TEST PROCEDURES

PROCEDURE

LETTER

COMPONENT TEST

1.Foil pattern check and repairs.

1)Disconnect the power supply cord.

2)Open the door and block it open.

3)To discharge high voltage capacitor, wait for 60 seconds.

4)Remove the control unit, referring to the procedure of " CONTROL PANEL ASSEMBLY, CONTROL UNIT AND KEY UNIT REMOVAL ".

5)Follow the troubleshooting guide given below for repair.

STEPS

OCCURRENCE

CAUSE OR CORRECTION

1

Only pattern at "a" is broken.

*Insert jumper wire J1 and solder.

 

 

 

2

Pattern at "a" and "b" are broken.

*Insert the coil RCILF2003YAZZ between "c" and "d".

 

 

 

6)Make a visual inspection of the varistor. Check for burned damage and examine the transformer with a tester for the presence of layer short-circuit (check the

primary coil resistance which is approximately 780Ω ± 10%). If any abnormal condition is detected, replace the defective parts.

7)Reconnect all leads removed from components during testing.

8)Re-install the control unit to the control panel and re-install the control panel to the oven.

9)Reconnect the power supply cord.

10)Run the oven and check all functions.

2.Follow the troubleshooting guide given below, if indicator does not light up after above check and repairs are finished.

1)Disconnect the power supply cord, and then remove outer case. Refer to procedure of " HOOD EXHAUST LOUVER REMOVAL ", " REMOVAL OF OVEN FROM WALL " and " OUTER CASE REMOVAL ".

2)Open the door and block it open.

3)To discharge high voltage capacitor, wait for 60 seconds.

4)Remove the hood intake duct R.

5)Disconnect the leads to the primary of the power transformer.

6)Ensure that these leads remain isolated from other components and oven chassis by using insulation tape.

7)After that procedure, re-connect the power supply cord.

8)Follow the troubleshooting guide given below for repair.
