Exam Details

The Colorado Denver Refrigeration Operator (ICC 228_CO_D) exam is a trade-focused examination for candidates preparing to demonstrate refrigeration operator knowledge. The exam is associated with refrigeration operation, electrical awareness, mechanical code understanding, equipment components, controls, safety concepts, system operation, and practical refrigeration knowledge used in the field.

This exam preparation package is built for candidates who need a structured way to study the listed references. The three books serve different purposes during preparation. NFPA 70: National Electrical Code, 2014 Edition supports electrical code topics. International Mechanical Code, 2015 supports mechanical system and code-related topics. Modern Refrigeration and Air Conditioning, 22nd edition supports refrigeration theory, system operation, equipment function, controls, service concepts, and troubleshooting fundamentals.

Because the exam is open book, candidates should prepare by practicing how to move through the books efficiently. Open-book testing does not remove the need for study. Instead, it adds another skill: reference navigation. You need to recognize when a question is asking about an electrical topic, when it is asking about a mechanical code topic, and when it is asking about refrigeration theory or equipment operation.

A productive study plan should include reading, topic review, lookup practice, and timed question practice. Candidates should become familiar with each book’s table of contents, index, chapter structure, headings, definitions, and common terminology. The better you understand the layout of each reference, the more confident you can feel when searching for information during the exam.

Open Book Test

The Colorado Denver Refrigeration Operator (ICC 228_CO_D) exam is an open-book test. This means candidates may use approved reference materials during the exam, but it does not mean the exam should be approached casually. Open-book exams are often challenging because they test your ability to understand the question, select the correct reference, locate the applicable information, and apply it within the available testing time.

For open-book preparation, one of the most important skills is knowing which book to use first. Electrical questions may lead you to the National Electrical Code. Mechanical system or code-based questions may lead you to the International Mechanical Code. Refrigeration operation, components, cycle theory, service procedures, and troubleshooting questions may lead you to Modern Refrigeration and Air Conditioning. Building this habit before the exam can help you avoid wasting time in the wrong reference.

Students should practice with the actual books included in this package. Review the indexes, learn common keywords, and become comfortable moving between major sections. During study sessions, read a question, identify the topic, choose the likely book, locate the supporting information, and then answer. Repeating that process helps build the rhythm needed for an open-book exam.

It is also important to avoid relying only on memory. Memorization can help with familiar concepts, but open-book exams often require precise information. Candidates should learn how to confirm answers in the references instead of guessing. The goal is to combine knowledge with efficient lookup skills so that you can answer with confidence and manage your time effectively.

Licensing Steps

Candidates preparing for the Colorado Denver Refrigeration Operator exam should follow the current licensing and testing instructions that apply to the ICC 228_CO_D exam and the Denver refrigeration operator credential. The exam-preparation process should begin by confirming that this is the correct exam for the license or certification goal being pursued.

After confirming the correct exam, candidates should gather the required study references and create a realistic preparation schedule. This Ultimate package supports that step by providing rental access to the listed books and 1 year of course access. The extended course access period allows students to review at a manageable pace, revisit difficult topics, and practice open-book navigation over time.

A good licensing preparation plan should include both study tasks and administrative tasks. Study tasks include reviewing electrical, mechanical, and refrigeration concepts; practicing book lookups; and working through course material. Administrative tasks may include reviewing application requirements, preparing documentation, following testing registration instructions, and completing required licensing steps.

Application Service is included with this package, giving students additional support beyond study materials. While the course and books support exam preparation, the Application Service helps make the overall process more organized.

As the exam date approaches, candidates should focus on final review. That means reviewing weak areas, practicing timed lookups, becoming familiar with reference organization, and reducing uncertainty about where information is located. A steady preparation process is usually more effective than last-minute cramming, especially for open-book exams involving multiple references.
