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.
