Last updated on October 14th, 2023 at 11:27 pm

Heated blankets are a popular household item that provides warmth and comfort during cold winter months. They work by using electric heating elements to generate heat, which is then distributed throughout the blanket. However, if you notice that your heated blanket is flashing red, it’s important to take notice as it’s not a normal state.

We’ll explore some possible reasons why your heated blanket may be flashing red and outline troubleshooting steps to help you fix the issue.

Possible Causes of a Flashing Red Light:

There are several reasons why your heated blanket may be flashing red. Below are some of the most frequent causes:

Overheating Protection:

If the heated blanket is flashing red, one possible cause could be overheating. Heated blankets often have a safety mechanism that shuts off the blanket if it gets too hot. When this happens, the blanket will stop working and a red light will often flash to indicate the problem.

Various reasons can lead to overheating, such as:

• Leaving the blanket on for too long: If the blanket is left on for an extended period of time, it can get too hot and trigger the safety mechanism.
• Folding or bunching the blanket: If the blanket is not spread out evenly, it can create hot spots that can trigger the safety mechanism.
• Using the wrong setting: If the blanket is set to a higher temperature than recommended, it can overheat and cause the safety mechanism to activate.

To troubleshoot this issue, try the following:

1. Unplug the blanket and let it cool down for at least 30 minutes.
2. Spread the blanket out flat and make sure it is not folded or bunched up.
3. Set the blanket to the recommended temperature and try using it again.

Malfunctioning Controller:

A malfunctioning controller is another possible cause of a flashing red light on a heated blanket. The controller is the device that allows you to adjust the temperature and turn the blanket on and off. If the controller is not functioning properly, it can cause the blanket to stop working and the red light to flash.

To troubleshoot this issue, try the following:

1. Check the controller: Make sure the controller is properly connected to the blanket and the power source. If it is loose or not fully plugged in, it may cause the blanket to malfunction.
2. Reset the controller: Many controllers have a reset button that can be pressed to restore it to its default settings. Refer to the manufacturer’s instructions to locate the reset button and try resetting the controller.
3. Replace the controller: If the above steps do not solve the problem, the controller may need to be replaced.

It is important to note that a malfunctioning controller can also be a safety hazard, as it can cause the blanket to overheat or short circuit. If you suspect that the controller is the problem, do not continue to use the blanket until the issue has been resolved.

Electrical problem:

Another possible cause of a flashing red light on a heated blanket could be an electrical problem. This could be due to a faulty electrical outlet, a damaged power cord, or an issue with the wiring inside the blanket itself.

To troubleshoot this issue, try the following:

1. Check the electrical outlet: Make sure the outlet is working properly by plugging in another device and checking if it works. If it doesn’t, try resetting the circuit breaker or contacting an electrician to fix the outlet.
2. Inspect the power cord: Check the power cord for any damage, such as cuts or frayed wires. If there is visible damage, do not use the blanket.
3. Check the wiring inside the blanket: If the power cord appears to be in good condition, there may be an issue with the wiring inside the blanket. In this case, do not attempt to open the blanket yourself contact the manufacturer.

Avoiding Common Mistakes with a Heated Blanket:

Preventing a heated blanket from flashing red in the future involves taking proper care of the blanket and following some basic safety guidelines. Here are some tips on how to prevent a heated blanket from flashing red in the future:

1. Follow the manufacturer’s instructions: Before using your heated blanket, read the instructions carefully and follow them closely. This will help you avoid any common mistakes that can lead to the blanket flashing red.
2. Use a timer: To prevent overheating or electrical issues, use a timer when using your heated blanket. This will automatically turn off the blanket after a certain amount of time, which can help extend its lifespan.
3. Avoid folding or bunching up the blanket: When storing your heated blanket, make sure it’s folded neatly or rolled up loosely. Bunching up the blanket can damage the wiring and cause it to malfunction.
4. Don’t use the blanket if it’s damaged: If you notice any tears, rips, or other damage to the blanket, don’t use it. This can lead to safety hazards or further damage to the blanket.
5. Unplug the blanket when not in use: To prevent any electrical issues or fires, unplug your heated blanket when you’re not using it. This can also help save energy and lower your electricity bill.

By following these tips and taking proper care of your heated blanket, you can prevent it from flashing red in the future and enjoy many cozy nights of warmth and comfort.

Reset a Heated Blanket:

To reset a heated blanket, follow these general steps:

1. Unplug the blanket from the electrical outlet and detach it from the controller.
2. Check the manufacturer’s instructions for any specific reset instructions, as they may vary by brand and model.
3. Wait at least 5 minutes to allow the blanket to cool down completely.
4. Reconnect the controller to the blanket and plug it back into the electrical outlet.
5. Turn on the blanket and adjust it to the desired temperature setting.

If the blanket still doesn’t work properly after resetting it, check the controller for any error codes or indications of a malfunction. If the issue persists, contact the manufacturer or a qualified technician for assistance.
