Oven Control Testing Procedures
Illustration 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 to 5 seconds.
Oven can be adjusted from -35 to +35
degrees in 5-degree increments by
pressing
(slew up) or (slew down)
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.
While increasing or decreasing oven
temperature, this does not affect self-
cleaning temperature.
M1 Controlled Temperature display Press and hold
Cancel and Bake
pads for 3 to 5 seconds. Press
(slew up) or (slew down) 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 3 to 5 seconds.
Allows clock to be toggled On or OFF.
M1 Controlled 24 Hour Clock Press and hold
Cancel and Delay
pads for 3 to 5 seconds. Press
(slew up) or (slew down) 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 3 to 5 seconds until
beep sounds.
Allows the clock to be reset to factory
settings.
M1 Controlled Twelve hour off Control will automatically cancel any
cooking operation and remove all relay
drives 12 hours after the last pad
touch.
See Sabbath mode to disable.
M1 Controlled Sabbath Mode Hold
Clock pad for 3 to 5 seconds to
activate Sabbath mode.
Hold
Clock for 3 to 5 seconds to
disable Sabbath mode.
Desired bake function must be
initiated before entering Sabbath
mode.
"SAb" will be displayed and flash for 5
seconds then remain on until timed-out
or cancelled.
The status "SAB" is NOT fault code 5A6.
All pad inputs are disabled except for
CANCEL and CLOCK pads.
This mode disables the normal 12 hour
shutoff to allow operation of the bake
mode for a maximum of 72 hours.
The oven light is not disabled.

M1 Controlled Child lockout Press and hold
Cancel and Cook &
Hold
pads for 3 to 5 seconds until
beep sounds.
To reactivate the control, press and
hold
Cancel and Cook & Hold pads
for 3 to 5 seconds.
This is a safety feature that can be used
to prevent children from accidentally
programming the oven. It disables the
electronic oven control.
Child lockout features must be reset after
a power failure.
M1 Controlled Diagnostic Code
Display
Press and hold
(slew up) pad within
60 seconds of powering up the unit.
Cycle through the codes using the
(slew up) or (slew down) pads.
The last 5 diagnostic codes will be stored
in the non-volatile memory.
See "Description of Error Codes" for
explanation.
"Quick Test" Mode for Electronic Range Control
Follow procedure below to use the quick test mode. Entries must be made within 32 seconds of each other or the
control will exit the quick test mode.
1. Press and hold
Cancel and Broil pads for 3 to 5 seconds.
2. Once the control has entered the "Quick Test" mode, release both pads.
3. Press each of the following pads indicated in the table below.
NOTE: The first time one of the following pads is pressed it will activate the response.
The second time the pad is pressed it will deactivate the response.
NOTE: This mode must be entered within the first 5 minutes after power up.
NOTE: If the temperature sensor is greater than 400° F or if the temperature sensor reaches 400° F while under
test, the Quick Test mode will be disabled.
Display will indicate the following:
Key Operation
[Bake] Bake relay activated, DLB relay activated
[Broil] Broil relay activated, DLB relay activated
[Keep Warm] DLB relay activated
[Cook&Hold] Last Diagnostic Code displayed
[Clean] Beep sounds
[Delay] (M1) EEPROM Version Number displayed
[Timer] Main Code Version Number displayed
[Clock] All Segments On
[More +] Even Segments On
[Less –] Odd Segments On
[Cancel] End Factory Test Mode

Description of Error Codes
Error diagnostic codes can be viewed by entering the Diagnostic Code Display Mode.
Each error code consists of four digits and each digit is described in the following table.
Digit Description
1st Primary System: 1 – Local to the control circuit board
3 – Sensor or meat probe
4 – Control input
9 – Door lock
2nd Measurable: d – Diagnostic: measurable parameter
c – Control related, replace control
3rd Secondary System: Sequential numbering
4th Oven Cavity: 1 – Upper oven (or single cavity oven)
2 – Lower oven
c – Control specific
Diagnostic Code Display Mode may only be started within 60 seconds when powering up the control.

NOTES:
1"Action Taken" applies as long as the condition exists. If the condition goes away, the control recovers.
2If there is a cook function or timer active, the function continues. The user cannot edit the function, and [Cancel] will cancel the cook
mode.
3Flash rate: 0.2 seconds on, 0.1 second off. Pressing any key will clear the display until the fault clears and is re-triggered.
4"Action Taken" applies until there is a POR (Power On Reset ["hard reset"]).
5If the control believes the door is locked, unlock it when the function cancels and the cavity temperature cools.
6Special conditions for latch faults (9dxx):
•A known good unlock position is defined as when the unlock switch reads closed and lock switch reads open.
•A known good lock position is defined as when the unlock switch reads open and lock switch reads closed.
•A faulted switch means the switch input is reading an invalid state, neither open nor closed.
•If at POR, the latch is not at a known good unlock position:
•Affected DLBs (Double Line Breaks) and loads are disabled during detection.
•If the control is in a known good unlock position and the lock switch becomes faulted:
•The control will not fault.
•If a function requiring latch movement is attempted while the lock switch is faulted, the control will sound an error
tone and the function will be disabled.
