TEST PROCEDURES

PROCEDURE

LETTER

COMPONENT TEST

1. Disconnect the power supply cord, and then remove outer case.
2. Open the door and block it open.
3. Discharge high voltage capacitor.
4. Disconnect the leads to the primary of the power transformer.
5. Ensure that these leads remain isolated from other components and oven chassis by using insulation

tape.

6. After that procedure, re-connect the power supply cord.
7. Remove the outer case and check voltage between Pin Nos. 7 and 9 of the 9 pin connector (A) on

the control unit with an A.C. voltmeter. The meter should indicate 120 volts, if not check oven circuit.

Shut-off, Cook and Heater Relays Test

These relays are operated by D.C. voltage
Check voltage at the relay coil with a D.C. voltmeter during the microwave cooking operation or
convection cooking condition.
DC

. voltage indicated ............... Defective relay.

DC. voltage not indicated ........... Check diode which is connected to the relay coil. If diode is good,

control unit is defective.

RELAY TEST

WARNING : The oven should be fully assembled before following procedure.
(1) Place one cup of water in the center of the turntable tray in the oven cavity.
(2) Close the door, touch the Compu Defrost pad twice and touch the number pad 5. And then touch the

start pad.

(3) The oven is in Compu Defrost cooking condition.
(4) The oven will operate as follows

COMPU DEFROST TEST

To protect the electronic circuits, this model is provided with a fine foil pattern added to the primary on
the PWB, this foil pattern acts as a fuse.
1. Foil pattern check and repairs.

1) Disconnect the power supply cord, and then remove outer case.
2) Open the door and block it open.
