E16 error; freezer may trip the household breaker or blow fuses when starting.

Safety first: If the breaker trips repeatedly, leave the freezer unplugged until the fault is found. Do not replace breakers with higher ratings.

Step-by-step checks:

• 1. Inspect power cord: Check the entire length of the Hansa power cord for cuts, crushed sections, or burn marks. Replace if damaged.
• 2. Check defrost heater: Disconnect the defrost heater leads and test for continuity to ground (compressor shell or cabinet). Any continuity indicates a ground fault; replace the heater.
• 3. Test compressor to ground: With wires removed from compressor terminals, measure resistance from each terminal to the compressor shell. Any reading other than infinite indicates a shorted compressor, requiring professional replacement.
• 4. Inspect control board: Look for carbon tracks, burnt components, or moisture on the PCB. Dry thoroughly and replace the board if damaged.
