1. Precaution

Follow these special safety precautions.

1-1 Safety precautions ( )

1. All repairs should be done in accordance with the
procedures described in this manual. This product
complies with Federal Performance Standard 21
CFR Subchapter J(DHHS).

2. Check all grounds.

3. Do not power the OVEN from a “2
Be sure that all of the built - in protective devices are
replaced. Restore any missing protective shields.

4. When reinstalling the chassis and its assemblies,
be sure to restore all protective devices including
nonmetallic control knobs and compartment covers.

5. Make sure that there are no cabinet openings
through which people --particularly children --might
insert objects and contact dangerous voltages.

6. Service technicians should remove their watches
while repairing an OVEN.

7. Design Alteration Warning:
Use exact replacement parts only, i.e., only those
that are specied in the drawings and parts lists of
this manual. Never alter or add to the mechanical or
electrical design of the OVEN. Any design changes
or additions will void the manufacturer’s warranty.
Always unplug the unit’s AC power cord from the
AC power source before attempting to remove or
reinstall any component or assembly.

- prong” AC cord.

10. Always connect a test instrument’s ground lead to
the instrument chassis ground before connecting
the positive lead; always remove the instrument’s
ground lead last.

11. Components that are critical for safety are indi­cated in the circuit diagram by shading,
or .

12. Use replacement components that have the same
ratings, especially for flame resistance and dielec­tric strength specications. A replacement part
that does not have the same safety characteristics
as the original might create shock, re or other
hazards.

NOTE: Connect the oven to a 25 A.

When connecting the oven to a 16 A,
make sure that circuit breaker can operate.

13. Never touch any circuit wiring with your hand nor
with uninsulated tool during operation.

14. For your safety, wear gloves on your hands.

15. Remove the all water from water-tank and Steam
generator, before repairing the oven set.

8. Never defeat any of the B+ voltage interlocks. Do
not apply AC power to the unit (or any of its assem­blies) unless all solid-state heat sinks are correctly
installed.

9. Some semiconductor (“solid state”) devices are
easily damaged by static electricity. Such compo­nents are called Electrostatically Sensitive Devices
(ESDs). Examples include integrated circuits and
eld-effect transistors. Immediately before handling
any semiconductor components or assemblies,
drain the electrostatic charge from your body by
touching a known earth ground.

There are a kind of error code and two kinds of warning
codes. Possible error codes during use can be checked
before service. Press [Stand by Mode + Current time
0:00] and [Function + Time] at the same time and
hold them for 5 seconds, error codes are displayed.
Press [Function] button, the latest 5 error codes can be
checked. But, if the oven turns off, the stored error codes are deleted. Press [Function + Time] button to return to
‘normal display mode’.

Cavity upper sensor open

Cavity lower sensor open

Cooling motor sensor open

Steam generator sensor open

Cavity upper sensor short

Sensor Open Error

It occurs due to a defective sensor, misplaced
wires, a defective PCB.

Sensor Short Error
It occurs due to a defective sensor, misplaced
wires, a defective PCB. It may occur when the
ambient temperature falls under -5°C.

Overtime

Temp Time

 ~ 100°C 16 hours

105°C ~ 240°C 8 hours

245°C ~ 4 hours

This error occurs when the oven works during
CUT-OFF TIME in the same mode and at the same
temperature without any operation of an user.
This error is to prevent a risk of re and hazards in
case an user forgets to turn off the oven after use or
the oven automatically starts in an unusual way.
The oven can be used after off.

Touch Button Short This error occurs when a button is pressed and held

for over 10 seconds.
It may occur when water soaks through the inside
of the control panel or dust particles are stuck to
TOUCH PAD. In this case, remove DISPLAY PCB,
clean TOUCH PAD PCB or replace it.

Divider Missing This error occurs when the divider sensing switch

senses that the divider is used at the inappropriate
mode.

Preheating Time Out This error occurs when the set preheating time, 30

minutes, is over.
It may occur due to a heater’s open, defects of relay
contact point and wiring defects.
