TO AVOID THE RISK OF ELECTRIC SHOCK, PERSONAL INJURY OR DEATH DISCONNECT POWER BEFORE SERVICING, UNLESS TESTING REQUIRES IT.

Figure 57 - Clock/Timer P.C. Board

5.Set the Cook/Clean time for one (1) minute by press- ing the "COOK/CLEAN TIME" button ("0:00" will be displayed) and then pressing the "UP" button one time ("0:01" should be displayed). After a short delay the TB4 - TB5 contact should close (zero ohms), "AUTO" and the oven indicator symbol should appear on the left and center of the display, and the Time-of- Day will appear on the digital display. When the one

(1) minute Cook/Clean time elapses, the TB4 - TB5 contact should open (infinite ohms), an alarm will sound for approximately ten (10) seconds and the oven indicator symbol in the center of the display will turn off. "AUTO" will continue to blink ON and OFF to indicate that the Clock/Timer was programmed for a timed operation. Press the "CANCEL/CLOCK" button to turn off the blinking "AUTO" display.

6.Press the "STOP TIME" button and enter the stop time for two (2) minutes past the time of day. EX- AMPLE: Set the Time-of-Day to 12:00.

Press the "STOP TIME" button (the display will continue to show the Time-of-Day), then press the "UP" button until "12:02" is displayed.

After a short delay, contact TB4 - TB5 should close (continuity) and the display will show the Time-of-Day

along with the oven indicator in the center of the display and "AUTO" on the left of the display.

When the stop time is reached, the TB4 - TB5 contact should open (infinite ohms), the oven indicator in the center of the display turns off, and an alarm will sound approximately ten (10) seconds. "AUTO" will con- tinue to flash ON and OFF to designate that the Clock/ Timer was programmed for a timing function. Press the "CANCEL/CLOCK" button to turn off the flashing "AUTO" display.

7.Connnect the ohmmeter leads to terminals TB6 and TB7 and repeat Steps 4 - 6 to test the other K1 relay contact.

CLOCK P.C. BOARD VOLTAGE TESTS

Extreme caution must be taken when performing any live voltage tests to avoid the possibility of electrical shock or damage to the range components and/or testing equip- ment.

1.Shut off power to the range and disconnect the wire leads from the P.C. board terminals L1 (TB1) and N (TB2) to check the input voltage. Using a voltmeter
