– 41 –• As the cam revolves about 1/2 rotation(approximately 12 seconds), it moves the lockhook into a corresponding slot in the oven doorto secure it.• The movement of the cam closes lock switch 1,which tells the control the door is locked. Thecontrol then removes power from the lock motorcircuit by de-energizing the lock relay.• The lock motor stops and lock switch 1 is heldclosed by the cam thru the clean cycle.• LOCKED DOOR stops flashing and remainsilluminated in the display.• ON illuminates in the display.3. During the clean cycle:• The broil relay closes and the broil burner beginsto heat. The broil burner operates alone duringthe first 30 minutes of the clean cycle, followedby the bake burner alone during the remainingtime.• As the clean cycle progresses and thetemperature of the oven control area rises, thecooling fans are activated.• A normally closed thermal switch is mountedon a bracket in front of the cooling fan. Thisswitch is in the lock switch circuit and opensthe lock switch circuit in the event of an over-temperature condition in the control area(caused by a stalled fan, fan switch failure,or similar condition). An F2 (overtemperature)failure code will appear on the control if thisswitch opens while the oven is above 715°F(379°C) for double ovens or 770°F (410°C) forsingle ovens. With the oven between 400°F(204°C) to 600°F (315°C), the clean cycle willbe canceled by the opening of the switch andthe control will revert back to the time-of-daymode. Below 400°F (204°C), the lock motor willrevolve continuously, and the words LOCKEDDOOR will flash on the control until the circuit isestablished.Motorized Door Lock Circuit InformationThere are two circuits that control the door lock.These are the lock motor circuit and the lock switchcircuit.The lock motor circuit applies voltage (120 VAC)to the lock motor. This circuit is from L1 thru thedoor switch, lock relay, and lock motor to neutral.For this circuit to be complete, the lock relay mustbe energized by the control and the door must beclosed. An open oven door results in LOCK DOORflashing in the display after the control has beenprogrammed for the clean cycle and START hasbeen pressed.The lock switch circuit tells the control if the lockmotor is in the unlocked or locked position orsomewhere in between. There are two lock switchesmounted to and operated by the lock motor.The lock switch circuit runs from the control, thru 1of the lock switches (switch 2 for unlocked or switch1 for locked), and back to the control. If neitherswitch is closed, and the oven temperature is below715°F (379°C) for double ovens or 770°F (410°C) forsingle ovens, the control will energize the lock motorcircuit until the correct switch closes to completethe circuit. If the circuit to the correct switch isopen, the lock motor will run continuously with theoven below 715°F (379°C) for double ovens or 770°F(410°C) for single ovens.Clean Cycle and Lock Sequence1. Program the clean cycle:• Press the SELF CLEAN pad. Four hours (4:00)appears on the time display. (Cleaning time canbe changed from the 4-hour starting point bypressing the SELF CLEAN pad a second time.)• After START has been pressed, ON illuminates toindicate the cycle has begun.2. Locking the door:• After programming the clean cycle and pressingthe START pad, the control energizes the lockrelay. Voltage (120 VAC) is applied to the lockmotor circuit. The oven door must be closedbefore the lock motor can run. LOCK DOOR willflash and the control will beep until the door isclosed.• The lock motor turns a cam mounted to themotor shaft.• LOCKED DOOR flashes on and off in the displaywhile the lock motor is in motion.
