failure
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 TSTpanel.
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 TSTpanel.
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 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.
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
harnessas 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.
