Safety: Unplug before opening the control panel.

Dry and clean: If a spill occurred, carefully open the panel and dry the area. Clean sticky residue with isopropyl alcohol on a cloth.
Check ribbon cable: Ensure the flat cable between the keypad and main PCB is fully inserted and not damaged.
Test buttons: If only certain buttons fail consistently, the keypad membrane is likely worn.
Replace control panel: Install a new Midea control panel or UI board assembly as specified for your model.
