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
examples, but without limitation, of such practices.
1. Before servicing or moving an appliance remove power cord from electrical
outlet, trip circuit breaker to OFF, or remove fuse.
2. Never interfere with the proper installation of any safety device.
3. 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 safety hazard.
4. 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.
Oven Calibration/ Temperature adjustment - See Use & Care Guide.
Note: Changing calibration affects normal Bake mode. The adjustments made will not
change the Self-Cleaning cycle temperature.

Tech Sheet Abbreviations and Terminology
ESEC = Electronic Surface Element Control TST = Touch Sensor Technology (touch control glass panel)
TSEC = Touch Sensor Electronic Control RTD = Resistance Temperature Device. (Temp Probe or Temp Sensor)
PS = Power Supply board (PS1 , PS2, etc.)
TCO = Thermal Cut Out also "Thermo Disc" or "Thermal Limiter"
Suggested Corrective Action
1. Check RTD Sensor Probe using the RTD scale found in the tech sheet.
Replace if defective.
2. If oven is overheating disconnect power from the range and unplug connector P1 from power
supply board. Reapply power to the range. If oven continues to heat when the power is
reapplied, replace the oven relay board.
3. Replace the EOC.
NOTE: Severe overheating may require the entire oven to be replaced should damage be
extensive.
1. Reset power supply to range to see if failure code will clear.
2 Test ribbon harness and connectors between the TST panel and EOC. Replace if defective.
3. Replace the TST panel.
4. Replace the EOC.
Disconnect power, wait 30 seconds and reapply power. If fault returns upon power-up, replace
EOC.
1.Test ribbon harness and connections between TST panel and EOC. Replace if defective
2. Replace the TST panel.
3. Replace the EOC.
1. Test the harness and connections from EOC connector P16 to oven relay board J2.
2. Replace the oven relay board.
3. Replace the EOC.
1. Test wiring harness and connections between EOC connector P2 and ESEC 30 UIB P9.
2. Test wiring harness and connections between PS board 1 (P3) and ESEC 30 UIB connector
P6.
3. Test for approximately 9 volts DC output from PS board 1 at ESEC 30 UIB connector P6, pins
1 & 2. If output voltage is incorrect test incoming power supply to PS board 1 at harness
connector P1 pins 1 & 4. If incoming power is correct (120 VAC), replace PS board 1. If output
voltage is correct replace ESEC 30 UIB.
4. Replace EOC.
1. Check harness and connections between VSC board and EOC.
2. Test for approximately 5 volts DC to VSC board at P6 connector pins 1 & 6. If voltage is correct
replace VSC board. If voltage is incorrect replace EOC.
1. (F30 or F31) Check resistance at room temperature & compare to RTD Sensor resistance
chart. If resistance does not match the RTD chart replace RTD Sensor Probe. Check Sensor
wiring harness between EOC & Sensor Probe connector.
2. (F30 or F31) Check resistance at room temperature, if less than 500 ohms, replace RTD
Sensor Probe. Check for shorted Sensor Probe harness between EOC & Probe connector.
If latch motor does not run when clean cycle is selected:
1. Check to see if latch motor coil is open. If open, replace latch motor assembly.
2. Test for 120 volts to the terminals of the latch motor. If voltage is correct and motor does not
run replace
latch motor assembly. If voltage is not correct replace EOC.
If latch motor runs when clean cycle is selected:
1. Check the wiring harness between EOC & latch motor switch. Repair or replace harness as
needed.
2. Test operation of the switch contacts. Replace latch motor assembly if defective.
3. Check for binding of the latch cam, latch motor rod & latch motor cam.
4. If all situations above do not solve problem, replace EOC.
