•TECHNICAL DATA SHEET•

STANDARD TEST LOADThe standard test load is one liter (1000ml.) water with startingtemperature of 59°F ~ 75°F in a 1000ml beaker. (DO NOT USE ANY OTHER LOAD OR DISH AS RESULTSWILL VARY FROM STANDARD.)

PERFORMANCE TEST FOR MICROWAVE1. Use Glass Tray and the beaker WB64 x 0073.2. Record initial water temperature.3. Run at high power for 2:03.4. Record end water temperature.

The minimum difference between the initial and endingtemperature should be: 38°F@120V

INTERLOCKS AND MONITORThe primary, Door sensing & Monitor switches are mounted toa plastic latch board: on the right side of the cavity. Thesecondary interlock Relay (RY-2) is mounted on the smartboard. From top to bottom the switches are as follows;• Primary Interlock• Monitor• Door Sensing

HOW TO TEST PRIMARY INTERLOCK1. Disconnect power, remove Enclosure, and discharge

capacitor.2. Check continuity of switch:

• Door Closed: 0 Ω• Door Open: ∞ Ω

HOW TO TEST DOOR SENSINGMake continuity check between switch terminals.Normal reading are as follows:• Door closed : 0 Ω• Door open : ∞ Ω

MONITOR SWITCHThe bottom latch pawl pushes horizontally and actuates thelever of the monitor interlock opening the switch.

HOW TO TEST INTERLOCK SYSTEM1. Disconnect power, remove vent grille, and discharge

capacitor.2. Check 20 Amp. Fuse for continuity and proper size.

Do not use any other fuse or size except 20 Amp.3. Remove monitor switch leads to isolate switch.

Check continuity of switch with door open and door closed.• Door Closed: ∞ Ω• Door Open: 0 Ω

4. Reconnect switch wiring.5. Test Circuit Operation.

A) Connect temporary jumper across relay contacts, primaryinterlock and door sensing switches to simulate shortedswitch contacts. Locate convenient connections in circuitto be certain COM and NO terminals are used.

B) Connect ohm meter (Rx1) across the line terminals of theappliance cord. Continuity must show

• Door Closed : Some Ω• Door Open : 0 ΩC) Remove 20 Amp. Fuse – Circuit must open (∞ Ω).

If not, check wiring of monitor and interlock circuits.6. WARNING! After test, remove temporary jumper leads from

interlocks and relay, and reconnect monitor switch leads.

NOTE: Perform microwave leakage test when replacing oradjusting interlock switches or latch board.

HOW TO ADJUST INTERLOCKSThe Latch-Board is adjustable for door fit and switch operation.1. DDisconnect power, remove outer case, and discharge

capacitor.2. Loosen Latch-Board mounting screw at enlarged hole in

vertical flange.3. Adjust Latch-Board for proper switch operation, and door fit,

retighten screws.

NOTE: Perform microwave leakage test when replacing oradjusting interlock switches or brackets.

AUTOMATIC FAN FEATUREExhaust fan turns “ON” (medium speed) automatically duringsome surface unit heavy use conditions, (Can not be turned offmanually, will turn off automatically.)May stay on up to 15 mins. after range and lower oven controlsare turned off.

FAN THERMOSTATSingle pole thermostat mounted on bottom plate.Contacts close at approx. 158°F.

OVEN THERMAL CUTOUT(FLAME SENSOR)An oven thermal cutout is mounted on the Exhaust duct.Its purpose is to automatically shut off the oven in casethe cavity overheats for any reason.When replacing be sure to determine cause of failure. Thefailure sensor opens at 293°F(145°C) and is nonresetable.

HIGH VOLTAGE CAPACITORThe high voltage capacitor has an internal discharge resistor toautomatically discharge the capacitor when the oven turns“OFF”. Under normal operation, the capacitor should fullydischarge within 30 seconds.

DOORThe oven door consists of door panel with door glass, doorframe with inner glass, choke cover, latch and spring.

MICROWAVE OVEN HOODS

DOOR REMOVAL1. Disconnect power, remove the vent grille and remove glass

turntable from oven.2. Lift door up until pins clear holes of hinges.

DOOR DISASSEMBLY1. Insert flat type small screwdriver into the gap between choke

cover and lower right corner of the door frame first and thenaround the seal plate to free engaging parts of choke cover.

2. The latch can be removed by lifting up the latch until pinsclear mounting holes.

3. Disconnect spring.4. Remove the door handle with unscrewing two screws.

KEY PANEL TESTIf necessary the key panel pads can be verified by a continuitytest. For ease of handling, the key panelshould be removed and placed on a flatsurface. Check continuity betweenconnections at the end of ribbon. (Usehigh W scale.)

SMART BOARDSMART BOARD is used to serve as an electricalinterface between the control and the oven.SMART BOARD is located on the back of thecontrol panel assembly.The SMART BOARD contains the power relay,LVT, vent blower relay, surface light and heaterrelays, and other components to perform theproper switching circuits. Several disconnect plugsare also located on the SMART BOARD.

• CN1 - 7 Pin LVT, Oven Lamp, Fan Motor, Stirrer Fan Motor,Convection Motor Relay

• CN2 - 6 Pin Vent Fan, Cooktop Lamp, Damper Motor,Turntable Motor Relay

• CN3 - 4 Pin Door & Damper Connector• CN5 - 3 Pin Thermistor Connector• CN6 - 3 Pin Humidity Sensor Connector• CN7 - 11 Pin Ribbon Connector• CN8 - 2 Pin Hood TCO Connector

TO SERVICE TURNTABLE MOTOR 1. Disconnect power and remove the turntable.2. Remove the Turntable shaft.3. Remove the base plate by removing screws and

disconnect the wire leads to cook top lamp. (Figure 1)4. Disconnect the wire leads from the turntable motor

terminals.5. Remove 2 screws securing the turntable motor to the oven

cavity Assembly. (Figure 2)

SENSOR1. Disconnect sensor connector from PCB.2. Measure resistance terminal to terminal.(ohm mater scale : R X 1000)Normal : ApproximatelyBLK-RED :INFINITERED-WHT : 3.1 KohmBLK-WHT : 3.1 Kohm

NOTE* Sensor cooking conditions1. Oven should be plugged in at least 5 minutes.2. Room temperature should not exceed 95°F.3. Be sure the exterior of the cooking container and the interior

of the oven are dry.4. No sensor cooking is available immediately

after Bake, Roast and Fast Bake cooking.

REMOVING HEATERS, MAGNETRON,MAGNETRON FAN, VENTBLOWER AND POWER TRANSFORMER 1. Disconnect the wire leads to the Heater, H.V.T, Fan motor,

Magentron, MGT T.C.O, Hood thermo, Sub harness.2. Remove the screws securing the Plate Assembly.3. Remove the screws securing the Magnetron.4. Remove the nuts securing the Chamber Assembly.5. Remove the Heater.

Oven must be removed from wall.

REMOVING OVEN FROM WALL(2 PERSONS REQUIRED)Oven is hooked on metal tabs at bottom of wall mounting plateand fastened to cabinet by (3) top cabinet bolts.

CAUTION: Oven weights 77 lbs. Requires2 persons for removal

1. Disconnect Power Cord, Top exhausted models disconnectduct and remove damper assembly.

2. Remove (3) top cabinet bolts while supporting unit.3. Lift off back hooks and pull unit forward slowly providing

adequate support to prevent dropping unit during removal.

USE ONLY HEAT AND MICROWAVE RESISTIVE GLASS BOWL.
