Introduction - GE Advantium PSA1200R Technical Service Manual

The Advantium 120 V ATC is an "Above The Cooktop" oven that has the functionality of a microwave,
convection, and speedcook oven. Four heat sources are available for cooking. A 500-watt halogen light and
700-watt ceramic heater are located at the top of the unit. A convection system, located behind the right-
side of the oven cavity, provides a 1550-watt heat source and fan to circulate cavity air. A 375-watt ceramic
heater provides additional heat from the bottom of the oven. The Advantium can also be used as a 900-watt
microwave oven.
The oven operates in one of 8 consumer modes and 2 special modes:
• Idle - No cycles have been selected; unit is plugged in and idle.
• Speedcook - Used for faster cooking. Uses the upper and lower heaters along with the microwave. The
upper and lower heaters share time with the microwave.
• Microwave - Functions as a standard microwave; cooks with microwave energy only.
• Convection - Uses only the convection element and convection fan.
• Broil - Uses the upper heaters only.
• Toast - Operates similar to Broil.
• Warm - Used to keep items warm after they have been cooked.
• Proof - Provides correct temperature for proofi ng dough.
• Service Test Mode - Used to operate loads for testing (not used by consumer).
• Demo Mode - Used by dealer to demonstrate operation without operating heat loads.

Operating Modes
information pertaining to load cycling.
Cooking modes are started by pressing a key on the key panel. When a selection has been made, a menu
appears on the display. The selector knob is then used to navigate. Rotating the knob allows scrolling menu
items and highlights each item. When the knob is pressed in, the highlighted item is selected. Press the start
key and the cycle starts.
When the cycle starts, the Smart Board sends 5 VDC to the appropriate relays on the Relay Board. The relay
then switches neutral to the load. Loads are operated according software algorithms contained in the Smart
Board.
To troubleshoot the oven:
1 Determine in which mode of operation the failure is occurring.
2. Check the
Load Algorithm Chart
3. Determine which part is not functioning correctly.
4. Look up failing part in the table of contents.
5. Go to the appropriate page and fi nd the troubleshooting section for that part.
6. Follow troubleshooting instructions.
