Troubleshooting Guide: Sunbeam Heated Blanket Blinking Lights


Common Causes Of Blinking Lights

Understanding the reasons behind blinking lights on your sunbeam heated blanket

Have you ever curled up in bed with your sunbeam heated blanket only to be greeted by blinking lights? Don’t panic as this is a common issue faced by many users. Blinking lights signify a problem with the blanket’s heating mechanism, and several underlying reasons could cause it.

Here are some of the most common causes of blinking lights on your sunbeam heated blanket.

Faulty Connections

A faulty connection could be the primary reason for blinking lights on your sunbeam heated blanket. The electric cord that connects to the blanket needs to be attached firmly to the wall and the control module. If the connection is loose or insufficient, it can lead to irregular power supply, resulting in blinking lights.

  • Check the connection of the blanket cord to the control module and wall outlet.
  • Inspect the cord for any wear and tear or cuts that could be affecting the wiring.
  • Make sure that the plug is firmly attached and that you have a proper power supply.

Blown Fuse

A blown fuse is another common reason for blinking lights on your sunbeam heated blanket. When the fuse of the blanket is blown, there is an incomplete circuit which causes the blanket to turn off. If the blanket overheats or there is an electrical surge, it causes the fuse to blow and the blanket to stop working.

  • Check the control module for a blown fuse.
  • Replace the fuse with a new one of the same amps.
  • Check the manufacturer’s instructions that came with the blanket to ensure you are using the correct fuse.

Control Module Malfunctioning

Your sunbeam heated blanket’s controller is responsible for regulating the blanket’s temperature, and if it stops working, the blanket will start blinking. A dysfunctional control module could cause the blanket to heat up or switch off at irregular intervals, resulting in blinking lights.

  • Check the control module for any physical damage or malfunctioning.
  • Unplug the blanket, re-attach the control module, and plug it back in.
  • Check the connection to the blanket and make sure it is firmly attached.

Blanket Overheating

Finally, an overheated blanket is another reason that causes the blanket to blink. Overheating usually happens when you have the highest setting on the controller, and the blanket gets too hot, causing the sensor to trigger and shut down the heating mechanism.

This can cause the controller to blink, and the blanket will stop heating.

  • Ensure you use your blanket per the manufacturer’s instructions.
  • Avoid using the highest temperature setting for too long.
  • Allow your blanket to cool down before using it again.

Several reasons cause the blinking lights on your sunbeam heated blanket, but most of them are fixable. With a little troubleshooting, patience and following manufacturer’s instructions, your sunbeam heated blanket could serve you for many more cozy winter nights to come.

Steps To Troubleshoot Blinking Lights

Are you dealing with a sunbeam heated blanket that’s blinking and not functioning properly? Don’t panic. Here is a step-by-step guide to examine and troubleshoot your sunbeam heated blanket.

Step 1: Disconnect The Blanket

The first thing to do is to disconnect the heated blanket from the power source. Unplug it from the wall socket and check that the control is properly detached from the blanket. Wait for a few minutes before proceeding with the next step.

Step 2: Check Connections

Check the connections between the controller and the blanket. If the connection is loose, secure it properly. Ensure that the controller is connected to the blanket’s correct port and that the controller’s led light is on.

Step 3: Fuse Inspection

If the blanket is still not working, check the fuse in the plug. If it is burnt out, replace it with a new one of the same rating.

Step 4: Control Module Examination

Inspect the control module for any damage. Check if the pins inside the connector are bent or broken. If damaged, replace the control module.

Step 5: Examine For Overheating

If the blanket is overheating or has been exposed to moisture, an automatic safety shut-off feature may have been activated. Wait for the blanket to cool down and dry before turning it back on.

Step 6: Blanket Inspection

Inspect the blanket itself for any damage or wear and tear. Make sure the wiring is not broken or damaged. If you find any damage, do not use the blanket and replace it instead.

Now that you’ve examined the blanket step by step, you should be able to fix the blinking issue. However, if the problem persists, you may need to seek professional help. Stay warm and cozy with your sunbeam heated blanket!
