Question about Human Touch Massage Chair HT-7120 - Butter PU Synthetic Leather

1 Answer

HT-7120 massage roller assembly travels down full length, but won't come back up. You can hear the motor run. It's as if the limit doesn't cause roller assembly to travel back up.

Better to show your massage chair to some expert. For the time being you can use a vending massage chair.

Resetting motor of a dominator garage door


Doe the motor have a battery back-up, or mains only?
Step 1: Disconnect the linking arm from the motor traveller, and test (by pressing button on remote or wall console), that motor runs traveller to the fully open position, and stops where the "open" limit switch is. Then run motor (by pressing button on remote or wall console), to the fully closed position. If the motor fails to run through a full open/ full close cycle, the limit switches require checking.Assuming that the motor runs through the full open/full closed cycle, focus on the door. All motors have built in circuitry, preventing motors from crushing objects. A double garage door should be able to be lifted easily by one hand. The door should be able to be left at any height, and remain there, or creep ever so slowly downwards (travel time of approx 10mm per 5 seconds is ok). If your door is properly balanced, and the motor will still not lift it, the control card on the motor is damaged, and requires replacement.

The motor that moves up and down the back does not work.


That motor is located at the base of the backrest unit. It operates a lead screw drive that positions the kneading/tapping motors and rollers. The motor is controlled by the PCB unit that covers the length of the back of the massaging unit. Human Touch will not sell individual replacement parts. They will sell only the entire backrest assembly for $600 plus $60 shipping. It can be replaced without tools in less than five minutes.

THE MODEL IS EP578.ROLLERS DONT MOVE BUT MOTOR IS FUNCTIONING.LIGHTS IN THE REMOTE ARE BLINKING ALL TOGETHER THEN THE MACHINE STOPS.


I found with my Panasonic EP578 that, if the lower photo sensor limit switch gets too dusty, the massage mechanism will travel downwards past the normal range of motion and the electronics will time out because the unit did not get a down limit sensor signal & reverse direction and proceed back to the upper limit switch in time. With the device unplugged, I simply removed the grommet screws and opened the fabric backing. Then I removed the units cover and Then blew out dusty photo sensors with compressed air. Then I swapped the red and green, 2-pin mag clutch coil connector plugs so that when I switched the unit on again I could make the unit travel back up to about, the scapular position. The reason that this is possible is that when you first start a normally working machine, the first thing that happens after the motor turns on, is that the motor clutch for the mechanism that provides the neck and vertebral massage balls, also energizes. I figured that I could get the voltage at that connector to energize the rolling clutch to get the unit back up again (as you can't move it by hand). Then I turned the unit off (while stile in cycle) and the swapped the mag-clutch coil connectors back to their original position. Re-starting the machine causes the moving massage mechanism to go through it's Power On Routine which realigns everything to it's 'Home' position and ready to run a fully functioning cycle. Remember to unplug the machine when working on it and keep all fingers, necktie, hair, jewelry from moving mechanism when it's moving to avoid damage to the machine and bodily harm to yourself!

Calf and foot massager does not go up and down. Switch clicks, motor hums, piston does not move. What do you think? Thanks, Brian Shore 315-956-2065


It sounds like the piston assemby might be jammed. The motor will hum since it's trying to run, but will just buzz if the output isn't turning. Otherwise, it could be a broken part in the piston assembly. You will have to partially disassemble the chair to see what's going on. If it's under warranty, contact Human Touch. The same for replacement parts.
Good luck, and hope this helps.

The rollers will not go up and down anymore; looked inside and everythink seems intact


Your set up is most probably: an electric motor turns a worm gear that turns a large spur gear that turns a smaller spur gear that rides on a rack gear. The smaller spur gear (pinion) that rides the rack (yes, as in rack-n-pinion), allowing the up-and-down travel of the massage balls, has broken teeth which may not be visible because it's hidden under the larger spur gear. They are all plastic gears with lots of white grease.
