Before Tapping into a Sealed System let’s check a few things first….

1) Gather Readings from the unit:

  • Freezer Temperature (Ideal Temp 0°F)
  • Refrigerator Temperature (Ideal Temp 37°F)
  • Compressor Amp Draw
  • Compressor Voltage

***Record the above readings for future use. If you need to call TCC for help these numbers will help the TCC Agent Troubleshoot correctly and provide correct guidance***

2) If the unit is partially cooling check for all issues that could cause a failure to cool:

  • Airflow Issues (Installation, Dirty Condenser, Food Storage, anything that can affect airflow inside or outside the unit).
  • Defrost issues.
  • Fans not operating properly.
  • Check Temp Sensor Values.
  • Check for hidden error codes.

3) Look at your Frost Pattern on the Evaporator Coils.

  • Your Frost Pattern provides very valuable information about the state of the Sealed System.
  • Ideally you would like to see an even, fully developed frost pattern covering the entire evaporator coil.
  • Click below for examples of Good and Bad frost patterns.
