NOTE: (*) Ovens are shipped from the factory with this motor and the oven control is configured accordingly.
The values correspond to the current limits only and are not the actual current draw of the motor.

DIAGNOSTIC TEST MODE - PROGRAMABLE CONTROL
The test mode can be entered only when the oven is OFF. The five tests are run in sequence (1 - 5) and are indicated by the position of the illuminated LED in the bar graph of the combi mode key.
The test are performed in a fixed sequence of:
1.ROM (automatically)
2.RAM (automatically)
3.Displays and LED’s
4.Relays (relay on for max. of 2 seconds)
5.Keypad
To Perform:
1.To enter the test mode press the TEMP, TEMP UP and TEMP DOWN keys simultaneously for 3 seconds. The word “test” will be displayed in the temperature display.
2.If a ROM or RAM error is detected, a error code (01 = ROM and 02 = RAM) will be displayed on the temperature display and will repeat until a key is pushed to exit this test. If no errors are detected, the control advances to the next test and runs it automatically.
