Performance Testing

After service, verify proper operation.

1. Temperature Recovery: Set fresh food to 37°F and freezer to 0°F. Load with thermal mass (jugs of water). Temperatures should stabilize within 24 hours.
2. Defrost Cycle: Monitor. The adaptive defrost should initiate based on compressor run time and door openings, typically every 24-72 hours.
3. Ice Production:Should produce first batch of ice within 24 hours of startup. Verify ice is solid and ejects properly.
4. Dispenser Function: Test water and ice dispensing. Check for leaks.
5. Condensation Check: Ensure no condensation forms on cabinet exterior under normal room conditions.
