How to Fix / Troubleshooting

Safety first: Turn off power at the breaker before removing the control panel.

Clean the panel: Wipe the glass or plastic touch surface with a slightly damp cloth, then dry thoroughly. Do not spray cleaner directly onto the panel.
Check for stuck keys: Gently press each key to feel for mechanical sticking. If a key feels different or does not click, the membrane may be damaged.
Inspect ribbon cable: Remove the back cover and locate the ribbon cable from the touchpad to the control board. Reseat it and check for cracks or corrosion.
Dry out moisture: If F7 appeared after a boil-over or heavy steam, leave power disconnected for several hours to allow moisture to evaporate.
Replace touchpad/UI: If F7 persists, replace the touch control panel or user interface board as specified for your Haier model.

Do not pry aggressively on the glass panel; it can crack and require full replacement.

Haier range beeps and shows F7, keys may appear stuck or random inputs occur
