WILL CREATE A POTENTIAL HAZARD.
6. Prior to returning the product to service, ensure that:
• All electric connections are correct and secure.
• All electrical leads are properly dressed and secured away from sharp edges, high-temperature components,
and moving parts.
• All non-insulated electrical terminals, connectors, heaters, etc. are adequately spaced away from all metal
parts and panels.
• All safety grounds (both internal and external) are correctly and securely reassembled.
• All panels are properly and securely reassembled.
ES400 ELECTRONIC OVEN CONTROL
The ES400 electronic oven control is similar to the ERCIII control with a few exceptions.
1. This self-cleaning controler offers Bake, Broil, Preheat, Convection Bake and Convection Roasting modes, Timed
and Delayed Baking, and Cleaning functions.
2. Convection operates with an element and a fan dedicated to convection.
3. Slew and dial are replaced by a digit key pad.
4. No external relays.
NOTE: The controler's are not field repairable. Only temperature settings can be changed. See oven calibration.
NOTE: Depending on model, the size and shape of touch pads may vary (for example round instead of elliptical).(Some
models may also have round push buttons instead of touch pads).

CONVECTION MODE
The convection oven uses the addition of a fan and an element to heat and to move the air already in the oven. Moving
the heated air helps to destratify the heat and cause uniform heat distribution. Cooking times can be reduced by as
much as 30%. The air is drawn in through a fan cover and the element located on the rear wall of the oven. It is
then discharged around the outer edges of this cover. The air circulates around the food and then enters the cover again.
As with conventional electric ranges, there is still an oven vent which discharges through the rear of the cooktop.
To set the control in convection mode, follow these steps:
1.Press the CONV. BAKE or CONV. ROAST pad.
2. Enter the desired temperature on the keypad (setpoint).
3. Press the START pad.
The oven will automatically start and the fan will begin to run. To cancel the convection baking/roasting function, press
the CANCEL pad.
NOTE: The fan runs continuously while in the convection mode. The fan will stop if the door is opened while
convection baking/roasting. The bake element will continue to operate if the door is opened.
CONVECTION MODE OVEN TEMPERATURES
Convection Bake/Roast
Because heat is more evenly distributed in convection mode, foods can be cooked in less time.
BAKE
During a bake mode, the oven uses bake element to reach the controler set point. The element uses full power when
it's on. When the set point is reached, the controler adds top heat by cycling the broil element on for 6 to 9 seconds
per minute . The bake element is on for the remaining time of the minute.
PREHEAT
During a preheat mode, the controler preheats the oven with the bake element. When the desired temperature in
the oven is reached, the controler adds top heat by cycling the broil element on for 6 to 9 seconds per minute . The
bake element is on for the remaining time of the minute. Both elements use full power when they are on but they
are never on at the same time.
CLEAN
During a cleaning process, the oven uses bake element .
CLEAN AND TIMED CLEAN
When these modes are called, the door locks right after start button is pushed.
FIRST RISE
It is normal to see a temperature overshoot in the
first rise of all modes when you monitor the temperature. set point

OVEN CALIBRATION
Set the electronic oven control for normal baking at 350°F/177°C. Obtain an average oven temperature after a
minimum of 5 cycles. Press Cancel to end bake mode.
Note: Changing calibration affects all the cooking modes but not the clean mode.
ELECTRONIC OVEN CONTROL
Note: Only three families of fault codes are displayed by this control “F1”, “F3”, and “F9”. Generally speaking “F1” implies
an internal control failure, “F3” an oven probe problem, and “F9” a latch motor problem. In all ocurrences the alarm is
accompanied by a display of the error code.
1. Shorted keypad.
2. Control's internal checksum may
have become corrupted.
3. Control has sensed a potential
runaway oven condition. Control may
have shorted relay, RTD sensor probe
may have gone bad.
1. Open RTD sensor probe/ wiring
problem. Note: EOC may initially
display an "F1", thinking a runaway
condition exists.
2. Shorted RTD sensor probe / wiring
problem. Note: "F3" is displayed
when oven is in active mode or an
attempt to enter an active mode is
made.
3. Abusive operation (safety
thermostat).
4. Safety thermostat opened, or cooling
fan stalled.
1. Door motor failure / jammed. Latch
motor switch failure.
2. Control software failure, or
component failure (relay stuck).
3. Wiring Problem.
Likely Failure Condition/Cause Suggested Corrective Action
Fault Code
1. Press CLEAR or CANCEL pad.
2. Disconnect power, wait 30 seconds and reapply power. If
fault returns upon power-up, replace EOC.
3. Check RTD sensor probe and replace if necessary. If oven
is overheating, disconnect power. If oven continues to
overheat when the power is reapplied, replace EOC.
Severe overheating may require the entire oven to be
replaced, should damage be extensive.
1. Press CLEAR or CANCEL pad.
2. Check wiring in probe circuit for possible open or short
condition. Check RTD resistance at room temperature
(compare to probe resistance chart). If resistance does not
match the chart, replace the RTD sensor probe.
3. Let the oven cool down and restart the function
4. Look for stalled cooling fan, broken safety thermostat
(opens).
1. Press CLEAR key.
2. If CLEAR key does not eliminate problem, turn off power
for 30 seconds, then turn on power.
3. Check wiring of Lock Motor, and Lock Switch A and B, and
Door Switch circuits.
4. Apply power (L1) directly to the Lock Motor, if the motor
does not rotate, replace Lock Motor Assembly.
5. Check Lock Switch A, and B for proper operation (do they
open and close, check with ohmmeter). The Lock Motor
may be powered as in above step to open and close Lock
Switches. If the Lock Switches are defective, replace Motor
Lock Assembly.
6. If all above steps fail to correct situation, replace control.

