Display shows E15 and the refrigerator may shut down or trip the household breaker intermittently.

Critical safety warning: If the refrigerator is tripping the breaker or showing signs of electrical burning, disconnect it immediately and do not attempt to power it on repeatedly. Risk of fire or electric shock.

Basic checks (for experienced DIYers only):

• 1. Visual inspection: With power disconnected, remove the rear service panel and inspect wiring around the compressor, defrost heater, and fans for melted insulation or burn marks.
• 2. Isolate loads: If you have electrical experience, you can disconnect suspected loads (e.g., defrost heater connector) and see if the unit powers without tripping (under supervision and with proper precautions). This helps identify the shorted component.
• 3. Test components: Use a multimeter to check resistance of the compressor windings, defrost heater, and fan motors to chassis ground. Any reading near 0 Ω to ground indicates a short.
• 4. Replace faulty parts: Replace any component found shorted to ground with the correct IceKing part. Ensure wiring is routed correctly and secured.

Strong recommendation: Due to the risk involved, E15-type faults are best handled by a qualified appliance electrician or refrigeration engineer.
