How to Fix / Troubleshooting
Safety first: Do not work on live wiring. Unplug the freezer before inspecting internal components.
- 1. Check household power: Verify the outlet has power using a lamp or tester. Reset any tripped breakers.
- 2. Inspect power cord: Look for cuts, burns, or kinks. If damaged, replace the power cord with the correct Electrolux part.
- 3. Test outlet and plug fit: Ensure the plug fits snugly and there is no arcing or discoloration at the outlet.
- 4. Access control board: Remove the control housing and check for an internal fuse or thermal cutoff on the board or harness. Test and replace if open.
- 5. Replace main control board: If power is present at the board input but no LEDs or outputs are active, the board's power supply is likely failed. Replace the main control board.
