A confirmed refrigerant-circuit or compressor finding changes which repair service is appropriate. Those categories are outside this service's stated scope.
What the observation tells you
The phrase 'not freezing' alone does not establish such a diagnosis. Written findings from a qualified assessment are more useful than a suggested part from an online discussion. Sending them early avoids arranging a visit on an inaccurate understanding of the required work.
A useful next step
Provide the report and full model reference when enquiring. The team can clarify suitability. Do not attempt a recharge, pipe test or compressor connection yourself.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
