Refrigeration Too Hot

What does Too Hot mean?

Indicates that the refrigeration temperature is 1.5º C above the compressor cut-in setting, suggesting the unit is not cooling sufficiently. This can compromise product integrity and safety.

• Refrigeration system failure to cool effectively.
• High ambient temperature affecting cooling performance.

1. 1

   Verify the accuracy of the refrigeration temperature sensor against a calibrated reference thermometer.

2. 2

   Measure the supply voltage at the compressor input terminals and verify compressor operation (audible running, vibration).

3. 3

   Inspect condenser and evaporator coils for cleanliness, obstructions, and verify proper airflow from fans.

4. 4

   Check the refrigeration unit's control parameters, specifically the compressor cut-in/cut-out temperature setpoints, against documentation.
