Samsung Range Error Codes

Causes:

• This error code occurs when the touch control panel sensor detects the touch field for more than 8 seconds.
• Damp cloth has been placed on the control panel.
• Liquid boils over and lands on the control panel.
• More than one key has been pressed for more than 8 seconds.
• The touch PCB is defective.

Solutions:

• Check whether the cable for the keypad has been inserted into the connector on the display PCB.
• Check the keypad harness and connector.
• Check the connection between the key connector and the touch panel.
• If there is no problem with the connector on the main PCB or the cable of the keypad, replace the main PCB.

Causes:

• Door lock switch.
• Door lock motor.
• The main PCB did sense the door lock position.

Solutions:

• Disconnect power.
• Open the back cover.
• Check whether the harness has been connected to the door lock switch and motor. Resistance of Lock Motor Coil (1750 ~ 1850Ω at room temperature)

• Check the oven sensor. Resistance: 1080Ω at room temperature.

• Activate the door lock and measure the voltage at the wire connection on the door lock motor. (Normal Voltage: AC 120V)
• Check whether the door locking switch is working normally.
• Check if the harness is connected normally to the main PCB.

Causes:

• Loose communication between the Main and Display PBAs at the Control Panel
• Faulty control panel.
• Faulty main PCB

Solutions:

• Check the wire connection between the main PCB and the display PCB.
• If there is no problem with the connector on the main PCB and sub-PCB, replace the main PCB.

Causes:

• Loose connection.
• a torn or damaged harness.
• The main PCB is defective.
• The display PCB is defective.

Solutions:

• confirm that the main PCB’s power connector is firmly seated and free of moisture damage.
  • Ensure the connector clicks into place with no gaps or misalignment.
  • Inspect the connector pins for signs of corrosion, condensation, or discoloration.
  • If moisture is suspected, dry the connector thoroughly with compressed air before proceeding.
• Visually check the overlay cable to make sure that it is not burned or damaged.

Causes:

• This error code occurs when systems detect an open or shorted oven sensor. This error may be caused by defective sensors, misplaced wires, or defective PCBs.
• Oven Sensor.
• Main PCB.

Solutions:

• Disconnect power.
• Open the back cover.
• Check the sensor harness condition.
• Check whether the sensor wire is inserted into the connector correctly.
• Check the condition of the sensor harness and the connector on the main PCB. Measure the resistance of connector CNS300 on the main PCB (normal reading: 2850Ω).
• Disconnect the sensor harness.
• Check sensor resistance at room temperature:
  • Oven sensor at room temperature: 1080Ω.
  • Oven Sensor Open: over 2950Ω.
  • Oven Sensor Shorted: under 930Ω.

Causes:

• This error code occurs when systems detect an open or shorted oven sensor.
• Shorted heater element.
• Misplaced wires.
• Faulty Oven Sensor
• Faulty Broil-Bake Heater Terminal
• Faulty main PCB

Solutions:

• Check oven sensor resistance at room temperature: 1080Ω.
• Measure the resistance values of the heater’s terminal after taking off the harness from the broil.

• Turn on the Oven Bake Function, press the Start button, and check the voltage at the Oven Heater element at Normal 240 Vac.
  • If not 240 volts, replace the main PCB.

Causes:

• Shorted meat probe.
• a torn or damaged harness.
• Main PCB.

Solutions:

• With the meat probe removed, measure the DC voltage at the probe terminal; it should read approximately 5 VDC.
  • If the meter reads 0VDC, check the harness.
• Remove the connector and measure the DC voltage going to the meat probe pin, approximately 5 volts. Replace the main PCB if it is out of range.

Causes:

• Sensor opened.
• Sensor shorted.

Solutions:

• Measure the main PCB sensor resistance, NTC400, at 3900 Ω at room temperature. If open-loading or shorted, replace the main PCB.

• Instruct consumers not to use large pots on back burners on high flames for too long.

Note: C-30 is caused by excessively high temperatures around the control panel.

Causes:

• The temperature around the main PCB is too high.

Solutions:

• Locate the source causing the main PCB to overheat.
• If the main board is not being exposed to excessively high temperatures and the unit is displaying a C-31 code, replace the main PCB.

Causes:

• Divider.
• Divider sensor switch

Solutions:

• If single-cavity cooking mode >, remove the divider.
• If double-cavity cooking mode is selected, insert a divider.
• Check the divider sensor switch resistance.
  • Divider inserted: 0.2Ω.
  • Divider removed: ∞ Ω/OL
• Check if the connection between the switch and the connector is normal.
