In order to accomplish the above our technicians fully understand how a sub-zero refrigerator system works. Both parallel circuits and series circuits in each refrigerator system in various models.
In sub-zero refrigerators and many other common refrigeration systems we have found the following sealed system failure types.
Common points of refrigerator failure
- Evaporator inlet temperature
- Refrigerator storage temp
- Condenser inlet temp
- Condenser outlet temp
- Suction line temp
- Unusual refrigerator noises
- Wattage variations
- Amperage variations
- Frost pattern
- Low side pressures
- High side pressures
- No failure at all
- refrigerant leak causing a low charge
- Partial sealed system restriction.
- Complete sealed system restriction
- Sealed system over charge
Maintenance tips:
- Ensure adequate air flow to the coil system
- Clean system regularly to ensure proper heat extraction
- Ensure door closes all the way at all times.
- Check for leaks through the gaskets.
