Demo Mode

The Sales Demo mode will allow dealers to
demonstrate all oven functionality with one
exception: No power is ever applied to any of the
halogen lamps, heaters, mag HVT or inrush relays
while the control is in sales mode.
The sales mode will be initiated by holding the
"POWER / TEMP" and "START" pads down at the
same time for a full 3 seconds. This mode can only
be entered during the initial "SELECT TIME" display
that occurs when the unit powers up after a long
(>60 seconds) power outage. When sales mode
is initiated, a 2 short-beep signal is sounded and
all oven functions will operate with the following
exceptions;
1. No power shall ever be applied to any the
heaters, Halogen lamps, magnetron HVT or
Inrush control relays. The control relays for
any of these loads shall not be switched during
sales mode.
2. The DEMO icon will be lit whenever the unit is in
sales mode regardless of settings or the feature
being selected.
The sales mode is cleared by holding the "POWER
/ TEMP" and "START" pads down at same time for a
full 3 seconds. The sales mode can only be cleared
during the same initial "SELECT TIME" display that
occurs when the unit powers up after a long (>60
seconds) power outage. After 5 seconds elapse, all
functions of the oven will return to normal operation.
When power-up occurs, software will check the
special sales demo identifi er code. If the code is
set, then the oven will stay in the sales demo mode.
This will prevent the unit from powering back up to
a normal mode if power to the salesroom had gone
off .

Standard Test Load

The standard test load is one liter (1000 ml) water
with starting temperature of 59°F ~ 75°F in a 1000
ml beaker. (DO NOT USE ANY OTHER LOAD OR DISH
AS RESULTS WILL VARY FROM STANDARD.)
PERFORMANCE TEST FOR MICROWAVE
1. Use Clear Glass Tray and the beaker.
(Part # WB64x0073)
2. Record initial water temperature.
3. Run at high power for 2:03.
4. Record end water temperature. The minimum
difference between the initial and ending
temperature should be: 32°F @ 120V.

Fault Codes

The smart board monitors various operations and
can detect certain failure modes. In the event of
specifi c failures, cooking will be terminated, a four
beep signal will be heard, and a fault code will be
displayed.
Pressing the CLEAR pad will remove the fault code
display, unless the failure is a shorted keypanel
switch. Detection of a failed sensor will have no
effect on features that do not use that sensor.
F4 (open or shorted humidity sensor) and F6 (high
cavity temperature during microwave cooking)
codes apply only to microwave cooking. The
chart below indicates failure modes which can be
detected and displayed.
