SEALED SYSTEM DIAGNOSIS REVIEW

Entering and properly processing the sealed refrigeration system requires special equipment and

should only be accomplished by a qualified service technician.

Before suspecting that the sealed refrigeration system has failed, be sure to check out all other possi-

bilities as described in the following Troubleshooting Chart on pages 73-79.

There are four conditions that make entering the sealed system necessary.

1. Incorrect amount of refrigerant

2. Restriction of refrigerant flow

3. Refrigerant leak

4. Compressor not operating correctly

Current U. S. Environmental Protection Agency regulations require specific procedures and equip-

ment for the collection and disposal of any refrigerant used in the sealed system of a domestic refrig-

erator, freezer, ice machine or air conditioner. As a result, if it is determined that the sealed system

must be repaired, contact a qualified and certified service technician to perform the repairs.
