Diagnosis: What's Going Wrong?
During the initial service call, it was evident that the freezer was struggling to reach optimal temperatures. The compressor, condenser fan motor, evaporator fan, and suction line were all operational, yet the temperatures remained above the desired range. Further investigation revealed a low refrigerant level, indicating a leak in the system.
Repair Process: Fixing the Issue
- Installation of Piercing Valve: To assess the refrigerant level, a piercing valve was installed. This allowed for the system to be tested and confirmed the low refrigerant issue.
- Identifying the Leak: Upon closer inspection, oil stains and a visible leak at a reducing coupling were discovered. This indicated a recent leak that needed immediate attention.
- Brazing and Installation: The next step involved removing the piercing valve and installing permanent pigtails. These pigtails were brazed into place to ensure a secure and leak-free connection.
- Pressure Testing and Vacuum: After the brazing, the system was pressurized with nitrogen to check for leaks. Once confirmed leak-free, a vacuum was pulled to remove any air and moisture from the system.
- Recharging the System: With the system evacuated, it was time to recharge it with refrigerant 404A. The unit required 10 ounces of refrigerant, which was carefully measured and added to the system.
Outcome: Restoring Functionality
After the repair process was completed, the freezer was started up, and temperatures were monitored. Within a few hours, the freezer was back to its optimal temperature, ensuring that the products stored inside remained frozen and safe for consumption.
