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/CLEAR to end bake mode.

Temperature Adjustment

1.Set EOC to bake at 550°F.

2.Within 5 seconds of setting 550°F, press and hold the bake pad for approximately 15 seconds until a single beep is heard (longer may cause F11 shorted keypad alarm).

3.Calibration offset should appear in the display.

4.Use the slew keys to adjust the oven temperature up or down 35°F in 5°F increments.

5.Once the desired (-35° to 35°) offset has been applied, press STOP/CLEAR.

Note: Changing calibration affects normal Bake mode. The adjustments made will not change the Self-Cleaning cycle temperature.

		may require the entire oven to be replaced should damage be extensive.
F12	Bad Micro Identification.	2. (F11, 12 & 13) Disconnect power, wait 30 seconds and reapply power.
		3. (F11, 12 & 13) If fault returns upon power-up, replace EOC.
F13	Bad EEPROM Identification/Checksum error.

F30	Open probe connection.	1. (F30 or F31) Check resistance at room temperature & compare to RTD Sensor resistance chart.
F31	Shorted Probe connection.	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.
F40	Cooktop Lockout error (some models).	1.	(F40) Check the wiring.
		2.	(F40) Replace the Cooktop Lockout Control Board.
		3. (F40) Replace EOC.
F90	Maximum oven door unlock time exceeded.	1. (F90, 91, 92, 93 & 94) Check the wiring between EOC & Lock Motor Micro Switch.
F91	Maximum oven door unlock attempts exceeded.	2.	(F90, 91, 92, 93 & 94) Replace the Motor Door Latch assembly if necessary.
		3. (F90, 91, 92, 93 & 94) Check for binding of the Latch Cam, Lock Motor Rod & Lock Motor Cam.
F92	Maximum oven door open time exceeded.	4.	(F90, 91, 92, 93 & 94) Check to see if Lock Motor Coil is open. If open, replace Lock Motor
		Assembly.
F93	Maximum oven door lock time exceeded.	5. (F90, 91, 92, 93 & 94) Lock Motor continuosly runs - if Micro Switch is open, replace Lock Motor
		Assembly.
F94	Maximum oven door lock attempts exceeded.	6. (F92, 93 & 94) Check oven door Light Switch - if open, replace Switch.
		7.	If all situations above do not solve problem, replace EOC.
