One thing you can be sure of when it comes to modern electric blankets is they will always send signals in case something is not in good condition. The warning can be in the form of blinking lights. In other cases, it can be flashing lights.

So, what does blinking on the electric blanket mean? Is it a major issue or could it be a minor problem? Do I need to attend to the problem immediately or can I postpone it?

In this article, we are going to address all these questions and many others that you may have with regard to why your electric blanket is blinking.

Overheating

You bought an electric blanket because you wanted to get some extra heat. However, the course of its operation, the blanket may end up generating more heat than it was supposed to. This will lead to overheating.

For most blankets, overheating will lead to the automatic shut off.  If the blanket does not switch itself off, it will start blinking to warn you of a possible heating problem. Maybe you should investigate the cause of overheating and rectify it.

Overheating could be due to letting the blanket operate at a single setting for too long: Probably the highest heat setting on the blanket. Bad handling can also lead to overheating. For example, when you keep heavy items on top of the blanket.

The best solution to the overheating electric blanket is to unplug it from the power for a while and give it time to cool. Also, check out all the components of the electric blanket to ensure that they are inn perfect condition.

Loose connection

This is another common reason for the blinking electric blanket. A loose connection between the blanket and the controller will be interpreted as a warning sign and this will subsequently lead to constant blinking or flashing.

The biggest culprit when it comes to the loose connection is the faulty wires. If the wires are not held and connected properly to their positions, then you are likely to end up with loose connections.

A faulty or damaged plug can also cause a loose connection between the electric blanket and the controller.

A loose connection can cause a bigger problem other than just the blinking light. It can easily ignite sparks which may end up causing a fire. Let’s not forget that loose connections in most electric devices can cause electric shock.

In case you suspect that the blinking blanket is due to loose connection, you disconnect it immediately from any power source. Inspect the wires and establish the actual point of the loose connection.

You should also inspect the wires connecting the blanket to the connectors on regular basis to avoid any possibility of a loose connection.

Faulty controller

The constant blinking light on your electric blanket could be due to a faulty controller. A controller is the main communication unit of the heated blanket. In case it malfunctions, you will get an immediate response, which will come in the form of blinking lights.

If you suspect that the issue is with the controller, you will have to unplug the blanket from the power and wait for further instructions from the heated blanket manufacturer.

Problem with the temperature sensors

Electric blankets come with different sensors and the most common one is the temperature sensor. A problem with the sensor can cause the electric blanket to blink.

Electric blanket blinking F2 is one of the signs that the temperature sensors is having an issue. It is a warning sign that you need to check the sensor and rectify the problem as soon as possible.

The good news is it is easy to rectify the electric blanket blinking F2.

The first solution is to unplug the blanket from the power source. This can be the battery or the wall socket. Wait for a couple of minutes, let’s say 5 minutes then switch it on again. Confirm whether the electric blanket is still blinking F2.

Another solution is to reset the controller before plugging it into the power source again.

If the two solutions yield no results, proceed to inspect the wires and the controller for any signs of physical damage.

How to reset an electric blanket

One of the solutions to a blinking heated blanket is resetting the controller. This is an ideal solution, especially if the electric blanket is blinking F2.

To reset your heated blanket, start by unplugging it from the power outlet. From there, you can inspect the buttons that are on the controller.

Do you spot the RESET button? Press and hold it down for a couple of seconds, maybe 10 seconds.

Chances are once you plug the blanket back to power after resetting the controller, the blinking light will be gone.

This solution works perfectly when you want to reset Sunbeam electric blanket.

What if the controller does not have a reset button? Well, you can go for a rather mechanical way of resetting the blanket; using a freezer. After all, the blinking could be due to an issue with the temperature sensor.

To do this, put the blanket in a tight bag and then leave it in a freezer for a couple of hours. Exposing the blanket to extreme temperatures can reset the temperature.  However, this solution can work only if you are sure that there are no other problems, for example, the wires are in good condition.

If you are not sure of the technic to use to reset the blanket, then you should consult the electric blanket manufacturer’s manual.
