My DualTemp™ Layer Doesn't Work

This guide can help if your DualTemp™ layer is not cooling, not heating, has weak airflow, or is not responding the way it should. We’ll walk you through the fastest steps to check your setup, clean your fan, and decide what to do next.

DualTemp™ is an optional Sleep Number® layer that heats or cools the surface of your bed.

Start here

First, click/tap the fan that matches your DualTemp™ layer system. The fan is usually on the floor near the bed and connects to the DualTemp™ layer with a hose.

• If you do not see a fan on the floor, your bed may not have a DualTemp™ layer.
• If you are not sure whether you have DualTemp™, check your purchase information or look for a DualTemp™ remote and hose connected to a fan.
• If your bed does not have DualTemp™, this article will not apply.
• If you have an older bed or are not sure which model you have, use the fan color and hose connection to choose the closest steps below.

Gray DualTemp fan

1. Check the hose, fan, and space around the bed

1. Turn the fan on High.
2. Check the full length of the hose for kinks, pinches, or tight bedding.
3. Make sure the hose is fully connected to the fan and that the connector is not cracked or broken.
4. Make sure there is at least 1 foot of open space around the fan so it can pull in room air and move it through the layer.
5. If the fan is inside furniture, move it next to the bed if there is not enough open space under the bed.

2. Clean the fan

1. Turn the fan off.
2. Wipe the outside with a clean, dry cloth.
3. Vacuum the metal mesh to remove dust buildup.
4. Turn the fan back on and check for airflow again.

3. Check airflow and temperature

1. With the fan on High, feel for airflow at the back of the fan.
2. Then feel the surface of the DualTemp™ layer.
3. If there is no airflow, the fan may need service or replacement.
4. If there is airflow but the bed is not getting warmer or cooler after about 20 minutes, check room temperature, bedding layers, and fan space. If the issue continues, contact us for help with the fan, hose, remote, or layer.

If the fan blows warm air when set to Cool, or cool air when set to Heat, turn the fan off, unplug it for 30 seconds, plug it back in, and try again. If the temperature still does not change, contact us for support.

White DualTemp fan

1. Check the hose, fan, and space around the bed

1. Turn the fan on High.
2. Check the full length of the hose for kinks, pinches, or tight bedding.
3. Make sure the hose is fully connected to the fan and not damaged.
4. Make sure there is at least 1 foot of open space around the fan.
5. If the fan is inside furniture and space is limited, move it next to the bed.

2. Clean or replace the filters

White DualTemp™ fans use filters. Clean or replace them every 6 months.

1. Remove the magnetic filter covers.
2. Remove the filters.
3. Hand wash the filters with warm, soapy water.
4. Rinse with clean water.
5. Let the filters air dry completely before reinstalling them.

3. Check airflow and temperature

1. With the fan on High, feel for airflow at the back of the fan.
2. Then feel the surface of the DualTemp™ layer.
3. If there is no airflow, the fan may need service or replacement.
4. If there is airflow but the bed is not getting warmer or cooler after about 20 minutes, check room temperature, bedding layers, and fan space. If the issue continues, contact us for help with the fan, hose, remote, or layer.

If the fan blows warm air when set to Cool, or cool air when set to Heat, turn the fan off, unplug it for 30 seconds, plug it back in, and try again. If the temperature still does not change, contact us for support.

Tips that can improve heating and cooling

Keep your room cool enough

DualTemp™ uses the air in your room. For best cooling performance, keep your room at 72°F or cooler.

Place your mattress pad correctly

Place your mattress pad under the DualTemp™ layer. A mattress pad on top of the DualTemp™ layer can block airflow and reduce heating or cooling.

Use breathable sheets

Use breathable fitted sheets. Thick fabrics, such as flannel, can reduce airflow and make cooling less noticeable.

Remote or control issues

If your DualTemp™ remote shows an error, keeps scanning, connects to the wrong fan, or will not turn on, replace the batteries first. Then unplug the fan for 30 seconds, plug it back in, and try again. Find additional troubleshooting for your DualTemp remote in our troubleshooting section.

Fan noise

Some fan sound is normal while DualTemp™ is running. If the fan sounds louder than usual, make sure it is on a flat surface, the hose is not kinked, and the vents or filters are clean.

When to contact us

• Your remote shows an error, keeps scanning, connects to the wrong fan, or does not turn on.
• Your fan has power but will not start.
• There is airflow, but the layer does not heat or cool after 20 minutes.
• One side works and the other side does not.
• You need help with a replacement power cord, hose, remote, filter, fan, or layer.
