Freezer shows F4 and may not cool, with compressor not running

Safety: Unplug the appliance. Compressor and surrounding parts may be hot.

Steps:

• 1. Improve ventilation: Ensure the freezer has adequate clearance from walls and that vents are not blocked. Clean dust from the rear grille and condenser.
• 2. Allow cooling: Let the unit sit unplugged for at least 30–60 minutes to allow the compressor to cool and the overload to reset.
• 3. Inspect overload device: Access the compressor terminal cover and check the overload protector for burn marks or deformation. Replace if damaged.
• 4. Listen on restart: After reassembly, plug in and listen. If the compressor hums briefly then clicks off repeatedly, the compressor may be failing and require professional replacement.

Persistent F4 after overload and ventilation checks indicates a likely compressor or control fault; contact a refrigeration technician.
