16 Troubleshooting Guide

16.1. Refrigeration Cycle System

In order to diagnose malfunctions, make sure that there are no
electrical problems before inspecting the refrigeration cycle.
Such problems include insufficient insulation, problem with the
power source, malfunction of a compressor and a fan.
The normal pressure of the refrigeration cycle depends on
various conditions, the standard values for them are shown in
the table on the right.
