What You'll Learn
Check the power cord is connected to the wall outlet
If your Sunbeam electric blanket is not working properly, one of the first things you should do is check that the power cord is securely connected to the wall outlet.
To do this, first unplug the power cord from the wall outlet. Then, check that the control is tightly connected to the module in the blanket. Next, 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.
If your blanket is still not working properly after resetting, try using a multimeter to test the outlet. A multimeter is a small electronic device that can be used to measure electrical properties such as voltage, current, and resistance. You can purchase a multimeter at a home improvement store, a hardware store, or anywhere tools are sold. To test the outlet, insert one probe of the multimeter into the small outlet slot and place the other probe on the receptacle's center screw. If the multimeter does not light up, the outlet is not grounded correctly and you should conduct a polarity test.
If you do not have access to a multimeter, you can try using a cheap construction light socket. Simply undo the electric cord and connect the wires to the light socket. If the bulb lights up, then the power cord is working. Alternatively, you can turn the power on and hold the nose of a tester against the outside of the cord. If the tester beeps, the cord is working. Make sure to avoid using electrical cords that have been taped, especially if they are exposed to the elements.

Ensure the control cord is connected to the heated bedding module
If your Sunbeam electric blanket is not working, it is important to check that the control cord is connected to the heated bedding module.
First, examine the heated blanket, cord, and controller for signs of wear or damage. If you observe any issues, unplug the blanket and contact Sunbeam Consumer Care. If everything appears to be in good condition, proceed to the next steps.
To reset your electric blanket, start by unplugging the power cord from the wall outlet. Then, unplug the connector from the blanket or mattress pad. Wait for at least 15 minutes to allow the item to reset. Ensure that the control cord is securely connected to the heated bedding module by clicking the plastic clasps into place. Replug the connector to the blanket, making sure it is fully connected. Finally, replug the power cord into the wall outlet.
On a digital control, you should see flashing symbols, and the display on your control will clear. Your blanket is now reset. If resetting doesn't work, your heated blanket needs to be repaired or replaced. Contact Sunbeam via email or phone for further assistance.

Reset your blanket
If your Sunbeam electric blanket is not heating up, it may be time to reset it. Before you reset, you can verify whether or not your blanket is heating properly by performing the fold test. To do this, first, fold your blanket as if you were about to store it away. Then, locate the controls without unfolding the blanket and check that the control cord is properly connected to the connection module. If not, connect it by clicking the plastic clasps into place. Plug the power cord into an electrical outlet, turn the blanket "on" and set it to the highest setting. Wait for a few minutes (never more than 7), then place your hand between the folds to check if the blanket is heating.
If the blanket is not heating, you may need to reset it. To reset your Sunbeam electric blanket, follow these steps:
- Unplug the power cord from the wall outlet. Wait for at least 30 seconds.
- Unplug the connector from the blanket/mattress pad.
- Check that the control is tightly connected to the module in the blanket.
- Re-plug the power cord into the wall outlet.
- On a digital control, you should see flashing symbols and the display on your control will clear. Your blanket is now reset.
If your controller is flashing an "F" or "FF", this means that it needs to be reset. If you are still having issues after resetting, you can contact Sunbeam's customer support for further assistance.

Check the blanket's timer
If your Sunbeam electric blanket is not working as expected, it is worth checking the timer settings. The heated bedding includes an automatic 10-hour auto-off, and it will turn off after 10 hours of use. If you want to change this setting, you can do so in the Sunbeam Bedding App by pressing the timer icon. The timer can be set for up to 10 hours in 0.5-hour increments, or you can choose the "Stay On" option to keep the heated bedding on for 24 hours.
If you are having trouble connecting your controller to the app, first ensure that your Sunbeam App has Nearby and Location permissions enabled. These permissions are necessary for the app to find nearby devices and Wi-Fi names. If this does not work, try Manual Pairing mode, which will request a 2.4 GHz network. If you are still unable to connect, check that your Wi-Fi network name and password are correct.
If your blanket has a built-in timer, and you notice that the "hi" LED starts blinking after a few seconds of turning it on, there might be an issue with the timer. Before jumping to that conclusion, however, make sure that your blanket is securely connected to the wall outlet and that the control is switched to the "On" position.
If your blanket is not heating up at all, you can try resetting it. Unplug the power cord from the wall outlet, check that the control is tightly connected to the module in the blanket, and then replug the power cord. If you have a digital control, you should see flashing symbols, and the display on your control will clear. If resetting doesn't work, your heated bedding may need to be repaired or replaced.

Check the blanket's temperature sensor
If your Sunbeam electric blanket is malfunctioning, there are several troubleshooting steps you can take to address the issue. One common problem is a blinking "HI" LED, which could indicate that the blanket is overheating or that the sensor circuit is broken. To resolve this, unplug the blanket for 30 seconds and then plug it back in. If this simple reset doesn't work, you'll need to inspect the blanket for any signs of damage, such as frayed wires, loose connections, or general wear and tear. Pay close attention to the area where the cord meets the blanket, as this is a common site for damage.
If you don't notice any visible issues with the blanket, the problem could be related to the temperature sensor. The sensor may be malfunctioning, causing the blanket to overheat or fail to reach the desired temperature. To check the temperature sensor, you can use a multimeter to test the resistance of the sensor circuit. First, locate the temperature sensor on your Sunbeam electric blanket. It is usually located near the control panel or the power cord. Once you have located the sensor, consult your user manual to identify the specific model and type of sensor used. This information will be important for the next steps.
With the user manual in hand, you can refer to the instructions specific to your model for testing the temperature sensor. Look for any troubleshooting guidelines provided by the manufacturer. If no specific instructions are available, a general approach can be followed. Expose the temperature sensor to a known temperature, such as a bowl of ice water or a cup of hot water, and measure the resistance of the sensor circuit with the multimeter. Compare the measured resistance value with the expected value provided in the user manual or the manufacturer's specifications. A significant deviation could indicate a faulty temperature sensor.
If you suspect that the temperature sensor is faulty, it is essential to contact Sunbeam customer support for further guidance. They may recommend replacing the sensor or offer other specific solutions tailored to your model. Remember to consult the user manual and follow the safety precautions provided by the manufacturer when performing any troubleshooting procedures. Additionally, keep in mind that Sunbeam offers a 5-year limited warranty on most of their heated bedding products, so understanding your warranty terms can be beneficial for repair or replacement options.
