This service data sheet is intended for use by persons having electrical and mechanical training and a level of
knowledge of these subjects generally considered acceptable in the appliance repair trade. The manufacturer
cannot be responsible, nor assume any liability, for injury or damage of any kind arising from the use of
this data sheet.
To avoid the possibility of personal injury and/or property damage, it is important that safe servicing practices be
observed. The following are some limited examples of safe practices.
1. Do not attempt a product repair if you have any doubts as to your ability to complete it in a safe and satisfactory
manner.
2. Before servicing or moving an appliance, remove power cord from electric outlet, trip circuit breaker to Off, or
remove fuse.
3. Never interfere with the proper installation of any safety device.
4. USE ONLY REPLACEMENT PARTS CATALOGED FOR THIS APPLIANCE. SUBSTITUTIONS MAY DEFEAT COMPLIANCE
WITH SAFETY STANDARDS SET FOR HOME APPLIANCES.
5. GROUNDING: The standard color coding for safety ground wires is GREEN OR GREEN WITH YELLOW STRIPES.
Ground leads are not to be used as current carrying conductors. IT IS EXTREMELY IMPORTANT THAT THE SERVICE
TECHNICIAN REESTABLISH ALL SAFETY GROUNDS PRIOR TO COMPLETION OF SERVICE. FAILURE TO DO SO
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 uninsulated 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.

FIRST RISE
It is normal to see a temperature overshoot in the
first rise of all modes when you monitor the temperature.

OVEN CALIBRATION
Set the electronic oven control for normal baking at 350°F/176°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.
During a normal bake mode, the control preheats the oven with the bake element. When the desired temperature
is reached, the control will cycle approximately between 12% of time in Broil and 85% of time in Bake. Both elements
use full power when they are on but they are never on at the same time.
NORMAL BAKE
CLEAN
ES300 ELECTRONIC OVEN CONTROL
The ES300 electronic oven control is almost identical to the current control with a few exceptions.
During a cleaning process, the oven uses the bake element. When this mode is called, the door locks right after start
button is pushed.
Note: The ES300'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).

Note: Only three fault codes are displayed by this control “F1”, “F3”, and “F9”. Generally speaking “F1” implies
a control failure, “F3” an oven probe problem, and “F9” a latch motor problem. In all ocurrences the alarm is
accompanied by a display of “F1”
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.
1. Door motor failure / jammed. Latch
motor switch failure.
2. Control software failure, or
component failure (relay stuck).
3. Safety thermostat opened, or cooling
fan stalled.
4. Wiring Problem.
Likely Failure Condition/Cause Suggested Corrective Action
Fault Code
1. Disconnect power, wait 30 seconds and reapply power. If
fault returns upon power-up, replace EOC.
2. 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. Check wiring in probe circuit for possible open condition.
Check RTD resistance at room temperature (compare to
probe resistance chart). If resistance does not match the
chart, replace the RTD sensor probe.
2. Check wiring in probe circuit for possible 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.
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. Look for stalled cooling fan, broken
safety thermostat, shorts or opens.
4. Unplug Latch Motor terminal from the timer side, apply
power (L1) directly to the Lock Motor, if the motor does not
rotate, replace Lock Motor Assembly. Plug Latch Motor
terminal.
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.
