Possible Causes
Low or unstable household voltage, Internal power supply failure on main PCB, Loose power cord connection, Damaged surge components on board
How to Fix / Troubleshooting
Safety first: Unplug the freezer before inspecting the power cord or internal components.
Steps:
- Check outlet: Plug a known-good appliance or tester into the same outlet to confirm proper voltage. Avoid using extension cords or power strips.
- Inspect power cord: Look for cuts, burns, or kinks in the Midea freezer's power cord. Replace if damaged.
- Surge protection: If F5 appears after a storm or power surge, the internal power supply on the main board may be damaged.
- Board inspection: Access the main PCB and look for burnt components, bulging capacitors, or cracked solder joints near the power input.
- Replace board if needed: If visible damage is present or F5 persists despite stable supply, replace the main control board.
Note: If your home's voltage is unstable, consult an electrician; repeated low-voltage operation can damage the freezer.
