OVER THE RANGE 1.4 CU. FT.(JVM1460), AND APPOINTMENT SCHEDULER and 1.6 CU. FT. (JVM1660) SPACEMAKER CALENDAR A complete new redesign 1.4 and 1.6 cu. ft. Spacemaker is being introduced in the model line. The most significant change is in the control and the enlarged cavity size.
SURFACE LIGHTS Two 40-watt screw base incandescent tubular bulbs (WB36X10003 - 40T61/2/2) are located on the bottom outside of the grease filters. The bulbs are user replaceable by removing one screw and lowering access cover. The bulbs could be difficult to remove when replaced for the first time, a silicone glue is used to secure them during ship- ping.
DELAY START The DELAY START function provides a 24-hour delay start for any program or sequence of programs. Since it is a 24-hour timer, the start time can be delayed up to a maximum of 23 HOURS and 59 MINUTES. NOTE: The time-of-day clock must be set for the DELAY START./ function to work.
TURNTABLE The turntable should be left on for the best cooking results, however when a large dish must be used the turntable can be turned off and the rack used. Illustrations shown are the correct ways to use the rack and turntable. Press TURN- TABLE to turn the turntable off or on.
TIME COOKING FUNCTIONS CUSTOM COOK I & ll (TIME COOK I & ll) The Custom Cook function can be programmed for one or two time cook cycles in the same program. The two cycle feature is useful if a power level change is desired during the cooking operation.
CONVENIENCE FEATURES (TIME COOKING) REHEAT GUIDE POPCORN I - Pasta 2: 10 per serving 2 - Meats, casseroles, pizza 1:25 per serving The popcorn feature is a pre-timed function that allows 3 - Fruits and Vegetables 1: 15 per serving cooking prepackaged popcorn in bags of 1.75, to 4 - Beverages.

COOK The oven sets the cooking time and power level for a specific food category. To Use Cook: 1. Touch COOK. 2. Select food type , see guide. 3. Enter weight in ounces. 4. Touch START. NOTE: To display the food type and remaining cooking time, touch the COOK pad.
POPCORN The POPCORN feature is a pre-programmed function that uses the humidity sensor to automatically select the correct cooking time. NOTE: Use of the metal shelf with the popcorn pad is not recommended. This feature works best when the popcorn contents are in the 1.

4. Lift up on control to release hinge from mounting screw 2-1 In connection with pads (GE Models, others remove mounting screw). a) When touching the pads, a certain group of pads do CONTROL SMART BOARD (PCB) not produce a signal Note: Most connectors are positive lock, check before pulling b) When touching the pads, no pad produce a signal.
KEY PANEL The key panel has I ribbon connector on smart board. If necessary, the key panel pads can be checked by a continuity test. For ease of handling, the key panel or control should be removed and placed on a flat surface. Part of the ribbon connections are on one side and the remainder on the other side.
3. If the door is opened, and the primary interlock switch and power relay contacts fail to open, the monitor fuse blows simultaneously with closing of the monitor switch contacts. CAUTION: Before replacing a blown monitorfuse, test the primary interlock switch, door sensing switch, monitor switch andpower relay contactsfor proper operation.
MONITOR SWITCH TEST Disconnect the oven from power supply. Before performing this test, make sure that the primary interlock switch and the power relay are operating properly. The monitor switch is located between the top and bottom interlocks. The monitor switch is operated indirectly by the bottom latch pawl.
DOOR ASSEMBLY The door assembly will be available as a complete TOP HINGE BOTTOM HINGE assembly with handle. The handle will also be available as a separate part as will the rest of the door as seen in BOTTOM HINGE TOP HINGE the door breakdown.
ANTENNA To Remove the Antenna: A motor drives the antenna assembly and is located at the 1. Carefully pry down, using a very small (pocket) flat top of the cavity. This oven uses a top feed wave guide. The blade screwdriver, the push pin (fastener) located in antenna blade rests on a depression inside the antenna the antenna cover.
Checking with a high ohm scale, if the high voltage capaci- tor is normal, the meter will indicate continuity for a short time and should indicate an open circuit once the capacitor is charged. If the above is not the case, check the capacitor with an ohmmeter to see if it is shorted between either of the terminals and case.
HOOD THERMAL CUTOUT This cutout will protect the touch control from excessive heat by turning the vent fan on at low speed. If the surface units of the range are used for long periods of time heat will build up and could damage the microwave control.
SENSOR The sensor is a plug-in device located in the air exhaust duct, behind the grille on the left side. To Service: 1. Remove grille. 2. Separate retainer from receptacle and unplug sensor. GAS SENSOR TEST Microwave sensor cooking uses a special gas sensor which detects both humidity (steam) and hydrocarbons (food odors) during the cooking process.
SENSOR DETECTION TEST 1. Place 1/3 cup tap water in oven. 2. Touch VEGETABLE (jvm1660), oven starts immediately. POPCORN (jvm1650) 3. Control beeps and shuts off. 4. Touch CLEAR/OFF A) Test OK--Normal B) Test Fails--Check Sensor. (see quick test previous page) PROBE RECEPTACLE Receptacle is located on right hand side of cavity.
RUN CAPACITOR The run capacitor is located behind the control panel. The capacitor is used for more torque and electrical phasing. REMOVE SIDE PANEL TO Without the capacitor the blower might run but would ACCESS HI-VOLTAGE TRANSFORMER AND be much slower. MAGNETRON To Test the Capacitor: 1.

MAGNETRON The magnetron location is on the side of the cavity with a top waveguide. The magnetron thermal cutout will still be at- tached to the side of the mag by two screws. It is resettable. MAGNETRON ASSEMBLY TEST High voltages are present during the cook cycle, so extreme caution should be observed.
POWER PERFORMANCE TEST 1. Measure line voltage (loaded). This test is based on normal voltage variations of 105V to 130V. Low voltage will affect power and temperature rise. 2. Place WB64X0073 Beaker containing exactly one liter (1,000m 1) 59'F-75'F water in center of shelf. Record the starting water temperature with an accurate glass thermometer. 3. Set at high (power level 10) and set time for 2 minutes and 3 seconds.
SERVICING TROUBLESHOOTING GUIDE When troubleshooting the microwave oven, it is helpful to IMPORTANT: If the oven becomes inoperative because follow the Sequence of Operation in performing the of a blown monitor fuse in the monitor switch, primary checks. Many of the possible causes of trouble will require interlock relay and secondary interlock switch circuit, that a specific test be performed.
