibility across Traulsen equipment. Inspect the related system before ordering so a separate wiring, alignment, airflow or drainage problem is not mistaken for failure of this component.

Function & Application

This refrigerator temperature control switches the refrigeration control circuit according to temperature sensed by its capillary system. Its role should be checked against the equipment parts diagram and service documentation, including any production changes affecting the assembly.

Compatibility & Ordering Reference

A complete model compatibility list has not been established for this part. Confirm the part-number reference against the equipment parts diagram and serial-number range before ordering.

Do not assume that another part number supersedes this reference unless the equipment manufacturer documents that replacement for the specific unit.

Symptoms to Investigate

Reasons to inspect this component include inconsistent cycling, failure to respond to temperature changes, or physical damage to the sensing assembly. These symptoms are diagnostic clues, not proof that this part has failed.

Technician Diagnostic Checks

• Compare the control reference and sensing arrangement
• Inspect terminals, mounting and capillary condition
• Check sensing-element placement
• Confirm switching behavior using the manufacturer test procedure

Document the findings before replacing parts. Use the equipment service procedure and correct test equipment; component appearance alone does not establish a service diagnosis.

Before You Order

• Confirm manufacturer reference 324-12455-00 and the complete equipment model and serial number.
• Compare the existing part with the listed specifications and mounting arrangement.
• Route the capillary without kinks and place the sensing section in the original position. Verify mounting, terminals and the required temperature-control range.
• Verify whether related fasteners, fittings, keys, sensors or other service items are included or required separately.
• Confirm the supplied item and its provenance before releasing the order.

Installation & Return-to-Service Checks

Service should be performed by personnel qualified for the equipment and component. Isolate relevant power and support moving parts before disassembly. Record the original mounting, connections and routing, then follow the equipment-specific service procedure.

Confirm correct sensing placement and normal cut-in/cut-out behavior. Allow the cabinet to stabilize before judging final temperature control.

Maintenance & Related Components

During routine service, inspect the surrounding mounting points and the related components identified in the diagnostic checks. Correct the cause of wear, moisture, vibration or misalignment before fitting a replacement. Use cleaning and maintenance methods specified for the equipment and materials.
