Troubleshooting the high side of a refrigeration system will often give service technicians valuable information. That’s because what happens in the condenser is a direct reflection of what is happening in the rest of the refrigeration system.
Condensing temperatures, in particular, can offer useful hints as to what the problem may be within a refrigeration system. That is because almost all of the heat absorbed in the system, including the evaporator and suction line, is rejected into the condenser.
