Reset the blanket by unplugging and replugging the power cord
If your Sunbeam electric blanket is not heating up, you can try resetting it by unplugging and replugging the power cord. This is a simple process but could fix the issue and get your blanket working again.
First, unplug the power cord from the wall outlet. Make sure the control is tightly connected to the module in the blanket. Then, re-plug the power cord into the wall outlet. If you have a digital control, you should see flashing symbols and the display on your control will clear. Your blanket is now reset.
This method can be useful if you see a blinking red light on the controller, which indicates a short or disconnection in the wiring. Resetting your blanket can resolve this issue and get it heating up again.
If the resetting doesn't work, you may need to contact Sunbeam for further assistance or to inquire about warranty information and replacement parts.

Check the wiring for any shorts or disconnections
If your Sunbeam electric blanket is not heating up, it could be due to a short or disconnection in the wiring. This is indicated by a blinking red light on the controller.
To check for any wiring issues, start by unplugging the adapter from the blanket. Inspect the wiring for any visible signs of damage, such as exposed wires, frayed insulation, or loose connections. Ensure that all connections are secure and that there is no damage to the wiring.
If no issues are found, plug the adapter back into the blanket and test it again. If the blinking red light persists, it indicates that there is an internal wiring issue. In this case, the blanket has likely failed and will need to be replaced.
Before replacing the entire blanket, you can try resetting it. Unplug the power cord from the wall outlet and check that the control is tightly connected to the module in the blanket. Re-plug the power cord and observe if there are any flashing symbols on the digital control. If the reset is successful, the display on your control will clear, and your blanket should now function properly.

Ensure the control is tightly connected to the module in the blanket
If your Sunbeam electric blanket is not working, it is important to check that the control is tightly connected to the module in the blanket. This is because a loose connection can cause a short or disconnection in the wiring, which may prevent the blanket from heating up.
To do this, first, unplug the power cord from the wall outlet. Then, check that the control cord is properly connected to the module in the blanket. Ensure that the connection is tight and secure. Once you have done this, re-plug the power cord into the wall outlet.
If your control has a digital display, you should see flashing symbols and the display on your control will clear. Your blanket is now reset. If the reset doesn't work, your heated bedding may need to be repaired or replaced.
It is important to note that Sunbeam heated bedding products will not feel hot to the touch when laid out flat in a normal manner. This is by design, as they are meant to provide appropriate heat to help maintain your body's warmth and keep you comfortable.

Check Nearby and Location permissions in the Sunbeam App
If you are unable to pair your Sunbeam electric blanket with the Sunbeam app, you should first check that your app has the correct permissions enabled. To do this, open the Settings app on your device. From there, find and tap "Location", then "App location permissions". Find the Sunbeam app in the list of apps and ensure that Location permissions are enabled.
The Sunbeam app requires access to your location and Nearby permissions to function properly. This is because the app uses Bluetooth Low Energy (BLE) technology to connect to your blanket. BLE technology enables devices to connect wirelessly over a low-power connection, and it relies on location services to determine the proximity of nearby devices.
Your location is not tracked by the Sunbeam app, and these permissions are only used to allow the app to find and connect to your electric blanket. If you are still unable to connect your controller to the app, try the following steps:
- Ensure that your Wi-Fi network name and password are typed correctly. Note that they are case-sensitive.
- Make sure that your mobile device is connected to a 2.4 GHz Wi-Fi network, as this is the only type of network supported by the Sunbeam Bedding App.
- Try connecting in Auto-Pairing mode, found in the "Controlling Your Bedding" section of the Instruction Booklet. If this does not work, try Manual Pairing mode, which will request a 2.4 GHz network.

Contact Sunbeam to inquire about warranty information and replacement parts
If your Sunbeam electric blanket is not working as expected, you can contact Sunbeam to enquire about warranty information and replacement parts. Sunbeam offers a five-year limited warranty on most of its heated bedding products. To obtain warranty service, you can use the "Contact Us" form on the Sunbeam website or call the phone number provided. When mailing your product for repair, be prepared for the process to take about three weeks.
It is important to note that the warranty does not cover normal wear and tear, cosmetic damage that does not affect functionality, or damage caused by misuse, abuse, improper cleaning, or unauthorised alterations or repairs. Additionally, Sunbeam is not liable for defects or damage caused by Acts of God, such as fire, tornadoes, hurricanes, or floods.
Before contacting Sunbeam, you can try some basic troubleshooting steps. If your electric blanket is not heating, unplug the adapter from the blanket and plug it back in to test if that resolves the issue. You can also try resetting your heated bedding product by unplugging the power cord from the wall outlet, checking the connection between the control and the module in the blanket, and then replugging the power cord.
If your Sunbeam electric blanket is no longer covered by the warranty or if you prefer to explore other options, you may need to purchase replacement parts. In some cases, you may be able to replace the blanket itself without having to replace the adapter. You can also consider buying a new controller to see if that resolves the issue, as some problems with Sunbeam electric blankets have been attributed to the controller.
