ERC DIAGNOSTIC TESTSTrueTempSSEO ETN TDELAY BAKE CLEANSTART CLOCK CLEANBROIL LOCKED DOORCOOK STOP TIMERERC ON BOARD DIAGNOSTIC TESTSThis test allows the Technician to energize the bake and broilrelays (listen for A click), use the ovens onboard temperaturesensing and control system to measure oven temperature(sensor, connector and ERC diagnosis) and lastly it allows you totest keypanel input responses.HOW TO ENTER AND EXIT THE DIAGNOSTIC MODETo perform the ERC diagnostic tests, follow the steps below:1.2.3.To initiate the ERC test mode, first remove power to theappliance for approx. 8 seconds and then reapply power.Simultaneously press the COOKING TIME, DELAY STARTand number 8 pads. The word "tESt" will appear in theERC display. NOTE: If no keypad entry is made within 5minutes, the ERC test mode will "time out".To terminate the ERC test mode, press the CLEAR / OFFkey pad.HOW TO PERFORM THE TESTSThe following tests allow you to quickly varify various ERC andkeypanel functions. Listed below are four common diagnostictests that can be made directly from the ERC.BakeCircuitTest1SETDELAYBROILONBAKE CLEANLOCKED DOORSETSTARTCOOKCLOCKSTOPCLEANTIMER1 ENERGIZE BAKE CIRCUIT - To perform this test, press BAKEthen START and listen for the bake relay to energize. CAUTION:If you hold the start pad in, you are energizing the BAKE circuit.As soon as you release the START pad the relay will deenergize.If the relay does not energize, check the following: reconfirm thatyou have entered the test mode correctly, check power andwiring connections to the ERC, and lastly suspect a faulty ERC.NOTE: when performing this test, the glowbar will be energizedas long as you hold in the start pad.BroilCircuitTestSensorTestNumericKey PadTest234SETDELAYBROILSETDELAYBROILSETDELAYBROILONBAKE CLEANLOCKED DOORONBAKE CLEANLOCKED DOORONLOCKED BAKE CLEANDOORSETSETSTARTCOOKSTARTCOOKCLOCKSTOPCLOCKSTOPCLEANTIMERDisregard these 4 digits as they haveno relavance on the sensor test.oSETOven temperatureSTARTCOOKCLOCKSTOPCLEANTIMERCLEANTIMERExample: Number 5 key pad depressed2 ENERGIZE BROIL RELAY - To perform this test, press BROILthen START and listen for the broil relay to energize. CAUTION: Ifyou hold the start pad in, you are energizing the BROIL circuit.As soon as you release the START pad the relay will deenergize.If the broil relay does not energize, check the following: reconfirmthat you have entered the test mode correctly, check power andwiring connections to the ERC, and lastly suspect a faulty ERC.NOTE: when performing this test, the glowbar will be energizedas long as you hold in the start pad.3 SENSOR TEST - To perform this test, press and hold theCOOKING TIME pad or DELAY START pad (vaies by model).The oven temperature will show in the display. NOTE: oventemperatures below 100°F. will show as 100°F. If thetemperature showing in the display is not correct then suspect thefollowing: calibration, sensor, sensor connection, or ERC.4 NUMERIC KEY PADS TEST - To perform proper numeric keypanel input responses, press any numbered key pad and hold it infor approximately 5 seconds; the number you are pressing wilshow in the ERC display. If it does not, reconfirm that you haveentered the test mode correctly, check wiring connections to theERC and keypanel, and lastly confirm shorted or open key pad byperforming the Key Panel test on page 10.– 18 –
LOCK MOTOR CIRCUIT5 LOCK MOTOR CYCLE TEST - The lock motorcycle test allows you to run the latch assembly throughone complete cycle of operation, testing motoroperation and front & rear latch switch contacts. Toperform this test, push and hold the SELF CLEAN keypad - make sure that the oven door is closed (lightswitch depressed). While depressing the SELFCLEAN pad the lock motor will run through a completecycle. Watch the ERC display closely as it will change,based on the location of the motor and the position(open or closed) of the latch switches.Illustrations A, B, C, and D show the sequence ofevents that will occur during the complete lock motorcycle, as well as what will be seen in the ERC display.Notice that the numbers shown in the left side of thedisplay represent the position of the lock motor as wellat the contact positions (open or closed) of the latchswitches.ABCDASETDELAYBROILSETDELAYBROILSETDELAYBROILSETDELAYBROILSETDELAYBROILBAKELOCKEDBAKELOCKEDBAKELOCKEDBAKELOCKEDBAKELOCKEDONCLEANDOORONCLEANDOORONCLEANDOORONCLEANDOORONCLEANDOORSETSETSETSETSETSTARTCOOKSTARTCOOKSTARTCOOKSTARTCOOKSTARTCOOKCLOCKSTOPCLOCKSTOPCLOCKSTOPCLOCKSTOPCLOCKSTOPCLEANTIMERCLEANTIMERCLEANTIMERCLEANTIMERCLEANTIMERUNLOCKED POSITIONRear switch contacts openFront switch contacts closedMoving toward LOCKEDRear switch contacts openFront switch contacts openLOCKED POSITIONRear switch contacts closedFront switch contacts openMoving toward UNLOCKEDRear switch contacts openFront switch contacts openReturn to UNLOCKED POSITIONRear switch contacts openFrontcontacts closedDOOR LATCH MECHANISMThe latch mechanism is thermally Controlled.When the SELF CLEAN cycle is selected and theoven sensor senses a temperature between 560°Fand 650°F, the ERC supplies power to the lockmotor, driving the motor towards the LOCKEDposition. When the lock motor reaches theLOCKED position, the micro-switches on the lockmechanism signal the control board to stop themotor, leaving it in the LOCKED position.When the oven sensor senses a temperature ofapproximately 300°F. the control board once againsupplies power to the lock motor, driving it towardsthe UNLOCKED position. When the UNLOCKEDposition is reached, the micro-switches on the lockmechanism signal the control board to stop themotor, leaving it in the UNLOCKED position.ContactsOpenContactsClosedUNLOCKED modeRearRearFrontContactsClosedALOCK MOTOR CYCLECContactsOpenContactsOpenMoving toward LOCKEDmodeBRearRearFrontContactsOpenDLOCK MOTOR ACCESSRemove the cooktop following the steps outlinedon page 5 of this <strong>service</strong> <strong>guide</strong> - TO RAISE ORREMOVE COOKTOP.Next remove the lock motor cover to gain access tothe lock motor assembly.FrontContactsOpenLOCKED modeFrontContactsOpenMoving toward UNLOCKEDmodeLOCK MOTORCOVERLOCK MOTORLatch circuit shown inUNLOCKED modeOven Temp.Sensor1100W at 75 o F.2634W at 865 o F.FRONTLatch SwitchREARLatch SwitchNCNOWWCOMCOMF2F15 1 YO YS– 19 –
