DIAGNOSTIC MODE

16 THE CONTROL SYSTEM

Diagnostic Display (Screen 2)

The DIAG key turns on or off the diagnostic display feature. When this feature is enabled, the oven will display temperature and cook cycle parameters when the oven is cooking or idle.

In addition, the status indicators are displayed on the bottom of the screen. When a status indicator is highlighted/backlit the corresponding system is off or open. For example: W would indicate that the Microwave System is off.

The STATUS INDICATOR section below offers a more detailed description of each indicator.

COOKS (Screen 2)

Press once to display the total number of cook counts for all recipes. Press again to display the total amount of time the oven has been in cook cycles.

ACCUM (Screen 2)

Press once to display the total amount of time the magnetrons have been on. Press again to display the total amount of time the oven has been on.

Electronic Compartment Temperature (Screen 2)

The ºELEC key displays the temperature inside the electronic compartment.

F/C (Screen 2)

Changes how the oven’s temperature units are dis- played. The F/C key alternately selects Fahrenheit or Celsius.

IR SI (Screen 2)

Displays the idle IR set point. This temperature is a factory setting and should never be altered. If an incorrect temperature has been entered, consult the factory before changing this value.

STATUS INDICATORS

See Figures 9 and 10 on page 15.

PPrimary switch – closed or open S Secondary switch – closed or open M Monitor switch – closed or open

t Magnetron thermostats – closed or open h Main convection heater – off or on

i IR element – off or on

A Blower motor controller – enabled or disabled W Microwave current – Less than or greater than 7

Amps*

*Microwave (W) status indicator is not highlighted/backlit when the current is more than 7 Amps.

Status indicators are displayed at the bottom of the display screen when the oven is in TEST MODE, or during normal oven operation if in

(DIAG was turned on). Refer to Figures 9 and 10.

If a status indicator is highlighted/backlit, the item or component is in an un-energized or off state. Conversely, if a status indicator is not highlighted, the component is in an energized or on state.

PROGRAMMING

Edit Mode

The EDIT MODE enables the operator to manually alter recipes and the cook cavity temperature (CCSP).

To access EDIT MODE:

1.Simultaneously press the UP and DOWN keys.

2.When prompted, enter the access code “9” and then press the ENTER key.

NOTE: If this does not provide access, refer to page 19 for enable/disable codes.
