Setup Instructions

- Position the Blanket: Lay the electric blanket flat on your bed, ensuring it is spread out evenly without any folds or bunches. The connector for the controller should be positioned at the foot end of the bed.
- Connect the Controller(s): For King size blankets, there are two controllers. Firmly plug each controller cord into the corresponding connector on the blanket. Ensure a secure connection.
- Plug into Power: Plug the power cord(s) from the controller(s) into a 120V/60Hz electrical outlet. Do not use extension cords or power strips.
- Ensure Proper Placement: Make sure the controller(s) remain uncovered during use to prevent overheating. Keep the power and controller cords loose and untwisted to avoid pinching or damage.

Care and Maintenance
Proper care ensures the longevity and performance of your Serta Electric Blanket.
Washing Instructions
The Serta Electric Blanket is machine washable. Always disconnect the controller(s) from the blanket before washing.
- Pre-soak (Optional): For best results, pre-soak the blanket for 15 minutes in cold water with a small amount of mild detergent.
- Machine Wash: Wash on a delicate or gentle cycle in cold water. Use minimal detergent. Do not use bleach.
- Rinse: Rinse thoroughly in cold water.
- Spin Cycle: Run a short spin cycle to remove excess water. Remove the blanket immediately after the spin cycle to prevent creasing.
Drying Instructions
- Tumble Dry: Tumble dry on a low or medium heat setting for no more than 5 minutes.
- Air Dry: Remove the blanket from the dryer while still slightly damp. Gently stretch the blanket to its original size and hang it over a clothesline or shower rod to finish drying. Do not use clothespins, as they can damage the internal wires.
- Do Not Iron: Never iron the electric blanket.
Storage
To prolong the life of your electric blanket, store it properly at the end of the season.
- Ensure the blanket is completely dry before storing.
- Roll the blanket loosely rather than folding it tightly. This helps prevent damage to the internal heating wires.
- Store in a cool, dry place. Do not place heavy objects on top of the stored blanket.

Troubleshooting
If you encounter issues with your Serta Electric Blanket, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Controller light is blinking. | Loose connection or internal error. | Unplug the blanket from the wall outlet. Firmly reconnect the controller cord to the blanket. Plug the power cord back into the wall outlet. If the issue persists, contact customer support. |
| Controller feels warm to the touch. | Normal operation. | This is normal. Small amounts of electricity cycle through the controller during operation, which may cause it to feel slightly warm. This is not a malfunction. |
| Blanket is not heating. | Not plugged in, loose connection, or incorrect setting. | Ensure the power cord is securely plugged into a working outlet. Check that the controller cord is firmly connected to the blanket. Verify the blanket is turned on and a heat setting is selected. |
| Blanket heats unevenly. | Blanket is folded, bunched, or not spread flat. | Ensure the blanket is spread out smoothly and evenly on the bed. Avoid folding or bunching the blanket during use. |
If these troubleshooting steps do not resolve the issue, please refer to the Warranty and Support section for further assistance.
