The buzzing sound and the chemical-type smell are indicators that something might be wrong with the refrigerant or the compressor.
When the refrigerator's cooling system fails, it won't be able to maintain the cold temperatures needed to keep your food safe. The fact that the items in both the refrigerator and freezer were not cold is a concerning sign.
In this situation, it's essential to take the following steps:
Safety first: Since you mentioned feeling a bit uneasy and there was a chemical smell, it's crucial to prioritize your safety. If you suspect a potential gas leak or any hazardous situation, evacuate the area and contact a professional appliance repair technician immediately.
Check food safety: As for the food, it's challenging to determine whether it's safe to eat without knowing how long the refrigerator has been without proper cooling. If the food has been at room temperature for an extended period, it's best to err on the side of caution and consider it unsafe for consumption.
Inspect the refrigerator: You might want to unplug the refrigerator and examine it for any visible issues like leaks, unusual sounds, or burning smells. However, refrain from trying to repair it yourself, as refrigeration systems can be complex and potentially dangerous to handle without proper knowledge and equipment.
Contact a professional technician: The best course of action is to contact a qualified appliance repair technician to diagnose and fix the issue with your refrigerator. They can assess the problem, provide a solution, and ensure the appliance is safe to use again.
In the meantime, refrain from storing perishable food items in the refrigerator until it's been repaired and confirmed to be working correctly. If you're uncertain about the safety of any food items, it's safer to dispose of them rather than risking foodborne illnesses.
