WARNING

ELECTRICAL SHOCK HAZARD

Disconnect power before servicing the range . Replace all panels before operating range . Failure to do so

can result in death or electrical shock .

FIGURE

TESTS MEASURE

RESULTS

Broil Heater

Measure resistance values of

heater’s terminal after taking off

harness from heater .

Terminal voltage of Broil heater :

AC 240V

Replace or repair harness

Replace or repair sub PCB

Bake Heater

Measure resistance values of

heater’s terminal after taking off

harness from heater .

Measure voltage of heater’s terminal

after making oven work by pressing

bake keypad . (Make sure that

voltage has to be measured for more

than 1 minute because heater is

supposed to on-off cycling work .)

Approx : 26 ~ 30Ω

(at the room temperature)

Terminal voltage of bake heater :

AC 240V

Replace or repair harness

Replace or repair sub PCB

Convection Heater

Measure the resistence values of

heater’s terminal after taking off

harness from heater .

Measure the voltage of heater’s

terminal after having oven worked,

by pressing convection bake keypad .

(Make sure that voltage has to be

measured for more than 1 minute

because heater is supposed to on-off

cycling work .)

Approx : 70 ~ 73Ω(at the room

temperature)

Terminal voltage of convection

heater :

AC 240V

Replace or repair harness

Replace or repair sub PCB

Drawer Heater

Measure the resistance of values of

heater, after taking off harness from

heater .

Measure the terminal voltage of

heater after making oven work by

pressing warming drawer keypad .

Approx : 22 ~ 25Ω

(at the room temperature)

Terminal voltage of Drawer

heater : AC 120V

Replace or repaire harness

Replace or repaire sub PCB
