Upper Oven (DRT) Thermostat
The front of the thermostat contains a switch; this switch is an input to the ERC control.
This input provides (on or off) information to the ERC so the ERC can control the Upper
Oven Lockout Control. This also provides the ERC the ability to control the hydraulic
thermostat Self Clean timing of 5 hours. This switch closes when the thermostat is off
and opens when the thermostat is in any on position. If the switch does not open the
ERC will not allow self clean.

Cooling Fan – Café Models
On Café models – there is a squirrel cage cooling fan in the right rear corner of the
cooktop. To service the fan requires removal of the cooktop. Once the cooktop is
removed, remove the six ¼” Hex head screws that hold the fan housing and lift up to
remove the fan assembly. The fan motor is controlled by the ERC and the oven sensor

FAD – Café Models
On Café models with the cooling fan there is also a FAD (Fan Apparent Device). This
thermostat will disable the ovens in an over temperature issue due to a cooling fan
failure. The FAD is a self resetting thermostat that opens at 265˚F and closes at 225˚F.
If either oven is terminating Self Clean before time out, check Fan and FAD operation.

Upper Oven Lockout Relay
The upper oven uses a lock out relay that will
disable the upper oven from operating when
the lower oven is in self clean. When the lower
oven is placed into clean the relay is activated
by the ERC disabling the upper oven
thermostat control. The ERC also uses this
relay to terminate the upper oven self clean
cycle at a preset 5 hour cycle.

Upper Oven Lockout Relay
The ERC activates the lockout relay from the “OUT WD” terminal when in clean. When
powered the relay opens the cycling contact circuit of the thermostat (NC contact). In
the Upper Oven clean cycle the ERC powers the thermostat through the MDL terminal.

Gas Lockout Valve
These models also utilize a gas lock out valve which turns the gas off to the cooktop.
This feature can be activated by the consumer through the ERC control and it is
automatically activated during self clean.

11/28/2011
50 /
Gas Lockout Valve
The gas lockout function is activated by the ERC when selected by the consumer or
when a Self Clean cycle is activated. The Lockout valve will NOT operate if a surface
burner is in the on position. Each burner switch must be in the open (OFF) position state
to complete the gas lockout function. The ERC AUX terminal sends power down to the
surface burner switches and when ALL are closed (burners off) the lock out motor runs.
Copyright General Electric 2011
11/28/2011
51 /
Gas Lockout Valve
The gas lockout valve incorporates two positioning switches to allow the ERC to know
the position of the lockout valve. Yellow to Orange closes when the valve is open and
allowing gas flow to the cooktop. This switch opens and Yellow to Silver close when the
valve is closed.
ERC
Loss of the Yellow to Orange contact will cause the lockout motor to run continuously
and LOC will flash in the ERC display. Loss of the Yellow to Silver will cause the lockout
motor to run continuously when Lock Out or Clean is selected; LOC will flash in the
display. LOC will display steady when the cooktop is locked out.

Cavity TCO‟s – All Models
Both upper and lower oven cavity TCO‟s (Thermal Cut Outs) are wired in series between
the latching motors and the ERC. If either TCO opens
during a clean cycle, the cycle will terminate and the
ERC will return to TOD (Time Of Day). If either TCO is
open at the start of a clean cycle; the ERC will beep
until the cancel button is pressed, no “F” code will be
displayed. The error code will be logged into the ERC
Memory and can be retrieved in diagnostic mode.
Both TCO‟s are rated 176˚ F open, 158˚ F close.

Self Clean Sequence of Operation
When the lower oven is placed into clean mode,
1. The gas lockout valve rotates to shut off the cooktop gas, returns signal to ERC.
2. The lower oven latch locks the door , returns signal to ERC.
3. The upper oven latch locks the door , returns signal to ERC.
4. The upper oven lockout relay is activated , returns signal to ERC.
5. The cooling fan is turned on. (Café models)
Clean time can be set from 3 to 5 hours, default is 4 hours.
When the cycle is complete,
1. The lower oven unlocks , returns signal to ERC.
2. The upper oven unlocks , returns signal to ERC.
3. The gas lockout rotates to allow gas flow to the cooktop , returns signal to ERC.
The upper oven follows the same sequence, the cycle time is fixed at 5 hours.
The spark module remains active but the burners will not light during clean.
Note: if any of these sequences fail; the ovens will NOT self clean.

Spark Module Location
The spark module on the Profile & GE models is located in the control panel.
On Café models the module is located on the back of the unit adjacent to the gas
lockout valve. When any surface burner is lit all igniters spark.

Bake & Broil Burners
The bake and broil burner orifices no
longer allow for adjustment.
When the unit is converted for LP
gas, new orifice hoods need to be
installed.
Without an adjustment, the hood
must be replaced if there are
combustion issues. But, this change
eliminates the possibility of damage
to the orifice hood needle valve by
the installer.

Bake & Broil Burners
The bake burners utilize a non-caged glow bar igniter. Be sure to use the proper
replacement, these are NEW igniter parts, the wiring harness‟ are longer. The
igniter is secured to the burner bracket with two ¼” hex screws. To access the
harness plugs requires removal of the oven back panel. Glow bar amperage is
approximately 4 amps. The upper oven glow bar is caged since it is open to the
oven cavity.
