M1 (AGS1740BD*, MGS5752BD*) Oven Control Testing Procedures
Control Component Test Procedure Results
M1 Controlled Oven temperature
adjustment Press
BAKE
pad.
Enter 550 on the digit-pad.
Immediately press and hold BAKE pad for 3
seconds.
Oven can be adjusted from -35 to +35 degrees
in 5-degree increments by pressing
(Up Arrow)
or (Down Arrow) pads. To avoid over adjusting
the oven, move temperature 5 degrees each
time. Wait 4 seconds for the data entry timer to
expire to accept the change. Temperature
adjustment will be retained even through a
power failure
.
Increasing or decreasing oven
temperature does not affect self-
cleaning temperature.
M1 Controlled Temperature display Press and hold CANCEL and BAKE pads for 5
seconds. Press
(Up Arrow)
or
(Down Arrow)
pads to change.
This mode enables the user to
indicate °F or °C on the display.
M1 Controlled Clock Display Press and hold CANCEL and CLOCK pads for
5 seconds.
Allows clock to be toggled On or
OFF.
M1 Controlled 24 Hour Clock Press and hold CANCEL and DELAY pads for 5
seconds. Press (Up Arrow) or (Down Arrow)
pads to change.
Allows the time on the clock to be
toggled from 12 hour or 24 hour
display.
M1 Controlled Factory Default Press and hold
CANCEL
and
KEEP WARM
pads for 5 seconds.
Allows the clock to be reset to factory
settings.
