There could be several reasons why your brand new freezer stopped working shortly after you plugged it in. Here are a few possible explanations:
Power supply issues: Ensure that the freezer is properly connected to a functional power outlet. Check if the circuit breaker or fuse associated with the outlet hasn't tripped or blown.
Temperature control settings: Make sure the temperature control dial or digital settings on the freezer are set correctly. It's possible that the temperature may have been set too high or too low, causing the freezer to shut off automatically.
Overloading or blocking the airflow: If the freezer is overloaded with food items or if there are obstructions blocking the airflow vents, it can lead to insufficient cooling and cause the freezer to stop working. Check if there is anything blocking the vents and rearrange the items inside if needed.
Malfunctioning components: While it's uncommon for a brand new appliance to have faulty components, it's not entirely impossible. There could be a malfunctioning part, such as the compressor or thermostat, that is causing the freezer to shut off. In this case, you may need to contact the manufacturer or retailer for assistance or consider returning or exchanging the freezer.
If none of these suggestions resolve the issue, it would be advisable to consult the user manual for troubleshooting steps specific to your freezer model. Additionally, reaching out to the manufacturer's customer support or contacting a professional appliance repair service can help diagnose and resolve the problem.
