Possible Causes

How to Fix / Troubleshooting

Safety first: High-voltage components are involved; limit DIY to basic checks.

Step 1 – Verify power supply:

  • Ensure the refrigerator is plugged directly into a wall outlet (no extension cords).
  • Check that the outlet provides stable voltage (ideally 110–120V AC in North America).

Step 2 – Power cycle:

  • Unplug the refrigerator for 10–15 minutes.
  • Plug back in and monitor for 85C.

Step 3 – Check for compressor operation:

  • Listen at the back for compressor startup.
  • If the compressor does not start or repeatedly tries and stops, the compressor or inverter may be failing.

Step 4 – Call a technician:

  • 85C usually indicates a problem with the Inverter Compressor or Inverter PCB, which require specialized tools and sealed system certification to replace.
