Samsung 'Electric Range' Diagnostic Code Quick Guide
Cause
1. Disconnect power. Open the back cover. Disconnect sensor
harness from control Measure sensor resistance :1080Ω at
room temperature → If different value, replace oven sensor.
2. If there is not any problem with oven sensor, Please check
whether there is a damaged terminal or wire on harness.
3. Check resistance of oven sensor connector on main PCB
(Normal:2850Ω)
1. Disconnect power. Open the back cover. Disconnect sensor
harness from control. Measure sensor resistance :1080Ω at
the room temperature → If different value, replace oven
sensor.
2. Check the broil, bake and convection heater. Check the
resistance of each.
3. Check whether DLB of sub PCB, Broil, Bake and
Convection heater relay are being activated
4. Check wiring harnesses between main PCB on sub PCB.
5. Check the resistance of oven sensor connector on main
PCB. (Normal : 2850Ω)
1. Check if cable of keypad has been inserted into connector
of main PCB.
2. Check for short between main PCB and connector or
keypad and cable.
3. If there is not a problem with connector on main PCB and
cable of keypad, replace the main PCB.
1. Disconnect power. Open the back cover. Check wiring
harness connections between door lock switch and motor.
2. Check resistance of door lock motor ,1750~1850Ω at the
room temperature.
3. With operating door lockout, measure voltage at door lock
motor. (Normal Voltage : AC 120V)
4. Check whether door locking switch is operating properly.
