Final answer:
When replacing a burnt compressor, the compressor itself is changed, along with related components such as the filter drier and refrigerant. Electrical connections may also require attention, and the system is evacuated, tested for leaks, recharged, and tested for performance.
Step-by-step explanation:
When changing out a burnt compressor in a refrigeration or air conditioning system, several components are typically addressed. The most crucial change is the compressor itself, but other parts are also likely to be replaced or serviced. These include the filter drier, which removes contaminants and moisture from the system, and the refrigerant, which may be recovered, recycled, or replaced. Electrical connections and wiring may also need repair or replacement if damaged. The system will be evacuated and a vacuum test performed to ensure there are no leaks. After installing the new compressor and other new components, the system is recharged with refrigerant, and performance is tested to verify that the issue has been resolved.
