Safety tips

Your safety should always be the top priority when performing any appliance repair.

• Always power off and unplug your appliance or switch off the circuit breaker before you attempt any maintenance or replacement work. This keeps you safe by eliminating any risk of electric shock. 
• If the appliance has recently been used, give it plenty of time to cool down before working on it. 
• Take your time while working to prevent accidents and personal injuries. Rushing is the enemy of precision.
• Work in a well-lit area so you can see and access appliance parts.
• Keep your workspace free of clutter and other obstacles. Keep children and pets away from the work area.
• Never work on internal parts with wet hands. Make sure the work area is completely dry.
• Check the user manual to see if there are specific installation or safety instructions related to your appliance or replacement part. 
• Be gentle when handling or removing parts. Excessive force might damage the appliance or cause personal injury.
• Wear insulated work gloves to protect your hands from sharp metal parts and debris.
• When working with wires, avoid touching any exposed wires or terminals. If you need to touch a wire, use a non-conductive tool or wear insulating gloves to prevent electrical shock.
• Always take photos or make a note of wiring terminals or other connections before disconnecting them to make reassembly easier.
• Consider wearing safety glasses and/or a dust mask when working with chemicals, dust or a large amount of debris to prevent irritation or injury.

How to troubleshoot Samsung range convection fan motor issues

Follow these steps to diagnose and fix issues with the convection fan motors, heating element, and control board on a Samsung range. Proper testing will help determine whether a component needs to be replaced or if there is a wiring or control board issue.

Step 1. Identify the issue

1. Listen for unusual noises coming from the convection fan motor.
2. Set the oven to convection bake and close the door to check if the fan is running.
3. If the fan is not moving, proceed with voltage testing.

Step 2. Test the upper convection fan motor

1. Turn off power by unplugging the range or switching off the breaker.
2. Pull the range away from the wall and remove the back panel using a Phillips head screwdriver.
3. Locate the upper convection fan motor.
4. Restore power by plugging the range back in or turning the breaker on.
5. Set the range to convection bake and close the oven door.
6. Set the multimeter to Volts AC mode.
7. Place one lead on one terminal of the fan motor.
8. Place the other lead on the other terminal without removing the wires.
9. Wait up to a minute for the board to activate the fan.
10. Check the voltage reading. It should be 120 VAC.
11. If voltage is present but the fan is not spinning, replace the motor.
12. If no voltage is detected, check the wiring for damage.
13. If the wiring is intact but no voltage is detected, replace the control board.

Step 3. Test the upper convection fan motor

NOTE: Generally, for every 1 degree in temperature difference, 2 Ohms could be added or subtracted. If the temperature in your home is cooler, resistance would be subtracted.

1. Turn off power by unplugging the range or switching off the breaker.
2. Disconnect the fan motor by removing the wire connector.
3. Set the multimeter to resistance mode (Ohms, Ω).
4. Place one lead on one terminal.
5. Place the other lead on the opposite terminal.
6. Check the resistance reading. It should be between 20-30 ohms.
7. If the reading is within range, the motor is functional.
8. If the reading is out of range, replace the motor.

Step 4. Test the lower convection fan motor

LIVE VOLTAGE WARNING: For this test, the washer needs to be plugged in and powered on. Please be very careful to protect yourself from electric shock, which has the potential to cause serious injuries. Don’t ever test live voltage if you’re uncomfortable using a multimeter.

1. Turn off power by unplugging the range or switching off the breaker.
2. Remove the back panel if it has not already been removed.
3. Locate the lower fan motor.
4. Restore power by plugging in the range or switching on the breaker.
5. Set the range to convection bake and close the oven door.
6. Set the multimeter to Volts AC mode.
7. Place one lead on one terminal of the fan motor.
8. Place the other lead on the other terminal without removing the wires.
9. Wait up to a minute for the board to activate the fan.
10. Check the voltage reading. It should be 120 VAC.
11. If voltage is present but the fan is not spinning, replace the motor.
12. If no voltage is detected, check the wiring for damage.
13. If the wiring is intact but no voltage is detected, replace the control board.

Step 5. Test the lower convection fan motor

1. Turn off power by unplugging the range or switching off the breaker.
2. Disconnect the fan motor by removing the wire connector.
3. Set the multimeter to resistance mode (Ohms, Ω).
4. Place one lead on one terminal.
5. Place the other lead on the opposite terminal.
6. Check the resistance reading. It should be between 20-30 ohms.
7. If the reading is within range, the motor is functional.
8. If the reading is out of range, replace the motor.

Step 6. Test the convection heating element

1. Turn off power by unplugging the range or switching off the breaker.
2. Remove the back panel using a Phillips head screwdriver.
3. Locate the convection heating element terminals near the lower fan.
4. Restore power by plugging in the range or switching on the breaker.
5. Set the oven to convection bake and close the door.
6. Set the multimeter to Volts AC mode.
7. Place one lead on one terminal of the heating element.
8. Place the other lead on the other terminal.
9. Wait up to a minute for the board to cycle the element on.
10. Check the voltage reading. It should be 240 VAC.
11. If voltage is present but the element is not heating, replace the element.
12. If no voltage is detected, check the wiring for damage.
13. If the wiring is intact but no voltage is detected, replace the control board.

Step 7. Test the main control board (upper fan motor)

1. Turn off power by unplugging the range or switching off the breaker.
2. Remove the back panel using a Phillips head screwdriver.
3. Locate the CN706 terminal on the control board.
4. Restore power by plugging in the range or switching on the breaker.
5. Set the oven to convection bake and close the door.
6. Set the multimeter to Volts AC mode.
7. Place one lead on CN706 pin 1 (brown wire).
8. Place the other lead on CN101 pin 3 (white wire, neutral connection).
9. Wait up to a minute for the board to cycle the fan circuit on.
10. Check the voltage reading. It should be 120 VAC.
11. If voltage is present, the motor is faulty and needs replacement.
12. If no voltage is detected, check for burned or broken wires.
13. If the wiring is intact but no voltage is detected, replace the control board.

Step 8. Test the main control board (lower fan motor)

1. Follow the same steps as for the upper fan motor.
2. Locate the CN707 terminal on the control board.
3. Place one lead on CN707 pin 3 (brown wire).
4. Place the other lead on CN101 pin 3 (white wire, neutral connection).
5. Check the voltage reading. It should be 120 VAC.
6. If voltage is present, the motor is faulty and needs replacement.
7. If no voltage is detected, check for burned or broken wires.
8. If the wiring is intact but no voltage is detected, replace the control board.

Step 9. Test the main control board (convection heating element)

1. Follow the same steps as for the fan motors.
2. Locate terminals T501 and T507 on the control board.
3. Place one lead on T501.
4. Place the other lead on T507.
5. Check the voltage reading. It should be 240 VAC.
6. If voltage is present, the heating element is faulty and needs replacement.
7. If no voltage is detected, check for burned or broken wires.
8. If the wiring is intact but no voltage is detected, replace the control board.

Step 10. Reassemble

1. Double-check all wire connections.
2. Replace any faulty components as determined by testing.
3. Reinstall the back panel and secure it with screws.
4. Restore power by plugging in the range or switching on the breaker.
5. Set the oven to convection bake and close the door.
6. Observe the fan and heating element operation to confirm that the issue is resolved.
