Freezer not cooling at all, no compressor or fan noise, display off

Safety: Before any internal checks, unplug the freezer and ensure the outlet is safe.

Steps:

• 1. Verify outlet: Plug a lamp or tester into the same outlet to confirm power is present.
• 2. Check breaker: Reset any tripped breaker or replace a blown fuse in the home panel.
• 3. Inspect power cord: Examine the Panasonic freezer's power cord for cuts, burns, or crushed sections. Do not use the unit if the cord is damaged; replace it.
• 4. Internal line filter: If comfortable, remove the rear/top panel to locate the line filter module and main PCB. Look for burnt components or a blown internal fuse.
• 5. If internal fuse is blown: This usually indicates another fault (shorted component). Replacement and further diagnosis should be done by a technician.
