5. Principy fungování

The LG EBR74164805 Relay Control Board acts as an intermediary between the main oven control board and the heating elements (bake and broil). It receives electrical signals from the main control board, which dictate when and how much power should be supplied to the oven's heating elements. The relays on this board then open or close to regulate the flow of electricity, ensuring the oven reaches and maintains the desired temperature for cooking.

6. Údržba

The relay control board is a sealed electronic component and generally does not require routine maintenance. However, periodic inspection during other appliance servicing can help identify potential issues early. Ensure the area around the board is free from dust, debris, and moisture. If any signs of damage or overheating are observed, the board should be inspected by a qualified technician.

7. Řešení problémů

If your LG oven is experiencing heating issues, the relay control board may be a contributing factor. Below are common symptoms and potential solutions:

• Trouba se nehřeje: If the oven does not heat at all, or heats inconsistently, the relays on the board might be faulty.
• Oven Not Reaching Desired Temperature: This can indicate a relay failing to close properly, preventing full power to the heating elements.
• Přehřátí trouby: A relay stuck in the closed position could cause continuous heating.
• Kódy chyb: Specific error codes on your oven's display may point to a control board issue. Consult your oven's main user manual for error code definitions.

Before replacing the board:

• Verify that the heating elements themselves are not faulty.
• Check all wire connections to ensure they are secure and free from corrosion or damage.
• Ensure the oven's temperature sensor (thermistor) is functioning correctly.

If these checks do not resolve the issue, replacement of the relay control board may be necessary.
