Safety first: Disconnect power if removing the control panel.

• Check for control lock: Refer to the user manual for the key combination to unlock the controls (often holding a specific button for several seconds).
• Dry the panel: Wipe the control area with a dry cloth to remove moisture or condensation.
• Power reset: Unplug the unit for 5 minutes, then reconnect and test the buttons.
• Inspect keypad: If certain buttons remain unresponsive, remove the front panel and check the ribbon cable and contacts. Clean and reseat.
• Replace UI board: If multiple keys fail and wiring is intact, replace the user interface PCB.
