Paragon Defrost Timer Wiring Diagram: Everything You Need to Know

Paragon Defrost Timer is one of the most popular and widely used devices in the refrigeration industry. It plays a crucial role in maintaining the temperature and regulating the defrost cycle in a refrigeration unit. However, installing and wiring a defrost timer can be quite challenging for beginners. In this article, we will guide you through the process of installing and wiring a Paragon Defrost Timer with a step-by-step tutorial and detailed wiring diagram.

What is a Defrost Timer?

A defrost timer is an electromechanical device that regulates the defrost cycle in a refrigeration system. It is designed to switch the defrost heater on and off at regular intervals to prevent the formation of ice on the evaporator coil. The evaporator coil is responsible for cooling the refrigerant, and any ice formation can reduce its efficiency and lead to compressor failure.

Defrost timers are available in different configurations, such as mechanical, digital, and programmable, depending on the application and requirements. The Paragon Defrost Timer is a mechanical timer that is easy to install and use.
