4-1 Error Code Numbering Rule
1. ERROR CODE NUMBERING RULE is applied to a microwave oven and an oven .(CMO, OTR, Grill, Convection,
Commercial etc .)
. All sensors and devices have their own number . ex) Gas Sensor = 1, Temp . Sensor = 2, . . .
3. Of each device, No .1 and No .2 refer to “Open Error” (not sensed) and “Short Error”, respectively .
4. This numbering rule has been applied to models to have been developed since January, 1, 2005 . (But, GE or
Customize model are excluded .)
