Freezer display shows error, interior light not working, no response to buttons

Safety first: Disconnect power before opening the control panel. Avoid static discharge to electronic components.

Steps:

• Check child lock: Some Hotpoint models have a control lock feature. Hold the lock/unlock button (often 3–5 seconds) to ensure the panel is not simply locked.
• Power reset: Unplug the freezer for 5–10 minutes to reset the electronics, then plug back in and see if the display recovers.
• Inspect the control housing: Remove the screws securing the top or front control panel. Gently pull it forward to access the display board and wiring.
• Check connections: Ensure the ribbon cable and harness connectors between the UI board and main board are fully seated and not damaged.
• Look for corrosion: Signs of moisture or corrosion on the display PCB indicate it should be replaced.
• Replace UI board: If the main board is supplying power but the display remains dead or erratic, install a new Hotpoint-compatible user interface/display board. Transfer any button overlays as needed.
• Reassemble and test: Refit the panel, restore power, and verify that buttons respond and the display shows correct temperatures.
