[15] O: PROCEDURES TO BE TAKEN WHEN THE FUSE ON THE PRINTED WIRING BOARD
(PWB) IS OPEN.
To protect the electronic circuits, this model is provided with a fuse added to the primary on the PWB.
1. Fuse check and repairs.
1) Disconnect the power supply cord.
2) Remove the covers.
3) Open the door and block it open.
4) Discharge high voltage capacitor.
5) If the Fuse is blown, replace power unit.
6) Make a visual inspection of the varistor. Check for burned damage. If the varistor has been burned, replace the power unit.
7) Examine the touch control transformer with a tester for the presence of layer short-circuit (check the primary coil resistanc e which is approximately
110 Ω± 10%). If any abnormal condition is detected, replace the power unit.
8) Reconnect all leads removed from components during testing.
9) Re-install the covers.
10)Reconnect the power supply cord after the covers are installed.
11)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.
2) Remove the covers.
3) Open the door and block it open.
4) Discharge high voltage capacitor.
5) Disconnect the leads to the primary of the power transformer.
6) Ensure that these leads remain isolated from ot her 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.
9) Disconnect the power supply cord, and then remove the covers.
10)Open the door and block it open.
11)Discharge high voltage capacitor.
12)Reconnect all leads removed from components during testing.
13)Re-install the covers.
14)Reconnect the power supply cord after the covers are installed.
15)Run the oven and check all functions.
[16] P: HUMIDITY SENSOR TEST
Checking the initial sensor cooking condition
WARNING: The oven should be fully assembled before following procedure.
1) The oven should be plugged in at least two minutes before sensor cooking.
2) Room temperature should not exceed 35 ° C.
3) The unit should not be installed in any area where heat and st eam are generated. The unit should not be installed, for example, next to a conven-
tional surface unit. Refer to the “INSTALLATION Instructions”.
4) Exhaust vents are provided on the back of the unit for proper cooling and air flow in the cavity. To permit adequate ventilation, be sure to install so
as not to block these vents. There should be some space for air circulation.
5) Be sure the exterior of the cooking container and the interior of the oven are dry. Wipe off any moisture with a dry cloth or paper towel.
STEPS OCCURRENCE CAUSE OR CORRECTION
1
The rated AC voltage is not present between Pin No. 1 of the 3-pin con-
nector (A) and the oven side terminal of the relay RY1
Check supply voltage and oven power cord.
2
The rated AC voltage is present at primary side of touch control trans-
former.
Touch control transformer or secondary circuit defective.
Check and replace the power unit.
