Freezer Not Holding Temperature is usually one of a small number of specific, repairable causes — here's what to check and when it's worth calling a professional.
There is materially less air mass here to carry heat away, so a condenser rejects less per revolution and runs longer to reach the same cabinet temperature.
The compressor overheats compensating for restricted airflow and eventually shuts itself down as a protective measure.
Lets a steady trickle of warm, humid air into the cabinet that the compressor can never fully counteract.
Based on symptoms like this, these are the components our technicians check first. The exact part depends on your model and what we find during diagnosis.
