The compressor motor has difficulty keeping up because the seals are allowing air inside the unit. Another reason may be that the containers do not allow enough airflow keeping them warmer and causing spoilage.
The thermostat is essential for maintaining the proper temperature and alerting the compressor when to click on to keep the contents cold. A failing thermostat could cause the compressor to work overtime and over chill the food. Eventually, the extra work may burn out the compressor motor.
