Electronic Oven Control

Overview

The Electronic Oven Control system consists of the logic board, power supply board, relay board, oven
controls, oven sensor, and door lock assembly.

Caution:

Certain components are electrically HOT when voltage is connected to range.

Bake, broil, and convection units can be on at the same time.

•

Bake, broil, and convection units can operate independently or simultaneously during preheat. There are

•

ve elements in each oven that can operate in any combination. There can be several minutes of off time

between bake and broil unit operation after preheat.
