How to Fix / Troubleshooting

Safety warning: If you smell burning plastic or see smoke, unplug the unit immediately and do not continue to operate it.

Steps to investigate:

  • New unit consideration: A mild plastic smell can be normal for a brand-new unit during initial operation and should dissipate within a few days.
  • Inspect rear components: With the unit unplugged, remove the rear panel and look for discolored, melted, or charred wiring or components.
  • Check compressor start device: Remove the compressor terminal cover and inspect the start relay and overload for burn marks or melted plastic. Replace if damaged.
  • Examine control board: Inspect the main control PCB for burnt areas or swollen components. Replace the board if damaged.

Action: If any component shows signs of overheating, replace it with a Haier-compatible part or contact a professional technician. Do not operate the cooler until the fault is corrected.
