Adjustable Bed Not Going Up? Causes and Step-by-Step Fixes

Quick answer: An adjustable bed not going up is usually a power, remote or overheating problem, not a dead motor. Check the outlet and breaker, replace the remote batteries, then unplug the base for 30 seconds to reset it. If you ran the motors a lot, Leggett & Platt says the thermal switch may have tripped: wait 30 minutes before trying again.

Leggett & Platt’s adjustable base remote guide has one of the clearest troubleshooting charts I’ve found. When I compared it with Ergomotion’s knowledge articles, the two agreed on the basics: power first, then the remote. Your base may use different buttons, so keep your own manual nearby.

First, a quick split. Does the remote light up when you press a button?

• No light at all: start with the remote. See cause 2 below.
• Remote lights, bed doesn’t move: check power, pairing and the thermal cutoff.
• Head rises, foot doesn’t (or the other way round): suspect an obstruction or a single motor.

Why It Happens

These are the causes I’d work through, in order:

1. No power reaching the base. A tripped breaker, a dead outlet or a failed surge protector.
2. Dead remote batteries. If the backlight won’t come on, this is the likely fix.
3. The remote is locked or unpaired. Many remotes have a lock button, and a remote can lose its pairing with the base.
4. The thermal switch tripped. Lift motors aren’t built for nonstop use.
5. Too much weight on one section. Bases are rated to lift a load spread across the whole platform, not piled on the head.
6. Something is in the way. A storage box, the wall, a cable, or the frame itself.
7. A failed motor or control box. Possible, but it’s the last thing to assume.

How to Fix an Adjustable Bed Not Going Up

1. Check the Power

Leggett & Platt’s chart lists these fixes when no features of the base work:

• Unplug the power cord, wait 30 seconds, and plug it back in to reset the electronic components.
• Check your breaker box for a tripped circuit.
• Test the outlet or surge protector by plugging in another appliance that you know works.

Leggett & Platt recommends a grounded surge protection device for its bases. If yours is plugged into an old power strip, that strip is worth suspecting.

Ergomotion adds a simple visual check: make sure the cord is firmly connected and the power supply’s indicator light is on.

2. Replace the Remote Batteries

Leggett & Platt’s fix for a remote with no backlight is new batteries. The remote in its current guide takes 2 AAA batteries. Ergomotion says most of its remotes use 3 AAA batteries and to replace all of them, even if the remote still lights weakly.

3. Unlock or Re-Pair the Remote

A locked remote looks broken. On Leggett & Platt’s remote, you press and hold LOCK for 5 seconds to lock or unlock it, and the backlight flashes 3 times. Ergomotion says that if the remote lights up but the bed ignores it, the remote has likely lost its pairing.

Pairing steps differ a lot by brand, so I’ve put them in a separate guide: how to reset adjustable bed remote.

4. Let the Motors Cool Down

This one surprises people. Leggett & Platt says its lift motors “are not designed for continuous use” and should run no more than 2 minutes in any 20-minute period, about a 10% duty cycle. Go past that and the thermal switch opens.

The fix is patience. Wait 30 minutes, then try again. In practice, that limit is easy to hit if you keep adjusting positions in one short session.

5. Take the Weight Off

Leggett & Platt rates the base in its guide for 850 lb (385 kg), including the mattress, spread evenly across the base. It adds that the base is not designed to lift that much on the head or foot section alone.

So if someone is sitting on the raised end, or you’ve stacked heavy items there, the section may stall. Leggett & Platt also says to get in and out with the base flat, and never to stand on it.

6. Clear Obstructions

Leggett & Platt’s chart says the mechanism may be obstructed and tells you to raise the base and look underneath. It also lists a head section sitting too close to the wall. Check for:

• storage bins or shoes under the bed
• a headboard or wall the head section hits as it rises
• cords caught in the frame, including heated blanket cables

That last one matters. Sunbeam says its heated bedding shouldn’t be used on a mechanically adjustable bed at all. If you’re getting error codes from one, see our electric blanket F2 guide.

How to Fix Adjustable Bed Motor Problems

If you’ve done all of the above and one section still won’t rise, the motor or control box may be the problem. Here’s where I’d draw the line on DIY.

Don’t open anything. Leggett & Platt says opening control boxes, motors or the remote (apart from the battery doors) voids the warranty, and repairs must be done by authorized personnel.

Don’t lubricate the lift motors. This one’s counterintuitive. Leggett & Platt says the motors are permanently lubricated and sealed, and that adding lubricant to the lead screws or nylon nuts can make the base creep downward from a raised position.

Isolate the fault, if your brand allows it. For its own bases, Ergomotion suggests swapping the head and foot motor cables. If the problem moves with the cable, the motor or port is at fault. If it stays put, the control box is the likely culprit. I’d unplug the base before touching any cables.

Then call the manufacturer or retailer with what you found. That information helps them send the right part.

When to Call for Service

Stop and contact the manufacturer if:

• nothing works after the power, battery and cool-down checks
• a section rises but won’t come down, and there’s no obstruction
• you hear grinding, or smell something hot from the control box
• the base was damaged in a move

Two adults should move an adjustable base, per Leggett & Platt, because of the injury risk. More frame and base guides are in our beds and frames section.

Frequently Asked Questions

Why is my adjustable bed not working at all?

Start with power. Check the breaker, test the outlet with another appliance, then unplug the base for 30 seconds to reset it. Replace the remote batteries if the backlight is off.

Why does my adjustable bed stop working after a few minutes?

The thermal switch may have tripped. Leggett & Platt says its lift motors should run no more than 2 minutes in a 20-minute period. Wait 30 minutes before trying again.

Can you fix an adjustable bed motor yourself?

Not inside the motor. Leggett & Platt says opening motors or control boxes voids the warranty and repairs should be done by authorized personnel. You can check power, batteries, pairing and obstructions yourself.

How do I lower my adjustable bed without power?

Some bases have a power-down box. On Leggett & Platt models with one, you insert 2 nine-volt batteries and press FLAT. Check your manual to see if yours has it.

How much weight can an adjustable bed lift?

It depends on the model. The Leggett & Platt base in its current guide is rated for 850 lb including the mattress, spread evenly, and less on the head or foot section alone.
