Power supply Board
The EOC is powered by separate power supply board that is mounted on the rear of the range chassis
to the right of the EOC as seen in photo B.

Incoming voltage to the boards should be approximately 120
VAC at P1. Output voltage should be approximately 8 VDC at
P2.
Always test the incoming and outgoing voltage at the power
supply boards when troubleshooting EOC or ESEC control
failures.

EOC Troubleshooting and Testing
The Electronic Oven Control system found in the Electrolux freestanding duel fuel ranges uses a
separate oven relay board to power the individual components such as the bake and broil element,
lock motor, 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 and Power supply board 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 circuit board.
