What effect does a blocked condenser have on a refrigeration system?

When a condenser is blocked, it prevents the proper flow of refrigerant through the system. As a result, the refrigerant cannot effectively release heat, leading to an increase in pressure within the refrigerant lines. This increased pressure can hinder the entire refrigeration cycle, causing the system to operate inefficiently.

The blockage restricts the heat rejection process in the condenser, which is essential for maintaining the desired refrigerant pressure for optimal operation. Consequently, as the pressure in the system rises, it can lead to abnormal operating conditions which can ultimately affect the compressor performance and the overall efficiency of the refrigerator.

While the rise in system pressure is a immediate and notable impact of a blocked condenser, it also leads to secondary effects, such as increased temperatures in the evaporator and potential flooding, which significantly disrupt the balance and effectiveness of the refrigeration system. However, the initial and most direct consequence of a blocked condenser is the increase in system pressure.
