OPERATION AND SERVICE PROCEDURES AUTOMATIC ELECTRIC RSS380 button (bake or clean) and rotating the time set control to move the digits back to "0:00". The display will then show time of day. If in self-clean the program also can be stopped by pressing the self-clean button a second time. The display will return to time of day. 1. Simulate initial power connector or power interruption by pressing the three (3) left hand buttons simultaneously. Each element of the display should momentarily light in sequence followed by a momentary four (4) zeros and then four (4) eights and two (2) arrows flashing. Ohmmeter checks across switch contacts 11 to 12 and 13 to 14 should indicate open switches (infinite or very high ohms). Ohmmeter should be on RX1 range. 2. Reset time-of-day on display (press in two (2) left buttons and turn "Time Set" knob). Push in minute timer button (far left) and program five (5) to ten (10) seconds in display. Timer switches should indicate open condition on ohmmeter. Alarm buzzer should sound at the end of the countdown. Push minute minder button to stop buzzer. 3. Connect the ohmmeter set to RX1 range across either time switch 11 to 12 or 13 to 14. Press in the "Bake" button and hold. Meter should indicate open switch (infinite or very high ohms). While holding button in, set approximately ten (10) seconds on the display. Meter needle should swing to zero (0) ohms indicating switch closed. Repeat the procedure after transferring the test leads to the other switch. Allow countdown to complete, buzzer should sound. Push button in to silence buzzer. Display should return to time of day. 4. With ohmmeter connected across one of the switches and set to RX1 range, push in the "Stop" button and program time of day plus ten (10) minutes. Meter should indicate switches are open. Push in "Bake Time" button - switches should still remain open. With "Bake Time" button held in, program five (5) minutes. Switches should still show open condition. Allow timer to countdown, oven should start (switches close) in five (5) minutes. After five (5) more minutes switches should open, display indicates time of day and buzzer sounds. Press bake button to silence buzzer. 5. Push self-clean button in. The following should take place immediately - three (3) hours (3:00) should appear in the display, the letter "C" should appear on the left side of the display, the oven-on symbol should also appear on the left and both switches should be closed. Manually, with "Time Set" control, turn the digital display down to one (1) minute. Allow the timer to countdown to 0:00 - display should return to timeof-day and the switches open. BUZZER ALARM The buzzer alarm sounds at the end of the minute-minder countdown. It also sounds at the completion of the timed bake or roasting cycle but not sound at the end of the selfclean program. The buzzer will sound for one (1) to two (2) minutes then shut off. It can be silenced manually by pressing any of the three (3) buttons on the left. Pressing the "Clean" button will also silence the alarm but then the three (3) hour clean setting in the displayed would need to be cleared manually. DISPLAY When the range is initially connected to the power source or after a power interruption, each element of the display will light momentarily in sequence then momentarily display four (4) zeros. Following this the display will flash four (4) eights along with the two (2) left most arrows to indicate the buttons to be pressed to set the time of day. Initial power connection or power interruption can be simulated by pressing in all three (3) left most buttons simultaneously. TO AVOID THE RISK OF ELECTRICAL SHOCK, PERSONAL INJURY OR DEATH DISCONNECT POWER BEFORE SERVICING, UNLESS TESTING REQUIRES IT. TIMER TESTING The electronic digital timer can be tested operationally and electrically. OPERATIONAL TEST This test procedure requires power applied (120 VAC) either in the range or with 120 VAC line cord connected to terminals 1 and 2 for bench test. An ohmmeter or continuity tester should be alternately connected across switch terminals 11 to 12 and 13 to 14. Selector switch must be in "OFF" position and latch in open position (non selfclean). NOTE: With selector switch in "OFF" position and latch in open position, the timer switch terminals are disconnected from circuit power sources which could damage the ohmmeter. RC231002 Rev. 3 NOTE: A slight "click" can be heard whenever the relay switches open or close. 68
