Electronic Oven Control - GE Profile PT925 Technical Service Manual

Oven Circuits
All closed switches shown above are closed during the respective cooking cycle. All open switches cycle
during the respective cooking cycle.
Note:
• Relay – This relay is external to the control boards and is mounted on the back cover of the unit. This
relay is connected to the upper plunger switch and opens and closes based on the plunger position.
• Element Relay Cycling – All cavity elements cycle during preheat and once the oven cooking
temperature is reached. However, only the bake, inner broil, and convection elements come on one at a
time (multiple elements are not energized).
• Power Sharing Mode – The outer broil elements are disabled when both ovens are in operation.
• Relay/Board Designations – All relays listed above for each oven correspond to their respective oven
relay boards except for the cooling and convection fans. The cooling fan is located on the upper oven
relay board, and the convection fan is located on the lower oven relay board.
