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-prong" AC cord. 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 specified 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.
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 field-effect transistors. Immediately before handling any semiconductor components or assemblies, drain the electrostatic charge from your body by touching a known earth ground.

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 specifications. A replacement part that does not have the same safety characteristics as the original might create shock, fire 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.

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

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

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

checked. But, if the oven turns off, the stored error codes are deleted. Press [Function + Time] button to return to 'normal display mode'.

4-1-1 Temp Sensor Error

Error Code	Gerneral Function	Solution	Page
	Cavity upper sensor open	Sensor Open ErrorIt occurs due to a defective sensor, misplaced wires, a defective PCB.	29 Page
	Cavity lower sensor open
	Cooling motor sensor open
	Steam generator sensor open
	Cavity upper sensor short	Sensor Short ErrorIt occurs due to a defective sensor, misplaced wires, a defective PCB. It may occur when the ambient temperature falls under -5°C.	30 Page
	Cavity lower sensor short
	Cooling motor sensor short
	Steam generator sensor short

4-1-2 Safety Error

Error Code	Gerneral Function		Solution	Page
	Overtime		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 fire 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.	32 Page
	Temp	Time
	~ 100°C	16 hours
	105°C ~ 240°C	8 hours
	245°C ~	4 hours
	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.	31 Page
Error Code	Gerneral Function		Solution	Page
	Divider Missing		This error occurs when the divider sensing switch senses that the divider is used at the inappropriate mode.	33 Page
	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.	35 Page
	Excess of cooking compartment's temperature		- This error occurs when the temperature of cooking compartment maintains over 320°C for more than 5 minutes.- This error occurs when a fire occurs inside cooking compartment or the temperature cannot be controlled because of sensor's failure.	38 Page
	Excess of cooking compartment's temperature		- This error occurs immediately after the temperature of cooking compartment reaches 350°C.- This error occurs when a fire occurs inside cooking compartment or the temperature cannot be controlled because of sensor's failure.	38 Page
	Cooling motor lock sensed		- This error occurs when the temperature sensor on the Main PCB senses abnormal temperature.- It occurs 30 ~ 60 minutes after the cooling motor does not operate.- It may occur when the cooling motor stops running by power off during operation of the oven, then it runs again.	34 Page
	Excess of steam generator temperature		- This error occurs when the temperature sensor in the steam generator senses abnormal temperature.	36 Page
	Water valve open sensed		- This error occurs when generator sensor can not sense the water even though water valve is opened for 30 sec.	28 Page
