In this short video, the Samurai demonstrates how understanding how sealed systems work and move heat can be used to make non-invasive diagnostics on refrigerator sealed systems. In this case, we're using a design criteria for condensers called "temperature split". This is the difference between the condenser's SATURATION temperature and the ambient temperature. Saturation is the key here because you don't want the superheated or sub cooled part of the condenser for your condenser temperature.
We teach sealed system thermodynamics, operation, troubleshooting, and repair in the Refrigerator Repair course at the Master Samurai Tech Academy. Self-paced, online, on-demand 24/7.
