Mattress Pad Not Heating
If your Sealy heated mattress pad isn’t warming, begin by confirming the power cord is firmly connected to a working electrical outlet. Double-check the controller’s power button is illuminated, indicating it’s switched ‘on’. Inspect the cord for any visible damage.
Ensure the controller display is active and not showing an error message. A reset – unplugging and replugging – can sometimes resolve minor electrical glitches. If the problem persists, do not attempt self-repair.

Always prioritize safety. Refer to the full manual for detailed precautions. Proper usage ensures a warm and comfortable sleep experience without compromising safety standards.
Can I use a heated mattress pad with any mattress?
Sealy heated mattress pads are designed for broad compatibility, fitting most standard mattresses effectively. However, optimal performance is achieved with mattresses up to 17 inches deep, ensuring a secure and consistent fit. Thicker mattresses may compromise the pad’s snugness and even heat distribution.
Always check the product specifications and your mattress depth for the best experience. A proper fit is crucial for both comfort and safety.
Is it safe to use with electric blankets?
Sealy strongly advises against using a heated mattress pad concurrently with an electric blanket. Combining these heating elements significantly increases the risk of overheating and potential fire hazards. Both devices independently regulate temperature, and layering them disrupts this crucial safety feature.
Prioritize safety by choosing one heating source for your bed. Using either the mattress pad or the electric blanket alone ensures a comfortable and secure sleep environment.
Finding Replacement Parts
Replacement controllers or cords for your Sealy heated mattress pad can be obtained through authorized Sealy retailers or directly from Sealy’s customer support. It’s crucial to use only genuine Sealy parts to maintain the product’s safety and performance standards.
When contacting support, have your model number and proof of purchase readily available. Avoid using third-party parts, as they may not be compatible and could void your warranty.
