Test Function Test mode is perfomed by pushing a keypad and testing for an output
response. When the keypad is released, the output is terminated and
the display will return to the "-" display. The following is a list of key
actions and responses.
NOTE:
1. Each time a key is pressed a tone will sound.
2. If there is a red dot on the IC-chip and the display board when you touch the oven light key,
the oven light will come on and a beep will occur. The beep is to let you know that there is
a good circuit, in case the light is blown. Also, when you press the fan speed key on a dual
speed downdraft, it will beep each time you touch the key. The first beep will be the high
setting, the second beep will be the low setting, and the third beep will be off.
