  • 2. Inspect start device: Remove the compressor terminal cover and check the relay and overload for burn marks or odor. Replace if damaged.
  • 3. Test overload: Check continuity; replace if open at room temperature.
  • 4. Assess compressor: If a new start device does not resolve the issue, the compressor may be seized and requires professional replacement.
