Cold rooms are common commercial equipment used to keep food fresh and hygienic. However, sometimes they malfunction and stop cooling, affecting normal use. So, what are the possible reasons why a refrigerated display case might stop cooling, and how can these be resolved? This article will introduce the common causes of refrigerated display cases not cooling and corresponding solutions.
Common Causes of chiller room Not Cooling:
Improper temperature control adjustment, refrigerator running time too short.
Temperature compensation circuit turned on or malfunctioning.
Refrigerant leakage reduces cooling capacity.
Oil blockage or dirt blockage in the piping system reduces cooling efficiency.
Fan not working.
Power contact problem.
Compressor malfunction.
Pipe blockage.
For the above reasons, you can try the following solutions:
Check if the temperature control adjustment is correct and ensure the refrigerator runs for a sufficient amount of time.
Check if the temperature compensation circuit is working properly; repair it if faulty.
Check for refrigerant leaks; add refrigerant if leaking.
Clean the piping system, ensuring there are no oil or dirt blockages affecting cooling performance.
Check if the fan is working; if not, it needs to be repaired.
Check if the power connection is normal, ensuring good power contact.
Check if the compressor is working properly; if there is a malfunction, it needs to be repaired.
Check if the pipes are blocked; if so, clear the blockage.
