8145-00 - Genuine OEM Robertshaw Electromechanical Defrost Timer, 120V

8145-00 – Genuine OEM Robertshaw Electromechanical Defrost Timer, 120V

The 8145-00 Genuine OEM Robertshaw Electromechanical Defrost Timer, 120V is an original manufacturer replacement component designed for commercial refrigeration applications, including commercial freezers and refrigerators. Manufactured by Robertshaw under the trusted Paragon® 8000 Series, this timer automatically initiates and manages defrost cycles to help maintain efficient cooling performance and prevent excessive frost accumulation. Available from Appliance Kingdom, this genuine OEM refrigeration part ships across Canada with fast and reliable delivery.

A properly functioning defrost timer is critical to maintaining consistent refrigeration temperatures, energy efficiency, and evaporator performance. When a defrost timer fails, frost buildup can restrict airflow, reduce cooling capacity, and potentially lead to costly equipment downtime. Replacing a faulty timer with a genuine OEM Robertshaw component helps restore dependable operation and long-term reliability.

What Does the Defrost Timer Do?

The defrost timer controls when a refrigeration system enters and exits its defrost cycle. During normal operation, frost naturally accumulates on the evaporator coil. The timer periodically initiates a defrost cycle, allowing the system to remove accumulated frost and maintain proper airflow and cooling efficiency.

The Robertshaw 8145-00 is a heavy-duty electromechanical control designed for commercial refrigeration environments. It supports electric defrost heaters, hot gas defrost systems, and compressor-off-cycle defrost applications. OEM specifications are important because timing accuracy and switching reliability directly affect refrigeration performance and equipment longevity.

When a defrost timer begins to fail, frost buildup may increase, cooling efficiency may decline, and refrigeration equipment may struggle to maintain proper temperatures.

Common Symptoms Indicating Replacement

A defective defrost timer may contribute to the following refrigeration issues:

• Excessive frost or ice buildup on evaporator coils
• Reduced cooling performance
• Refrigerator or freezer temperatures rising unexpectedly
• Defrost cycle not initiating properly
• Defrost cycle remaining active too long
• Compressor running excessively
• Restricted airflow inside the cabinet
• Inconsistent product temperatures
• Equipment downtime caused by frost accumulation

If the timer has been diagnosed as faulty, replacing it often restores proper defrost scheduling and refrigeration performance. Similar symptoms can also be caused by failed heaters, termination controls, sensors, or wiring issues, so proper diagnosis is recommended before replacement.

Compatibility Guidance

This component is designed for commercial refrigeration equipment, including compatible commercial refrigerators and freezers that utilize Paragon/Robertshaw defrost controls.

Before ordering:

• Verify the equipment model number.
• Confirm the existing timer part number.
• Review electrical requirements and control configuration.
• Contact Appliance Kingdom for compatibility assistance if needed.

Accurate verification helps ensure proper installation and performance.
