Possible Causes
Communication failure between UI board and main PCB, Loose harness connectors, Electrical noise or surge damage, Faulty control board microcontroller
How to Fix / Troubleshooting
Safety first: Turn off power before accessing internal boards.
- Reseat connectors: Remove the control panel and top cover. Locate the multi-pin connectors between the user interface board and main control board. Disconnect and reconnect them several times to clean contacts.
- Inspect harness: Check the communication harness for pinched or damaged wires. Replace the harness if any conductor is broken.
- Power quality: Ensure the oven is on a stable supply and not sharing a circuit with heavy inductive loads that cause surges. Consider using a surge protector if permitted.
- Board replacement: If E19 persists, either the UI board or main PCB may be defective. Replace one at a time, starting with the UI board, then the main PCB if needed.
