COMING SOON This Module focuses on Understanding Fridge/Freezers and Basic Diagnosis This module gives a break down guide to how the units work, how food is cooled and what components generally make up their various designs. We will draw your attention now to the fact that the modern fridge freezer uses R600A gas and when the refrigerant system is compromised in anyway, unfortunately repairs are considered by most Beyond Economical Repair. This module will help with the diagnosis of such faults and the repair of others, but unfortunately the modern system is not designed for longevity. Please be aware that under no circumstances should you be performing "live testing" which means at not point should you be exposed to live electrics outside basic operations during this course.
