EOC Troubleshooting and Testing
The Electronic Oven Control system found in the Electrolux freestanding electric ranges uses a
separate oven relay board to power the individual components such as the bake and broil elements,
lock motor, warmer drawer or lower oven element, etc. This is different from some other styles of
electronic oven controls where the EOC and control relays are integrated in to a single component.
The servicer must follow the troubleshooting and diagnostic information found in this manual and in
the product tech sheet to accurately diagnose any failures and avoid unnecessary parts replacement.
Photo A shows the locations of the EOC Board, Oven Relay Board, ESEC 30 UIB and Power supply
boards as seen from the rear of the range with the rear panel removed. The ribbon connectors to the
TST panel can be seen at the bottom of the EOC board.
