Defrost Troubleshooting

Traulsen uses two different types of defrost on the G-Series Refrigerators. The last cabinet temperature before
the defrost started will be displayed throughout the entire defrost cycle.
1. Off-Cyle Defrost- The off-cycle defrost is really an air over defrost. In otherwords we shut off the
compressor but continue to run the Evaporator Fan Motor. During an off-cycle deforst the melting
snowflake does not illuminate but instead the fan icon. This type of defrost is time initiated every two
hours but then temperature terminated when the Evaporator Coil reaches 40 degrees fahrenheit or a
maxiuim of 30 minutes. After the coil reaches the defrost termination temperature two minutes of drip
time will begin before the compressor is energized.
