SERVICE DATA SHEET
Gas Range with ES 536/586 Electronic Oven Control
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
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 extreme-
ly 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
Set the electronic oven control for normal baking at 350°F. Obtain an
average oven temperature after a minimum of 5 cycles. Press STOP or
CLEAR keypad to end Bake mode.
Temperature Offset Adjustment
See Owner's Manual
Note: Changing calibration affects all Baking modes. The adjustments
made will not change the self-cleaning temperature.

ELECTRONIC OVEN CONTROL (EOC) FAULT CODE DESCRIPTIONS
Suggested Corrective Action
If Oven is cold:
1. If fault code is present with cold oven test oven temperature sensor probe circuit resistance. Use RTD scale found in the
tech sheet.
2. Replace probe or repair wiring connections if defective.
3. If temperature sensor probe circuit is good but fault code remains when oven is cold replace the EOC.
If Oven is overheating:
1. If oven is severely overheating/heating when no cook cycle is programmed test oven temperature sensor probe circuit
resistance using the RTD scale found in the service tech sheet. Also verify that the temperature sensor probe in properly
installed in the oven cavity.
2. Disconnect power from the range, wait 30 seconds and reapply power. If oven continues to heat when the power is
reapplied, replace the EOC. NOTE: Severe overheating may require the entire oven to be replaced should damage be
extensive.
1. Reset power supply to range - Disconnect power, wait 30 seconds and reapply power.
2. Check/reseat ribbon harness connections.
3. Replace the EOC.
Disconnect power, wait 30 seconds and reapply power. If fault returns upon power-up, replace EOC.
Disconnect power, wait 30 seconds and reapply power. If fault returns upon power-up, replace EOC.
Disconnect power, wait 30 seconds and reapply power. If fault returns upon power-up, replace EOC.
Check resistance at room temperature & compare to RTD Sensor resistance chart. If resistance is correct replace the EOC. If
resistance does not match the RTD chart replace RTD Sensor Probe. Check Sensor wiring harness between EOC & Sensor
Probe connector.
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 resistance is correct replace the EOC.
1. The error is triggered if the meat probe sees a temperature in excess of 392°F. Make sure the meat probe was not used
in such way that it could have seen such temperature. If the tip of the probe is not inserted in the meat it will see the
cavity temperature, which can be higher than 392°F (depending on the setpoint) and trigger the alarm.
2. When the meat probe is connected to the socket inside the oven cavity, if the meat probe is not fully inserted into the
socket it may short the contacts and cause the error. Make sure the probe is inserted as much as it can.
3. Verify meat probe resistance at room temperature. Compare to meat probe resistance chart. If the meat probe does not
match the chart, replace it.
4. If the above steps failed to correct the problem, replace the oven relay board.
1. Verify proper assembly of backguard panel. Check for damaged or loose panels, brackets, endcaps, etc.
2. Check for blocked ventilation slots in control panel rear cover.
3. Inspect oven vent for proper assembly and air flow.
4. Verify operation of cooling fan (if present).
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 assembly 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.
Disconnect power, wait 30 seconds and reapply power. If fault returns upon power-up, replace EOC.
