Have you ever wondered why the light on your heated blanket blinks? It turns out that there are a few different reasons why this may happen. In this blog post, we will explore some of the most common causes for the light to blink on a heated blanket. From manufacturing defects to user error, there are a number of potential explanations. Read on to learn more about what may be causing your heated blanket to blink.

Heated Blanket Basics

If you have ever wondered what causes the light to blink on a heated blanket, wonder no more! Here is a brief explanation of how your heated blanket works and why the light may blink during use.

Your heated blanket has two main components: an electric heating element and a controller. The heating element is responsible for generating the heat that warms you up, while the controller regulates the flow of electricity to the heating element.

The controller is what makes your heated blanket safe to use. It contains a number of safety features that protect you from overheat or fire hazards. One of these safety features is a thermal cut-off switch.

The thermal cut-off switch is a sensitive device that monitors the temperature of the heating element. If the temperature gets too high, the switch will automatically shut off power to the heating element, preventing it from overheating.

The light on your heated blanket will blink when the thermal cut-off switch is activated. This is normal and indicates that your heated blanket is working properly. If you see the light blinking, simply turn off your heated blanket and allow it to cool down before turning it back on.

One of the most common questions we get asked is “why does the light blink on a heated blanket?” The answer to this question is actually quite simple. The light blinking on your heated blanket is simply an indication that the heating element inside the blanket is working and generating heat.

So, why does this happen? Well, when you plug in your heated blanket and turn it on, the electricity flows through the wires and heats up the coils inside the blanket. This process generates a small amount of heat, which causes the light to blink.

However, this doesn’t mean that there is something wrong with your blanket. In fact, it’s actually quite normal for the light to blink when you first turn on your heated blanket. So, if you see the light blinking on your heated blanket, don’t worry – it’s just letting you know that it’s working properly!

How to Fix a Blinking Heated Blanket

If your heated blanket is blinking, it could be caused by a number of different things. Follow these steps to troubleshoot the issue and get your blanket back to working properly.

First, check to make sure that the blanket is plugged in properly. If it is, then the next step is to check the safety switch. The safety switch is located on the side of the controller and should be in the “on” position.

If the safety switch is in the “on” position and the blanket still isn’t working, then there may be an issue with the controller. Try replacing the batteries in the controller and see if that fixes the problem.

If you’ve tried all of these things and the blanket still isn’t working, then it’s likely that there is a problem with the heating element itself. This will require you to replace the entire blanket.

Tips for Preventing a Blinking Heated Blanket

If your heated blanket is blinking, it’s likely due to one of the following reasons:

1. The blanket is overheat protected and is automatically shutting off to prevent overheating. This is usually caused by incorrect settings, so be sure to check the user manual for your specific blanket model.

2. There may be a loose connection between the power cord and the heating element. Check to make sure the connections are secure and that there are no frayed wires.

3. The heating element itself may be damaged and will need to be replaced. This is not a common problem, but if your blanket is older it may be worth checking into.

4. Finally, if none of these other factors are causing the blinking, it could simply be a sign that the battery needs to be replaced in your wireless controller. Again, consult your user manual for instructions on how to do this.

By following these tips, you can troubleshoot and fix the most common causes of a blinking heated blanket.


There are a few different reasons that the light on your heated blanket might blink. It could be because the power is turned off or on, the temperature is set too low or high, or there’s something wrong with the heating element. Whatever the reason, it’s best to consult your heated blanket’s manual for troubleshooting tips.
