Samsung Refrigerator: burning smell

Professional Repair Guide

What is this symptom?

If your Samsung refrigerator emits a burning smell, particularly near the compressor, it's crucial to address it immediately. This odor is often due to a faulty compressor start relay or an overheated power cord, indicating potential electrical issues that could lead to further damage or safety hazards. Take action quickly to ensure your appliance operates safely and efficiently.

Urgency: High

Important Tips for Samsung Models

  • Common reports specifically indicate compressor start device failure as a frequent cause of burning odor and compressor start issues
  • New refrigerators may emit a temporary burning/plastic smell on first use due to adhesives heating, which should dissipate
