With my heart in my throat, I assembled my tools not knowing if I was going to fix it or screw it all up and have to buy very expensive new controllers. Here's what you need.
- Phillips screwdriver
- 4 Q-tips
- Cotton swab
Unplug the electric cord so you don't sock yourself and follow the directions under the pictures below.
First turn the controller over and remove the three screws. Gently lift off the bottom half.
Remove the screw from the circuit board and remove the board and the wires gently.
Note the carbon buildup on the contacts below the up and down controller buttons.
Remove the buildup by gently rubbing the affected area with a Q-tip moistened with alcohol. Immediately dry the area with a cotton ball so as not to damage the circuit board. Watch out as you do not to dislodge the LCD screen assembly.
Next clean the button contacts of any buildup. Gently rub with a Q-tip moistened with alcohol and dry immediately with a dry cotton ball to prevent damage to the contact.
If the screen assembly does fall out, don't worry. In the photo to the right, you see the screen and the plastic platform. There is a conductor pad stuck to the LCD screen. It's easily dislodged from the screen. Don't worry if if comes loose.
The circuit board looks like this if the LCD screen falls off. Don't worry. Everything sits in place and works fine. Nothing to worry about reconnecting.
To reset the LCD screen, first place the connector pad in the position shown in the top half of the plastic housing as shown.
Next lay the LCD screen face down in the frame and put the plastic platform over it with the solid top facing up.
Lay the circuit board face down over the buttons and screen on top of the front plastic plate. Align the center screw and tighten it down securely. Fit the cord into the mounting slot as shown.
Reset the back plate over the front plate and replace the three screws. Tighten the controller assembly and you're done.
Note the carbon residue left on the Q-tips. Flip the controller over. Plug the pump back in and give it a try. You'll find the controllers work as easily as they did when they were new. And you won't need a defibrillator because you had to buy new controllers.
That's all there is to it. It wasn't nearly as difficult as I feared it would be. This was a much easier project that I thought it would be. Fix it and your spouse will think you're a genius, especially if you don't show her (or him) this article. Let 'em think you are brilliant.

* If you attempt this repair while your bed is still under warranty it may mess up the warranty though I don's see why or how it would. Check out your paperwork first to see if there will be a problem. Likely not, though. If you've got wired controllers, your bed is probably way out of warranty by now. That said, we've never had any trouble with our Sleep Number beds other than the stiff controller buttons. Love our Sleep Number bed!
