Adding refrigerant would have fixed this refrigerator…
For about a week.
The customer, Mr. Miller, called because his Frigidaire had stopped cooling and he thought it might be time for a replacement.
After carrying out a full sealed system diagnosis, I confirmed the problem wasn’t the compressor.
The system had lost refrigerant because of a leak hidden in the Yoder loop.
The Yoder loop is tubing built into the cabinet that helps prevent condensation around the doors. Once it develops a leak, refrigerant slowly escapes until the refrigerator can no longer cool.
To restore the refrigerator, I:
• Recovered the remaining refrigerant.
• Cut out and bypassed the leaking Yoder loop.
• Installed a new filter drier.
• Pressure-tested the sealed system.
• Pulled a deep vacuum to remove air and moisture.
• Recharged the system with the factory-specified refrigerant charge.
After final testing, the refrigerator was back to normal operating temperatures and performing as it should.
This is why I never recommend simply “adding gas.”
If the leak isn’t repaired, the refrigerant will escape again. The real repair is finding the source of the leak and correcting it properly.
I want to say a sincere thank you to Mr. Miller for trusting Cold Masters with the repair of your refrigerator. We truly appreciate the opportunity to earn your business, and we’re glad we could save your refrigerator and help you avoid the cost of replacing it.
