Display shows 84E; compressor may not start or runs briefly then stops; freezer warms quickly.

Danger: Work around the compressor and high-voltage circuits should only be done with power disconnected. If you are not experienced with electrical diagnostics, contact a professional.

• Power reset: Unplug the unit for 10–15 minutes, then restore power. If 84E reappears, continue.
• Check ventilation: Ensure the condenser area is clean and the unit has adequate clearance around it. Overheating can trigger compressor errors.
• Listen to compressor: When power is restored, listen for the compressor attempting to start. Clicking or humming followed by a stop suggests a mechanical or electrical compressor issue.
• Inspect wiring and inverter board: With power off, remove the rear access panel and inspect the compressor terminals, inverter PCB, and wiring for burns or loose connections.
• Professional diagnosis: Testing compressor windings and inverter output requires a multimeter and often specialized tools. If the compressor is locked or windings are shorted, the compressor and possibly the sealed system must be replaced by a certified technician.
