SERVICE DATA SHEET 318047410 (0205) Rev. C
Gas & Electric Wall Ovens with Electronic Oven Control (ES 300)
NOTICE
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.
SAFE SERVICING PRACTICES
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 and gas connections are correct and secure.
• All gas connections are tested for leaks. DO NOT TEST FOR GAS LEAKS WITH A FLAME.
• 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.
ES300 ELECTRONIC OVEN CONTROL
The ES300 electronic oven control is almost identical to the current control with a few exceptions.
Note: The ES300's are not field repairable. Only temperature settings can be changed. See Electronic Oven Control
Guide (section recalibrating your oven temperature)
Note: Depending on model, the size and shape of touch pads may vary (for example elliptical instead of round).
NORMAL BAKE
During a normal bake mode, the control preheats the oven with the bake element. When the desired temperature
is reached, the control 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.

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”
Likely Failure Condition/Cause
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.
Fault Code Suggested Corrective Action
1. Replace EOC.
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. 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.
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 Door Switch
circuits.
4. Unplug P4, apply power (L1) directly to the Lock Motor, if the
motor does not rotate, replace Lock Motor Assembly. Plug P4.
5. Check Lock Switch A 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 Switch. If the Lock Switch
is defective, replace Motor Lock Assembly.
6. If all above steps fail to correct situation, replace control.

CLEAN
During a cleaning process, the oven uses the bake element. When this mode is called, the door locks right after 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.

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 500°F/260°C before the door locks. However, until the temperature inside oven reaches 500°F/260°C, the
self-clean program can be canceled and door will unlock immediately. After oven reaches temperatures over 500°F/
260°C, the door will not unlock until temperature drops below 500°F/260°C.
