– No commercial oven
cleaner or oven liner protective coating of any kind
should be used in or around any part of the oven.
– The health
of birds is extremely sensitive to the fumes released
during an oven self-clean cycle. Fumes may be
harmful or fatal to birds. Move birds to a well-ventilated
room.
– The oven
vent is located above the left-rear surface unit. This
area could become hot during oven use. Never block
this vent and never place plastic or heat-sensitive
items near the vent.
– Always place oven
racks in the desired location while the oven is cool. If
a rack must be moved while the oven is hot, do not
let the pot holder contact a hot oven burner or oven
bottom.

If the control knob is left in the Lite position, the electronic ignition system will continue to click and spark. It is not
recommended to operate any surface burner in the Lite position, since all electronic igniters spark at the same time.

The 5,000 BTU burner provides precise cook easy assembly and accurate
and dependable operation. The different burner sizes ensure you have
cooking performance for delicate foods and foods that require low heat for
long cooking times. The 5,000 BTU burner allows the LO setting to be used

The 9,500 BTU center oval burner can also be used for large pots and pans, but is designed to
be used with the center burner grate and/or the center griddle accessory. The oval burner also
spreads out the heat more evenly over the large center cooking area.
Each surface burner has a control knob with settings from HI to LO. They also have a Lite setThe electronic ignition system sparks when the control knob is in the Lite position.

worked
DIAGNOSIS
REMEDY
Measure an input voltage. (120V)
Measure an input voltage of power cord
housing.
Check circuit breaker.
Make sure that the state of wire is
connected with power cord housing.
Measure voltage of connector (CN101)
on Main PCB L1~N : 120V
Check the harness is inserted into the
relay on sub PCB
Replace or repair harness.
Replace Main PCB.
Make sure that the relay on Main PCB
is properly worked.
Replace or repair harness.
Replace or repair Main PCB.
Measure voltage regulator(IC102) on
Main PCB.
- IC102 : 7812A(DC 12V)
Measure voltage regulator(IC103) on
Main PCB.
- IC103 : 7805A(DC 5V)
Open and close the door again.
(Beeping sounds indicate that the food
is ready to be removed from the oven
after cooking is complete.)
Check whether valve of gas line is
opened
Make sure that valve is opened.
Check whether ignition spark is
generated from the electrode
Make sure that terminal of electrode is
connected to the spark module
Replace the electrode (in case of
broken electrode or cut-off wire)
Replace the spark module.
Check whether harness is connected
to Broil, Bake and convection heater
(Disconnected or Loosen)
Repair and replace harness.
Measure the resistance of both ends of
housing at hot surface ignitor
)
Repair the hot surface ignitor
Measure the voltage of Safety valve
(This should be corrected to 3.3/3.6
amps VAC.)
Repair the safety valve
Make sure that heater relay and pattern
on main PCB.
Replace or repair relay.
Replace or repair Main PCB.
Check whether temperature is risen
over
F
within 10 minutes at
room temperature.
If relay on Main PCB has a short circuit,
replace it.
Check whether harness is
misconnected or has a short circuit.
Replace the harness.
Make sure that keypad cable on
Display PCB is in normal state.
Replace the keypad in case that it is
loosen or disconnected.
Make sure connector (CN201) on
Display PCB or PCB pattern.
Replace or repair the keypad in case
cable is loosen or disconnected.

SYMPTOM
DIAGNOSIS
REMEDY
Check a relay(RY506) and a
terminal(T508) at warming drawer
Replace the terminal(T508) or relay
(RY506).
Replace a Main PCB.
Measure whether resistance of
warming drawer heater is in normal
extent or not.
Replace a warming drawer heater.
Check the oven lamp’s relay and
connector (CN501).
Replace or repair if the harness is
loosen or disconnected.
Replace oven relay(RY509).
Replace Main PCB.
Measure the resistance of both ends of
lamp terminal.
Replace lamp if it is disconnected.

Smell or smoke is
occurred during the
This is in normal state.
Smell or smoke from the burning dirt
in the oven might be generated at the
LED display is a little
dim or dark, so it
makes uncomfortable
to see.
LED display is inferior.
Replace the Display PCB.
There is no buzzer
beep sound while
keypad is being
touched.
Check the state of buzzer on main
PCB and whether PCB pattern has a
short circuit or has been open.
Replace or repair Display PCB.
Check the cap of regulator.
Remove the cap of regulator and mount
it again upside down.
Replace the regulator
Check the injector nozzle.
Replace the NG injector nozzle to LP
injector nozzle.
(Basically LN injector nozzles are
mounted at production line)
Check air shutter of the broil / bake
burner.
Make the air shutter fully opened.
(Basically opening of air shutter is
applied for LN gas at production line)
Check whether Convection fan relay on
main PCB and connector(CN501) is in
normal.
Replace or repair Relay.
Replace or repair connector.
Make sure whether harness between
Connector on Main PCB and Connector
(CN501) on Main PCB is connected in
normal.
Replace or repair harness.
Replace or repair connector.
Replace Main PCB.
