Freezer displays EA and may not maintain set temperature; compressor cycles irregularly.

High-voltage safety: Unplug the freezer before touching compressor wiring. Compressor diagnosis often requires a professional; proceed only if you are experienced.

Steps:

• 1. Check ventilation: Ensure the condenser at the back or bottom is not blocked by dust or objects. Clean the condenser coils with a soft brush and vacuum.
• 2. Listen to compressor: Restore power briefly and listen. Repeated clicking without sustained running suggests overload tripping.
• 3. Inspect start components (non-inverter): Unplug again. Remove the start relay/overload protector from the compressor terminals. Shake the relay gently; if it rattles or smells burnt, replace it with a Toshiba-specified start device.
• 4. Measure compressor winding resistance: Check resistance between terminals and to ground. Very low resistance or a short to ground indicates a failed compressor.
• 5. Check condenser fan (if equipped): Ensure the condenser fan motor runs freely and is not obstructed, as poor airflow can cause overcurrent.
• 6. PCB current sensing: If mechanical parts are good but EA persists, the main PCB's current sensor may be faulty and require replacement.

Note: Compressor replacement and refrigerant work must be done by a licensed refrigeration technician.
