STEPS
1
Only pattern at "a" is broken.
2
Pattern at "a" and "b" are broken.
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 215ý ± 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.
STEPS
The rated AC voltage is not present between
1
the normal open terminal of the relay RY2 and
the normal open terminal of the relay RY1.
2
The rated AC voltage is present at primary
side of low voltage transformer.
9) Disconnect the power supply cord.
10) Open the door and block it open.
11) To discharge high voltage capacitor, wait for 60 seconds.
12) Reconnect all leads removed from components during testing.
13) Re-install the hood intake duct R.
14) Re-install the outer case (cabinet).
15) Reconnect the power supply cord after the outer case is installed.
16) Run the oven and check all functions.
