26 DIAGNOSING AN ISSUE
Diagnosing Door Switch Operation
From Test Mode screen 1, view status indicator D
as you monitor/adjust the door, hinges, or switch.
Testing the Blower Motor
1. From Test Mode screen 1 (Figure 27), press the
top-left soft key (BLOWER).
2. Continue pressing to raise blower speed in 10%
increments.
Viewing/Clearing the Fault Log
1. From Test Mode screen 1 (Figure 27), press
the middle-left soft key (FAULTS).
2. To zero the fault log, press the Enter.
Adjusting the Temperature Offset
The center of the cook cavity is not usually as hot
as the where the thermocouple takes readings. If
desired, the “temperature offset” feature allows the
displayed temperature to be adjusted for this dif-
ference.
The value entered for temperature offset will
deduct from the oven’s temperature reading. For
example, if the oven temperature = 500ºF, an off-
set of 20º will cause the oven to display 480ºF.
For the most accurate results, measure the tem-
perature in the center of the cook cavity after the
oven has completed warmup and been idle for at
least 15 minutes.
To adjust the temperature offset:
1. From Test Mode screen 1 (Figure 27), press the
bottom-left soft key (OFFSET).
2. Continue pressing to adjust in 5°F increments.
3. Press Enter to confirm.
NOTE: Adjustments can be made only in
Fahrenheit (5ºF equals approximately 2.8ºC).
NOTE: After 20°F, the offset will roll back to 0°F.
Checking Heaters A and B
NOTE: The motor must be running to test the
heaters. If the blower speed is 0%, it will automati-
cally increase to 10% at the initiation of this test.
To turn on heaters A and B (Figure 27):
1. From Test Mode screen 1, press the top-right
soft key (HEATER A) to turn heater A on/off.
2. Press the middle-right soft key (HEATER B) to
turn heater B on/off.
Testing the Rack Oscillator Motor
NOTE: The Oven Rack will not oscillate if it is
not properly set on the support pins.
To test the rack oscillator motor:
1. From Test Mode screen 1 (Figure 27), press the
bottom-right soft key (RACK OSC) to turn the
rack motor on/off.
Enabling/Disabling Diagnostic Mode
When Diagnostic Mode is enabled, the following
features will be available during a cook cycle:
£
Event settings (see page 19 for more details).
£
Status indicators (see page 25 for more details).
To enable/disable Diagnostic Mode:
1. From Test Mode screen 1, press the Down
Arrow key to view screen 2 (Figure 28).
2. Press the top-left soft key (DIAG) to turn
Diagnostic Mode on or off.
Viewing Cook Counter/Time
The oven logs how many cook cycles have com-
pleted, as well as the cumulative cook time (shown
in minutes and seconds). To view cook counter/
time:
1. From Test Mode screen 2 (Figure 28), press the
middle-left soft key (COOKS) to view the total
number of cook cycles completed.
2. To view the cumulative cook time, press the
middle-left soft key (COOKS) again.
NOTE: To permanently erase the cook counter/
cumulative cook time, press the Enter key.
