How to troubleshoot an E24 error code on an electric Samsung range
Samantha Bullington / Monday November 20, 2023
If you’re seeing an E24 error code on your Samsung range, we’re here to help! This message usually indicates a problem with the oven temperature sensor that’s preventing your oven from heating properly.
If you need a replacement temperature sensor or other parts for your range, grab your model number and go to AppliancePartsPros.com to order one. Most orders arrive in just two business days.
Let’s learn more about this error code and how to resolve it so you can get your oven back up to speed.
Disclaimer: The error code information provided in this article is based on general service manuals and may not apply to your specific appliance model. While we strive to offer helpful advice for DIY appliance repairs, variations in models and configurations can lead to differences in troubleshooting steps, error codes and part replacements. For the most accurate guidance, we strongly recommend consulting the technical sheet for your specific appliance model.
What does the E24 error code mean?
On Samsung ranges, the E24 error code usually signifies a problem with the temperature sensor circuit. This temperature sensor allows the oven control board to monitor the interior temperature and adjust the heat accordingly.
When an E24 error displays, it may mean that the control board is detecting issues with the sensor that are disrupting communication. This can prevent the oven from reaching the target baking temperature.
The problem can stem from either a faulty temperature sensor itself or wiring problems between the sensor and the control board. Without accurate temperature readings, the oven can’t provide reliable heating.
Let’s check the sensor connections, wiring, and sensor resistance values.

How to fix an E24 error message
Keep safety first
As with any appliance repair, safety should always come first.
Make sure to:
- Turn off and unplug the oven before beginning work.
- Make sure the range is completely cooled off before touching any parts.
- Turn off the circuit breaker supplying power to the unit.
- Wear protective gloves when handling range parts and tools.
- Move slowly and pay close attention when working inside the oven cavity.
Tools and materials you may need
- Multimeter
- Protective gloves
- Electrical tape
- Replacement temperature sensor and/or control board

Inspect sensor connections
The first step is verifying that the temperature sensor is properly connected to the oven’s control board. Good terminal connections are needed for the control board to receive sensor input.
- Remove the back service panel to access the internal components. This is typically held on with several screws that you’ll need to remove.
- Locate the multi-wire cable that runs from the temperature sensor housing to the main control board.
- Check that the connector is firmly and fully plugged into the appropriate receptacle on the board. If the connector is loose, push it completely into the socket until it clicks and locks.
- Secure any loose wiring harness clips that may have allowed the connector to detach.

Check sensor wiring
Next, we need to inspect the condition of the wiring between the temperature sensor and the control board. The oven temperature sensor requires multiple wires to provide temperature readings. Each one needs good, intact insulation and connections.
- Closely check all wiring for signs of damage. Look for rubbing, chafing, burning, or breaks in the insulation. Wires in poor condition can cause resistance on the sensor circuit, which may lead to E24 errors.
- You might be able to repair minor insulation damage with electrical tape. For more severe damage, the wiring harness will need to be replaced.

Test the temperature sensor resistance
To make sure the temperature sensor is functioning correctly, we can check its resistance. This resistance test can help us determine if the issue is with the sensor or with the other wiring and connections:
- Unplug the sensor connector from the oven control board.
- Use a multimeter to test the resistance between the sensor wires at room temperature.
- Check the appliance service diagram for your model’s exact temperature sensor specifications. Resistance should typically read between 1000 and 1100 ohms +/- 5-10%. If the resistance is outside this range, the temperature sensor is likely defective and will need to be replaced.

Check and test the control board
If the wiring checks out and the temperature sensor is providing accurate resistance values, the oven control board itself may be faulty.
- Visually inspect the control board for signs of damage like burning, bulging capacitors, signs of a short, etc. If you find any damage, you’ll need to replace the board.
- If the board looks ok, you can test it for voltage.
- A live voltage test requires your range to be plugged in and turned on, so please don’t perform this test unless you’re comfortable using a multimeter. Take every precaution during live voltage testing since if done incorrectly, it can cause serious injury.
- Your control board should be getting 120 volts or very close to that amount. If it’s far off, you’ll need to replace the board.
- If the board needs to be replaced, only install an identical replacement part to avoid functionality issues. Take your model number to AppliancePartsPros.com to locate the correct one for your model. Control boards often need recalibration and programming when installed, so it’s important to get an exact replacement for your range model.

Reassemble and retest the oven
Once you’ve tested and/or replaced faulty components, you can retest the oven’s operation.
- Carefully reinstall any parts that were removed during the troubleshooting or replacement processes, including the back service panel.
- Restore power and reset/reprogram the control board if needed per the manufacturer’s instructions.
- Initiate an oven test bake to see if the E24 error code returns. The oven should heat to the set temperatures.
- Confirm that the electronic display, controls, and heating elements are all functioning normally before returning the range to normal use.
