Possible Causes
Loose or damaged harness between UI and main control, Failed user interface board, Failed main control board
How to Fix / Troubleshooting
Safety first: Disconnect power before accessing control components.
- Reseat connectors: Remove the control panel and locate the harness between the display/touch panel and the main control board. Unplug and firmly reconnect all multi-pin connectors.
- Inspect for damage: Look for burnt pins, corrosion, or broken wires. Replace any damaged harnesses.
- Determine faulty board: If connections are good and F20 persists, the UI or main control is likely defective. On many GE models, replacing the main control board resolves communication errors; if not, replace the UI board as well.
