Samsung Microwave Touchpad Not Working

A malfunctioning touchpad on your Samsung microwave can be frustrating and disrupt your daily routine. When the touchpad is unresponsive, it can be challenging to set cooking times, select power levels, or perform any other functions. In this guide, we will walk you through the steps to troubleshoot and potentially resolve the issue of a non-working touchpad on your Samsung microwave.

1. Check for Basic Issues


a. Power Supply: Ensure that the microwave is properly plugged in and receiving power. Sometimes, a loose or unplugged power cord can cause the touchpad to become unresponsive.

b. Circuit Breaker: Verify that the circuit breaker or fuse for the microwave’s electrical outlet hasn’t tripped or blown. If it has, reset the breaker or replace the fuse.

c. Child Lock: Some microwaves have a child lock feature that can disable the touchpad. Refer to your user manual to learn how to disable the child lock if it’s enabled.

2. Clean the Touchpad

Accumulated dirt, grease, or food particles can interfere with the touchpad’s functionality. Cleaning the touchpad is a straightforward step that may solve the problem:

a. Turn Off the Microwave: Ensure the microwave is unplugged or turned off at the circuit breaker.

b. Clean with a Soft Cloth: Use a soft, slightly damp cloth to gently clean the touchpad. Avoid using abrasive materials or excessive moisture.

c. Allow to Dry: Ensure the touchpad is completely dry before plugging the microwave back in or turning it on.

3. Conduct a Soft Reset

Sometimes, a soft reset can resolve issues related to the touchpad:

a. Unplug the Microwave: Disconnect the microwave from the power source by unplugging it or turning off the circuit breaker.

b. Wait for a Few Minutes: Leave the microwave unplugged for at least five minutes to allow any residual power to dissipate.

c. Plug It Back In: Reconnect the microwave to the power source and turn it on. Check if the touchpad is now responsive.

4. Test the Microwave in a Different Outlet

It’s possible that the outlet where your microwave is currently plugged in is faulty. To rule out this possibility:

a. Find Another Outlet: Locate a different electrical outlet in your kitchen or home.

b. Plug In the Microwave: Connect the microwave to the new outlet and see if the touchpad works. If it does, the original outlet might have a problem.

5. Check for Error Codes

Some Samsung microwaves display error codes on the control panel. These codes can provide valuable information about the issue:

a. Refer to the Manual: Consult your microwave’s user manual to decipher any error codes displayed on the screen.

b. Contact Samsung Support: If you cannot find a solution in the manual, contact Samsung’s customer support for further assistance. They can guide you based on the specific error code.

6. Professional Repair

If none of the above steps resolve the touchpad issue, it’s possible that there’s a more complex problem with the microwave’s control panel or internal components. In such cases:

a. Warranty: If your microwave is still under warranty, contact Samsung’s customer support to arrange for warranty service or repair.

b. Out of Warranty: If the warranty has expired, consider contacting a professional appliance repair service or Samsung’s authorized service center for a diagnostic assessment and repair estimate.

7. Conduct a Hard Reset

A hard reset is a more comprehensive method to reset the microwave to its factory settings. This can sometimes resolve software-related issues affecting the touchpad:

a. Unplug the Microwave: Disconnect the microwave from the power source.

b. Wait for an Extended Period: Leave the microwave unplugged for at least 30 minutes. This extended period allows any residual electrical charges to dissipate.

c. Plug It Back In: Reconnect the microwave to the power source and turn it on. This hard reset may reset the microwave’s internal software and resolve touchpad problems.

8. Update or Reinstall Firmware (Advanced)

In some cases, a malfunctioning touchpad could be related to outdated or corrupted firmware. However, this step is more advanced and should only be attempted if you are comfortable with electronics and have the necessary tools:

a. Check for Firmware Updates: Visit Samsung’s official website and search for your microwave’s model. If there are available firmware updates, follow the instructions provided to update the microwave’s software.

b. Contact Samsung Support: If the firmware update doesn’t resolve the issue, contact Samsung’s customer support or technical support for guidance on reinstalling the firmware or troubleshooting further.

9. Inspect the Touchpad Circuitry (Advanced)

If you have experience with electronics and are comfortable opening up your microwave, you can inspect the touchpad circuitry for loose connections, damage, or corrosion:

a. Unplug the Microwave: Disconnect the microwave from the power source and ensure it is completely powered off.

b. Remove the Control Panel: Carefully open the microwave’s control panel by removing screws or clips. Refer to your user manual for guidance on safely disassembling your specific model.

c. Inspect the Connections: Examine the touchpad’s ribbon cable and the connections on the control board. Ensure that all connections are secure and free from damage or corrosion. Re-seat any loose connectors.

d. Check for Physical Damage: Inspect the touchpad itself for physical damage, such as cracks or wear. If you find any damage, it may need to be replaced.

e. Reassemble and Test: After inspecting and potentially reseating or replacing components, carefully reassemble the microwave, and test the touchpad to see if it’s responsive.

10. Seek Professional Repair

If none of the above steps yield positive results, it’s advisable to seek the assistance of a professional appliance repair technician or contact Samsung’s authorized service center. They have the expertise and specialized equipment to diagnose and repair more complex issues with the touchpad or control panel.
