IMPORTANT SAFETY NOTICE: This information is intended for use by
individuals pos sess ing adequate backgrounds of electrical, elec tron ic and
mechanical experience. Any at tempt to repair a major ap pli ance may result
in personal injury and property damage. Neither the manufacturer nor the
seller can be responsible for the in ter pre ta tion of this information or as-
sume any liability in connection with its use.
DISCONNECT POWER BEFORE SERVICING
IMPORTANT: RECONNECT ALL GROUNDING DEVICES. All parts of this appliance
capable of con duct ing electrical current are grounded. If ground ing wires,
screws, straps, clips, nuts or washers used to com plete a path to ground are
removed for service, they must be returned to their original position and
properly fastened.
GROUNDING SPECIFICATIONS
CAUTION
ALUMINIUM WIRE: – This oven power supply cable
is rec og nized for copper wire only, NOT ALUMINIUM WIRE. Refer to In stal la tion
Instructions for additional details.
T09 CONTROL
The Electronic Range
Control system consists of
the control, key panel, oven
sensor and door plunger
assembly.
Key Panel Test:
Depress each pad on the Key panel followed by the pad. If the Key panel
functions properly, the following should occur:
• Bake, Broil, Clean, Timer, Clock, Stop Time and Cook Time Modes – Audible
tone plus display showing mode of operation selected.
• Clear/Off – Audible tone and display shows time of day.
• Increase/Decrease pads – No audible tone. Can only be used after another
function has been selected.

THERMAL CUTOUT SWITCH (ALL)
SWO & DWO (UPPER & LOWER)
A one-shot thermal fuse is mounted to the rear of the
oven. The switch will open the L2 leg of the power to
the heating elements in the event of an over-temper-
ature condition. The switch will open when the panel
it is mounted to reaches approximately 351°F and will
not reset. The oven will not heat after the switch opens
and the switch will need to be replaced.
THERMAL SWITCH
The thermal switch is located on the rear of the oven above the bake element ter-
minals. The switch will open the neutral leg of the power to the electronic control
in the event of a fan failure. The switch will open when the panel it is mounted to
reaches approximately 216°F and will re-close when the temperature cools below
162°F. If the thermal switch opens during any cooking mode, the control display
will go blank.
MOTORIZED DOOR PLUNGER
The switch on the left is used to detect door status(open or closed). The switch
on the right is for the oven light.

OVEN CALIBRATION
To change:
Testing has shown that this oven has the best cooking performance at a control
setting of 350°F when the AVERAGE center oven temperature is between 335°F
and 395°F. Customers may change the average center oven temperature by +/-
35°F to satisfy their own cooking needs. This affects only BAKE.
SELF-CLEAN and BROIL are not affected.
• Press and hold BAKE and BROIL pads until "SF" appears in the display.
• Press BAKE pad to enter oven calibration mode. "00" or a number between
+ and - 35°F will be displayed. To swap between + and -, press BAKE again.
• Press TEMP increase or decrease pads to change average oven temperature.
• Press START to return to Time of Day.

1. Disconnect power to unit (flip breaker).(LOTO)
2. Remove unit from cabinet.
3. Remove rear wire cover.
4. Remove wires from terminals.
5. Remove screw located between terminals
6. At the front of the unit, remove the door.
7. Remove the trim panel located below the cavity.
8. Remove insulation panels.
9. Remove 2 screws that secure the hidden bake compartment cover in place.
10. With pliers grasp tabs on each side of screw locations and pull forward. This
cover is attached to the element, so the element will be pulled forward with
the cover. Element will have resistance to the pull as it pulls through the
guides. The second row of the element may catch on the opening lip, this
may need to be lifted with a screwdriver to clear the lip.
11. Replacement is in reverse order of removal.
12. Reconnect power. Test operation.
