Electric Blanket Not Working After Washing – Causes & Solutions

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

Are you one of those people who snuggle up under a cozy electric blanket to keep warm during the cold winter months? But, what if your electric blanket suddenly stops working after you wash it?

This can be quite frustrating, especially when the weather outside is cold and you’re in dire need of warmth. In this article, we will discuss the reasons why an electric blanket may stop working after washing, how to fix it, and some prevention tips to avoid this problem in the future.

Electric blankets have become increasingly popular, especially during the winter season. They are not only warm and cozy but also energy-efficient, making them a cost-effective way to keep you warm. However, just like any other electronic device, they are prone to damage.

One of the most common problems that electric blankets face is that they stop working after washing. In this article, we will help you understand the reasons behind this issue and provide you with solutions to fix it.

How do Electric Blankets Work?

Before we dive into the reasons why your electric blanket may not work after washing, it’s essential to understand how they work. Electric blankets are made up of tiny wires that are woven into the fabric. These wires are connected to a control unit that regulates the amount of heat produced by the blanket. When you turn on the electric blanket, the current flows through the wires, producing heat.

Reasons Why Electric Blanket Stops Working After Washing

There can be several reasons why your electric blanket stops working after washing. Here are some of the most common ones:

Water Damage

One of the most common reasons why electric blankets stop working after washing is water damage. Water can easily seep through the fabric and damage the wires, causing a short circuit. Even a small amount of water can cause significant damage to the wires and render the blanket useless.

Heat Sensor Failure

Electric blankets are equipped with a heat sensor that regulates the amount of heat produced by the blanket. If the heat sensor fails, it can cause the blanket to overheat, which can be dangerous. Overheating can cause the wires to melt, and in some cases, it can even cause a fire.

Electrical Shortage

An electrical shortage is another reason why electric blankets may stop working after washing. An electrical shortage occurs when there is a break in the circuit, which can be caused by a damaged wire or a faulty control unit.

Control Unit Malfunction

The control unit is responsible for regulating the amount of heat produced by the blanket. If the control unit malfunctions, it can cause the blanket to overheat or not produce any heat at all.

How to Fix an Electric Blanket That isn’t Working After Washing

If your electric blanket stops working after washing, don’t worry. In most cases, it can be fixed. Here are some steps you can take:

Check for Visible Damage

The first thing you should do is check the blanket for any visible damage. Look for any signs of wear and tear, such as frayed wires or holes in the fabric. If you notice any visible damage, it’s best not to use the blanket

Test the Blanket with a Multimeter

If there is no visible damage, you can use a multimeter to test the blanket’s wires. First, set the multimeter to the continuity mode and touch the probes to each wire. If there is a break in the circuit, the multimeter will not beep, indicating that there is a problem. If this is the case, you can use a wire stripper to remove the damaged wire and replace it with a new one.

Check the Control Unit

If the wires are not damaged, the next step is to check the control unit. Make sure that it is plugged in correctly and that the settings are correct. You can also try unplugging the control unit and plugging it back in to see if that helps. If the control unit is damaged, you may need to replace it.

What Happens If An Electric Blanket Gets Wet?

If an electric blanket gets wet, it can be dangerous and may cause electric shock or fire. The electricity in the blanket can conduct through the moisture and cause harm to the person using it.

It is important to always follow the manufacturer’s instructions for cleaning and care of the electric blanket. If the blanket is labeled as machine washable, make sure to follow the washing instructions carefully and avoid using too much water. Do not use fabric softeners or bleach, as these can damage the heating elements.

If the blanket does get wet, immediately unplug it from the power source and do not use it until it is completely dry. Do not attempt to use a wet or damp electric blanket as it can be dangerous. Hang the blanket up to air dry, or lay it flat on a dry surface, and do not use it until it is completely dry.

Overall, it is important to always take safety precautions when using an electric blanket and to follow the manufacturer’s instructions for care and cleaning.

Tips to Prevent Electric Blankets

To prevent your electric blanket from not working after washing, you should follow these tips:

  • Read the care instructions carefully before washing the blanket. Make sure to follow the instructions and not use any harsh detergents or fabric softeners.
  • Use a front-loading washer instead of a top-loader. Top-loading machines can be rough on the blanket and cause damage to the wires.
  • Do not dry the blanket in a dryer. Hang it outside or lay it flat to dry.
  • Do not fold the blanket when storing it. Instead, roll it up to avoid damaging the wires.
