SERVICE DATA SHEET

Electric Range with ES 540 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 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

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 Adjustment

1.While in a non-cooking mode, press and hold the BAKE key pad for 6 seconds.

2.The current calibration offset (temperature adjustment) should appear in the temperature display.

3.Use the number key pads (0-9) to enter the desired amount of adjustment (up to 35°F).

4.Press SELF CLEAN key pad to change the sign of the adjustment to a (-) if necessary. A positive adjustment will not display a sign.

5.Once the desired adjustment (-35° to 35° F) has been entered, press the START key pad to accept the change or the STOP/CLEAR/ CANCEL key pad to reject the change.

Note: Changing calibration affects all Baking modes. The adjustments made will not change the self-cleaning temperature.

Electonic Oven Control Fault Code Descriptions

Fault Code	Likely Failure Condition/Cause		Suggested Corrective Action
F10	Runaway Temperature.	1. (F10 only) Check RTD Sensor Probe & replace if necessary. If oven is overheating, disconnect
		power. If oven continues to overheat when the power is reapplied, replace EOC. Severe
F11	Shorted Keypad.	overheating may require the entire oven to be replaced should damage be extensive.
		2.	(F11, 12 & 13) Disconnect power, wait 30 seconds and reapply power.
F12	Bad Micro Identification.	3.	(F11, 12 & 13) If fault returns upon power-up, replace EOC.
F13	Bad EEPROM Identification/Checksum error.
F20	Communication failure between EOC & ESEC system	1.	Test harness/connections P4 (EOC) & P7 (Surface Element Control Board)
	(for electric range models ONLY)	2. If harness checks O.K. failure can be caused by faulty UIB, Surface Element Control Board
		or EOC.
F26	Communication failure with Mini Oven Control Board.	1.	Check harness & connectors from the EOC to Mini Oven Control Board. Check for 15VDC
	(for models equipped with Bake-n-Warm™ ONLY)	to Mini Oven Control Board (red & gray wires). If harness and voltage are good replace Mini Oven
		Control Board. If fault returns replace the EOC.
F30	Shorted Probe connection.	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
F31		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.
F90	Maximum oven door unlock time exceeded.	1. (F90) Check the wiring between EOC & Lock Motor Micro Switch.
		2.	(F90) Replace the Motor Door Latch assembly if necessary.
F91	Maximum oven door unlock attempts exceeded.	3.	(F90) Check for binding of the Latch Cam, Lock Motor Rod & Lock Motor Cam.
		4.	(F90) Check to see if Lock Motor Coil is open. If open, repl;ace Lock Motor Assembly.
F92	Maximum oven door open time exceeded.	5.	(F90)Lock Motor continuosly runs - if Micro Switch is open, replace Lock Motor Assembly.
		6.	(F90) Check oven door Light Switch - if open, replace Switch.
F93	Maximum oven door lock time exceeded.	7.	If all situations above do not solve probem, replace EOC.
F94	Maximum oven door lock attempts exceeded.
F95	Door Latch
