Why Is My Heated Blanket Not Working: Troubleshooting Common Issues

Nothing is quite as frustrating as finding out your heated blanket isn’t working just when you need it most. Whether it fails to turn on, doesn’t get warm, or sporadically stops working, there are several potential causes and solutions. In this article, we’ll explore why your heated blanket may be malfunctioning and how you can fix it.

Why Does My Heated Blanket Not Work?

When your heated blanket stops functioning correctly, it can be due to a variety of reasons ranging from simple fixes to more complex electrical issues.

Understanding these reasons is key to troubleshooting and potentially resolving the problem without needing a replacement. Here’s a detailed look at why your heated blanket may not be working:

Faulty Wiring

• Internal Wiring: Over time, the internal wiring that heats the blanket can become damaged, especially if the blanket is frequently folded or rolled tightly. This can cause breaks in the wires, preventing them from heating properly.
• Inspection and Handling: Regularly inspect your blanket for any signs of wear or damage. Be gentle when folding or storing the blanket to avoid bending the wires excessively.

Control Unit Issues

• Defective Controls: The control unit regulates the temperature and settings of the blanket. If this unit is malfunctioning, it may fail to turn on or adjust the heat settings.
• Troubleshooting Tip: Try resetting the control unit by unplugging it for a few minutes, then plug it back in. Also, check for any loose connections or signs of damage on the unit itself.

Overheating Safety Features

• Automatic Shutoff: Most modern heated blankets are equipped with safety features that automatically shut off the power to prevent overheating. If your blanket isn’t working, it may have activated this safety feature due to being folded or covered by other heavy bedding.
• Solution: Ensure the blanket is spread out evenly and not covered by other items when in use. Reset the blanket by disconnecting and reconnecting it to the power source.

Why Is My Heated Blanket Not Turning On?

If your heated blanket won’t turn on at all, here are some steps to diagnose and potentially fix the issue:

Power Supply Check

• Electrical Outlets: First, ensure that the issue isn’t with the power outlet. Plug a different device into the same outlet to see if it receives power.
• Power Cords and Plugs: Check the power cord and plug of the blanket for any signs of damage or wear. Frayed cords or cracked plugs can prevent the blanket from powering up.

Electronic Controller Problems

• Dead Batteries in Remote: If your blanket uses a remote control, check if the batteries need replacing.
• Controller Malfunctions: Controllers can fail due to electronic malfunctions or physical damage. Inspect the controller for any visible signs of damage. If the controller displays an error code, refer to the manufacturer’s manual for specific troubleshooting based on the code.

Resetting the Blanket

• Complete Reset: Sometimes, completely resetting the blanket can resolve electronic glitches. Unplug the blanket, wait a couple of minutes, and then plug it back in. Check if this action helps the blanket to start working again.

Manufacturer’s Instructions

• Consult the Manual: Always check the user manual for specific troubleshooting tips related to your model. Manufacturers often provide detailed instructions for resolving common issues.

Why Does My Heated Blanket Not Get Hot Anymore?

If your heated blanket has stopped getting hot, there are several potential reasons behind this issue. Understanding and addressing these can help you restore its functionality or decide if it’s time for a replacement. Here’s a deeper dive into the common causes and solutions for a heated blanket that no longer heats up:

Worn Out or Damaged Heating Elements

• Breakage in Heating Wires: The most common cause for a heated blanket not getting hot is damage to the internal heating wires. These wires can break or fray over time due to folding, washing, or wear and tear, disrupting the electrical circuit needed to produce heat.
• Inspection and Care: Regularly inspect your blanket for any signs of damage or unusual wear. Avoid excessively folding the blanket tightly or placing heavy objects on it, as this can cause the wires to break.

Electrical Connection Issues

• Loose Connections: If the connections between the power cord, the controller, and the blanket are loose, the electricity required to heat the blanket might not be adequately flowing.
• Solution: Check all the connections to ensure they are snug and secure. Unplug and replug the connections, and look for any signs of damage or wear on the cords and connectors.

Malfunctioning Thermostat or Control Unit

• Faulty Thermostat: The thermostat within the blanket or the control unit may malfunction, failing to detect the correct temperature or improperly regulating the heat output.
• Testing and Replacement: If you suspect the thermostat or control unit is the problem, try adjusting the settings to see if there’s any change in heat output. If not, the control unit may need to be replaced.

Accumulated Dirt or Debris

• Impact of Dirt: Over time, dirt, dust, and other debris can accumulate on the heating elements of the blanket, acting as an insulator and preventing the blanket from heating properly.
• Cleaning: Follow the manufacturer’s instructions for cleaning the blanket. Some blankets can be machine washed, while others may require spot cleaning or professional cleaning to avoid damaging the internal components.

Overheating Safety Features Activated

• Automatic Safety Shutoff: Many modern heated blankets come with an auto-shutoff feature designed to prevent overheating. If this feature is triggered, it may prevent the blanket from heating up again until the system is reset or the issue causing overheating is resolved.
• Reset Procedure: Try unplugging the blanket for a few minutes and then plugging it back in to reset the safety mechanism. Ensure the blanket is spread evenly without any folds or bunches before turning it back on.

Advanced Wear and Tear

• Age of the Blanket: Like any electronic device, heated blankets have a lifespan. Over time, the components age and may not work as efficiently, or they can fail altogether.
• Consider Replacement: If your blanket is old and the issues persist despite troubleshooting, it might be time to consider purchasing a new one. Look for newer models with improved safety and heating technology.

I once had a heated blanket that wouldn’t heat up, and after some investigating, I realized the plug was slightly pulled out from the wall socket due to rearranging my room furniture. Once I secured the plug, my beloved heated blanket worked just like new, pairing perfectly with my Puffy Lux Mattress for a snug sleep.

Effective Fixes for a Non-Heating Heated Blanket

When your heated blanket stops heating, implementing effective fixes can sometimes restore its functionality. Here’s how you can troubleshoot and potentially fix the issue:

Check and Replace Wiring

• Inspection and Repair: Carefully inspect the wires within the blanket for any signs of breakage or wear. If accessible and if you have the technical know-how, consider replacing damaged wires or connectors. However, for safety reasons, this is often best left to professionals or handled through manufacturer support.

Reset the Electrical System

• Full Reset: Unplug the blanket and leave it disconnected for an extended period (at least 15 minutes). This can help reset the internal electronics and potentially resolve minor electronic glitches that may prevent the blanket from heating.

Conclusion

A non-working heated blanket can be a source of discomfort, especially in the colder months. By understanding the common issues outlined above and using the suggested troubleshooting methods, you can potentially fix your heated blanket and continue to enjoy the comfort it provides.
