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. Please
note: Changing calibration affects normal Bake mode. The adjustments made will not
change the Self-Cleaning cycle temperature.
Suggested corrective action
1. Check / re-install ribbon at J3 connection on the ESEC 30 UIB.
2. Replace ESEC 30 UIB.
3. Replace TST panel.
1. Check / re-install ribbon at J3 connection on the ESEC 30 UIB.
2. Replace ESEC 30 UIB.
3. Replace TST panel.
Turn power off to appliance for 30 seconds - then reapply power.
Does error return within 5 seconds after reapplying power?
If YES then: Use Solution A shown below.
If NO then: Does error return after 30 seconds?
If YES then: Use Solution B shown below.
If NO then: Test operation. If error does not return then the condition was corrected by the power reset.
Solution A: E14 failure; key reads ribbon cable is disconnected or defective:
1. Check / reinstall ribbon at J4 connection on ESEC 30 UIB.
2. Replace ESEC 30 UIB.
3. Replace TST panel.
Solution A: E15 failure; ESEC error or signal loss between ESEC30 UIB & relay board:
1. Check harness and connections between connector P6 or ESEC30 UIB to connector J2 of ESEC realay
board. Repair or replace harness as needed.
2. If connection and harness are good then replace ESEC relay board.
3. If error remains then replace ESEC30 UIB.
4. If previous steps do not resolve the failure replace the TST panel.
Solution B: - E11 failure; shorted keypad:
1. Reset power supply to appliance and see if failure code clears.
2. Check / re-install reibbon harness and connectors between the TST panel and ESEC 30 UIB.
3. Replace the TST panel.
4. Replace the ESEC 30 UIB.
1.Correct wiring of that element and its hot surface limiter.
1. With power disconnected, check continuity of hot surface limiter contacts (1b-2b) at that element's
terminalblock.contacts are closed even when the surface is cold replace element.
2. If hot surface limiter contacts (1B-2B) are open replace power board.
1. With power disconnected, check continuity of hot surface limiter contacts (1b-2b) at that element's
terminalblock.contacts are closed even when the surface is cold replace element.
2. If hot surface limiter contacts (1B-2B) are open replace power board.
1. Check the wire harness connector and seat properly to Relay Board J4 connector.
2. Check surface harness for correct wiring from each element's hot surface limiter - correct wiring or replace
harness if necessary.
3.Turn on all elements to Hi. Wait 3 minutes to ensure all surfaces are hot. Check continuity of limiter switch
circuit for each element. If circuit is open replace that surface element. NOTE: Limiter contacts can be
tested through the harness on Relay Board connector J4
4.Check the wire harness and connectors from ESEC 30 UIB P5 to Relay Board Connector J5. Replace
harness if defective.
5. Replace Relay Board.
6. Replace ESEC 30 UIB.

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 dsiconnect 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.

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 ESEC 30 UIB and ESEC 20 relay board.
3. Test wiring harness and connections between PS board 2 (P2) and ESEC 30 UIB connector P7
4. Test for approximately 9 volts DC output from PS board 2 at ESEC 30 UIB connector P7, pins 1 & 5. If
output voltage is incorrect test incoming power supply to PS board 2 at harness connector P1 pins 1 & 4. If
incoming power is correct (120 VAC) replace PS board 2. If output voltage is correct replace ESEC 30 UIB
5. Replace 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:

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.