FAN BLADE
The fan blade is mounted in the rear of the unit and has a "D" shaped mounting hole. Only minimum clearance exists
between the oven back, fan blade, and fan shroud. Be careful not to bend blade when removing or installing.
Access to the fan blade is gained by removing the fan shroud, held in place by three screws, from the inside of the oven.
The fan blade is held in place with a hex nut that has left handed threads. When removing this nut, gently hold the
fan blade, and turn the nut clockwise. If one of the blades becomes deformed, it may be bent back into shape using
a flat surface as a reference.
A flat washer is located on the motor shaft between the snap ring on the shaft and the fan blade.
NOTE: If the fan blade is bent and motor vibrations increase, the noise made by the fan will be greater.
MOUNTING PLATE OVEN
The fan motor on the rear of the unit is mounted to the main back (with three screws). There is a mounting plate held
in place between the main back (with 2 screws) and the rear oven wall (with 2 screws). Should it be necessary to replace
the oven cavity, you must remove the 2 screws located inside the unit at the rear of the oven cavity.
FAN MOTOR
The 120 volt fan motor is located on the outside of the rear of the oven.

FAN RELAY
The fan motor runs continuously while in the convection mode unless the door is opened. If the fan does not operate,
check the following:
• Fan icon on display.
• Voltage output between terminals P5-7 and neutral (120v).
• 120 Volts available at fan motor.
• Fan motor coil resistance 35 ohms ± 10%.
• Door/light switch.
DOOR LOCK MECHANISM
The appliance is equipped with an electronic oven control and has an auto locking door latch feature. When the self
clean cycle is programmed, the door is locked by a motor operated latch system. The interior of oven does'nt need to
heat up to 520°F before the door locks. However, until the temperature inside oven reaches 520°F, the self-clean
program can be canceled and door will unlock immediately. After oven reaches temperatures over 520°F, the door will
not unlock until temperature drops below 490°F.
OVEN DOOR REMOVAL AND REPLACEMENT
1. Disconnect range from electrical supply
2. Open door to fully opened position.
3. Pull up the lock located on each hinge support and engage it in the hook of the hinge lever. You may have to apply
a little downward pressure on the door; pull the locks fully over hooks.
4. Grasp door by sides, pull bottom of door up and toward you while rotating the top of door toward range to
completely disengage the hinge levers.
5. To reinstall reverse procedure. Make sure hinge supports are fully engaged before unlocking the hinge levers.

WARM AND SERVE DRAWER (SOME MODELS)
The Warm and Serve Drawer is designed to keep prepared food warm until it is time to serve.
This feature is available on select gas and electric models. The Warm and Serve Drawer is
electrically operated on both gas and electric models.
Ranges featuring the Warm and Serve Drawer feature are equipped with heavy duty ball bearing
drawer glides. These glides not only support the weight more effectively, they also allow the
drawer to be opened to its full depth.
The warmer control is an infinite heat switch mounted to the control panel. A 450 watt, 120 volt
element is secured to a metal base located just below the Warm and Serve Drawer. A preheat thermostat (bimetal
disk) is located at the left rear corner of the range, directly above the element terminals. The system also contains a
diode, indicator lamp, and safety thermostat. The diode is located in the wiring harness a short distance from the
safety thermostat.
The safety thermostat is mounted to the rear insulation panel and is actuated during the self-clean cycle. It is used to
open the circuit to the heating element so the warming drawer will not function during the self-clean cycle.

WARM AND SERVE DRAWER COMPLETE CIRCUIT (SOME MODELS)
When the temperature at the preheat thermostat reaches 130°F the thermostat opens. This forces the current to flow
through the parallel circuit which contains the diode. The diode allows only half power (every other pulse of electric-
ity or pulsating DC) to flow through the element, resulting in lower heat output by the element. The infinite heat
control switch will cycle as necessary to maintain the temperature in the drawer as indicated by the control switch
setting. If the control is placed on a lower setting, it is possible for the temperature in the drawer to drop enough to
allow the preheat thermostat to close again which will allow the element to reenter the "Preheat" mode at full
power.
WARM AND SERVE DRAWER PREHEAT CIRCUIT (SOME MODELS)
When the Warm and Serve Drawer is first turned on, a "Preheat" circuit is established to provide full power (120
volts) through the lock switch, L1 to H1 of the warmer switch, the warmer element and the preheat thermostat.
WARM AND SERVE DRAWER AFTER CUT-OUT CIRCUIT (SOME MODELS)
An indicator lamp wired in parallel with the element is illuminated whenever the control switch is turned on.
