How to Fix / Troubleshooting
Safety: Unplug the freezer before working on the control panel.
Steps:
- 1. Inspect panel surface: Look for signs of spills, condensation, or physical damage around the buttons.
- 2. Clean panel: Wipe the surface with a slightly damp cloth and then dry thoroughly. Do not allow liquid to enter gaps.
- 3. Remove panel: Access the display PCB and check for corrosion or residue. Clean gently with isopropyl alcohol if needed.
- 4. Button test: With power restored, press each button individually. If one button causes continuous beeping or no response, the keypad circuit is likely damaged.
- 5. Replace display/keypad PCB: Install the correct Panasonic control panel PCB assembly.
