Bake Element; Operational Notes; Sales Mode - GE PT920 Technical Service Manual

Sales Mode

The oven control can be operated in SALES MODE.
When the unit is connected to 120 VAC from L1–N,
the control will function normally. The 240 VAC
relays will not function.

Operational Notes

Certain modes, when selected, will automatically
enter into a preheat. The PREHEAT light will turn
on and 100°F will appear in the display. (The
temperature display will start to change once the
oven temperature reaches 100°F.)
For convection ovens, the convection fan will run
during the Single-Rack preheat cycle and remain
on until the oven has reached the set temperature.
The bake element is on for 20 seconds, then the
broil element is on for 70 seconds until preheat is
completed. After preheat, the bake element or the
broil element is cycled to maintain temperature.
Multi-Rack preheat cycle uses only the bake
element with the convection fan.
For non-convection ovens, the bake element is on
for 60 seconds, then the broil element is on for 30
seconds until preheat is completed. After preheat,
the bake element or the broil element is cycled to
maintain temperature.
The control will beep when the oven is preheated―
this may take approximately 10 minutes. The
PREHEAT light will turn off and the display will show
the set temperature.

Probe Usage
*Preheat for Convection Roast uses only the broil
element with the convection fan. The convection
will NOT reverse directions during Convection Roast
preheat.
• The convection fan will cycle on and off to
change direction while cooking to best distribute
hot air in the oven. The convection fan shuts off
when the oven door is opened.
• A cooling fan will turn on to cool internal parts.
This is normal, and the fan may continue to run
even after the oven is turned off.
• Broil will not work if the temperature probe is
plugged in.
• When using the probe, you can use the timer,
but you cannot use timed oven operations.
• On the double wall oven, the oven control will
automatically set the oven that has the probe
plugged into it.
• In Convection Bake, the bake element and the
fan operate whenever the oven is preheating.
• On the double wall oven, you can use timed
baking in both ovens at the same time.
• The Clean cycle can be set for a minimum of 3
hours and a maximum of 5 hours. The default
setting is 5 hours. The 5-hour set time consists
of 4 hours and 20 minutes of cleaning and 40
minutes of cool down. The door will unlock at an
approximate temperature of 450°F.
• On the double wall oven, you can set a clean
cycle in both ovens at the same time. The last
oven set will automatically delay its start until
the fi rst oven's clean cycle cools to 400°F. On
the double wall oven, you can bake or broil in
one oven and self-clean in the other at the same
time.
