SERVICE DATA SHEET Gas ranges with ES 330 electronic oven control (some models with cooktop lockout) 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/ Clear or Cancel 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 Press Stop/ Clear or Cancel. Note: Changing calibration affects normal Bake mode. The adjustments made will not change the Self-Cleaning cycle temperature. COOKTOP LOCKOUT (some models) For some models it may be necessary to unlock the cooktop before servicing. If the Cooktop Locked Indicator Light is ON then the cooktop has been locked. To turn the Cooktop Lockout Feature OFF: 1. BE SURE ALL GAS SURFACE BURNER CONTROLS ARE SET TO THE OFF POSITION. 2. Press & hold oven light until one beep is heard (after 3 seconds). The Cooktop Locked indicator light will turn OFF and the gas surface burners may be used normally. To turn the Cooktop Lockout Feature ON: 1. BE SURE ALL GAS SURFACE BURNER CONTROLS ARE SET TO THE OFF POSITION. 2. Press & hold oven light until one beep is heard (after 3 seconds). The Cooktop Locked indicator light will turn ON and the gas surface burners and functions are locked out until the cooktop is unlocked.

NOTE: The valve lockout motor is very quiet. Under normal conditions the motor can not be heard when it is running. Suggested Corrective Action Check RTD Sensor Probe & harness. Replace if necessary. If oven is overheating, disconnect power. If oven continues to overheat when the power is reapplied, replace EOC. Severe overheating may require the entire oven to be replaced should damage be extensive. 1. Disconnect power, wait 30 seconds and reapply power. 2. If fault returns upon power-up, replace EOC. 1. 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. Check resistance at room temperature, if less than 500 ohms, replace RTD Sensor Probe. Check for open or shorted Sensor Probe harness between EOC & Probe connector. IF VALVE LOCKOUT MOTOR RUNS: 1. Test valve lock microswitch. If defective replace valve assembly 2. Test harness from valve lock microswitch to Cooktop Lockout Board and from Board to EOC. Repair Replace if defective 3. Replace Cooktop Lockout Board 4. Replace EOC F90 Maximum oven door unlock time exceeded. F91 Maximum oven door unlock attempts exceeded. F92 Maximum oven door open time exceeded. F93 Maximum oven door lock time exceeded. F94 Maximum oven door lock attempts exceeded. IF VALVE LOCKOUT MOTOR DOES NOT RUN: 1. Test valve lock motor windings. If open replace valve assembly 2. Test for line voltage to valve lock motor. If voltage is correct replace valve assembly. 3. Test harness from Cooktop Lockout Board to valve lock motor and from Cooktop Lockout Board to EOC. Repair / Replace if defective. 4. Replace Cooktop Lockout Board. 5. Replace EOC. IF LATCH MOTOR RUNS: 1. Check the wiring between EOC & Lock Motor Micro Switch. 2. Check the contacts of Micro-Switch on latch motor assembly. If contacts are open when motor cam depresses switch, replace Lock Motor Assembly. 3. Check for binding of the Latch Cam, Lock Motor Rod & Lock Motor Cam. 4. If all situations above do not solve probem, replace EOC. IF LATCH MOTOR DOES NOT RUN 1. Check to see if Lock Motor Coil is open. If open, replace Lock Motor Assembly. 2. (F92, 93 & 94) Check oven door Light Switch - if open, replace Switch. 3. If all situations above do not solve probem, replace EOC.
