Precaution Follow these special safety precautions. 1-1 Safety precautions ( ) 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. 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. 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. 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. 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 field-effect transistors. Immediately before handling any semiconductor components or assemblies, drain the electrostatic charge from your body by touching a known earth ground. -1- 2.

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’. 4-1-1 Temp Sensor Error Error Code Gerneral Function Solution Page Cavity upper sensor open Cavity lower sensor open Cooling motor sensor open Sensor Open Error It occurs due to a defective sensor, misplaced wires, a defective PCB. 29 Page 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. 30 Page Steam generator sensor open Cavity upper sensor short Cavity lower sensor short Cooling motor sensor short Steam generator sensor short 4-1-2 Safety Error Error Code Gerneral Function Overtime Temp Time ~ 100°C 16 hours 105°C ~ 240°C 8 hours 245°C ~ 4 hours Touch Button Short Solution Page 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 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 - 27 - 4-1-2 Safety Error (Continued) 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 compart- - This error occurs when the temperature of cooking ment’s temperature 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 compart- - This error occur immediately after the temperature ment’s 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 Exess 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 - 28 - 4-1-3 E-27,E-29, E-2b, E-71 Sensor Open Error (E-27, E-29, E-2b, E-71) YES Connect the sensor.
