For each Fault code there is a listing of the likely failure condition or cause, as well as suggested
corrective actions to be taken. Perform the steps one at a time in the order listed below to correct the
specific failure condition.
Note: Fault codes are not a foolproof system. Never assume that a part has failed based on a displayed fault
code. An example would be if the eoC is displaying F30 (open sensor), the failure could be caused by a loose
connection or faulty wire harness between the eoC and sensor or the sensor could simply be unplugged.

ELECTRONIC OVEN CONTROL
FAILURE/FAULT CODES (ES630)
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 1. 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. Check/reseat ribbon harness connections between TST panel and EOC.
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. Check/reseat ribbon harness connections between TST panel and EOC.
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 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 8 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 lock motor runs:
1. Test continuity of wiring between EOC and lock switch on lock motor assy. Repair if needed.
2. Advance motor until cam depresses the plunger on lock motor switch. Test continuity of switch contacts.
If switch is open replace lock motor assy.
3. If motor runs and switch contacts and wiring harness test good, replace the EOC
If lock motor does not run:
1. Test continuity of lock motor windings. Replace lock motor assy if windings are open.
2. Test lock motor operation by using a test cord to apply voltage. If motor does not operate replace lock
motor assy.
3. If motor runs with test cord check continuity of wire harness to lock motor terminals. If harness is good
replace the EOC.
