1 TECH SHEET - DO OT DISCAD PAGE 1 DIAGOSTICS Before servicing, perform the following checks: The most common cause for control failure is corrosion on connectors. Therefore, disconnecting and reconnecting wires will be necessary throughout test procedures. All tests/checks should be made with a VOM or DVM having a sensitivity of 20,000 ohms per volt DC or greater. Check all connections before replacing components, looking for broken or loose wires, failed terminals, or wires not pressed into connectors far enough. Voltage checks must be made with all connectors attached to the boards. esistance checks must be made with power cord unplugged from outlet, and with wiring harness or connectors disconnected. Is oven in Sabbath Mode? If so SAB will appear in the digital display. Press and hold 6 key for 5 seconds to end Sabbath Mode. POBLEM: Bake Temperature eeds Adjustment 1. Press BAKE pad for 5 seconds. The default temp. 0 or a previously entered offset temp. will show in the Temp. Display. Press the TEMP pad up arrow ( ) to increase the temperature in 5 F or 3 C increments. Press thetemp pad down arrow ( ) to decrease the temperature in 5 F or 3 C increments. Maximum offset temperature adjustment is ±35 F or ±21 C. 2. Press the STAT pad to save the temp. adjustment. IMPOT Electrostatic Discharge (ESD) Sensitive Electronics ESD problems are present everywhere. ESD may damage or weaken the electronic control assembly. The new control assembly may appear to work well after repair is finished, but failure may occur at a later date due to ESD stress. Use an anti-static wrist strap. Connect wrist strap to green ground connection point or unpainted metal in the appliance -O- Touch your finger repeatedly to a green ground connection point or unpainted metal in the appliance. Before removing the part from its package, touch the anti-static bag to a green ground connection point or unpainted metal in the appliance. Avoid touching electronic parts or terminal contacts; handle electronic control assembly by edges only. hen repackaging failed electronic control assembly in anti-static bag, observe above instructions. Fahrenheit ( F) to Celsius ( C) Conversion The default is Fahrenheit ( F). 1. Press the BOIL pad for 5 seconds. The temperature will be displayed in degrees Celsius indicated by the C in the temperature display. 2. To return the display to degrees Fahrenheit press the BOIL pad again for 5 seconds. F will show in the temperature display. Programming the Cavity Size hen replacing the electronic control, be sure to program the cavity size within 60 seconds of power up by pressing the following keys: BAKE (upper half of BAKE key), COVECTIO BOIL (lower half of BOIL key), STOP TIME, COV FULL MEAL, digit 7, digit 9, TIME SET/STAT, STAT. 1. Size is shown in display - ID Press CLOCK SET/STAT until correct size is displayed. 3. Press CACEL key (do not press the OVE STAT key). 4. Press and hold 1 key for 5 seconds to verify programming.

Upon replacement, immediately return old electronic oven control using the mailing label supplied with each new control. For double ovens, the failure code is displayed on the side of the display that corresponds to the oven with the faulty part (upper oven = left side of display).

Check sensor connection. 2. Measure sensor resistance (1080Ω at 21 C[70 F]. Add 2Ω per degree F.) 3. If resistance is not valid, replace sensor. 4. If sensor resistance and connections are good, then the oven cavity temperature must have exceeded a safe level. Check for welded-closed relays on the control. F4 E1 Meat probe malfunction - shorted 1. Disconnect meat probe and measure probe resistance (78kΩ at 15.6 C[60 F]; 37kΩ at 32.2 C[90 F]). 2. If resistance is not valid, replace probe. 3. Insert probe and check for a firm connection between probe and jack (in oven cavity). 4. Check connection between jack and harness (in rear of oven). F5 E0 E1 E5 E7 Door is open, but latch is locked (condition exists when door switch is closed indicating an open door and latch switch is closed indicating a locked door) Self clean latch will not lock Self clean temperature (288 C [550 F]) not reached within 45 minutes Self clean latch will not unlock 1. Check the Latch Assembly: - Check latch arm pivot joint, arm/solenoid connection, solenoid spring, and spring washer. 2. Check the Latch Solenoid: - Check for firm electrical connections. - Disconnect the two wires from the solenoid and measure the resistance of the solenoid. A small resistance (approx. 175Ω) is normal. If the solenoid is open ( Ω) or shorted (0Ω), it should be replaced. 3. Check the Latch Switch. Disconnect it and use a continuity tester: - Door latched = switch closed, continuity should read 0Ω. - Door unlatched = switch open, continuity should read Ω. 4. Check Door Open/Closed Switch. Disconnect it and use a continuity tester: - Door open = switch closed, continuity should read 0Ω. - Door closed = switch open, continuity should read Ω. 5. Check power and element connections.
