HT-140 Troubleshooting Guide 1
HT-140 Troubleshooting
This Troubleshooting Guide walks you step-by-step through the
diagnosis of HT-140 customer issues. It is important to follow these
steps carefully, to ensure that the problem is diagnosed correctly, and
therefore the appropriate repair action is taken.
Getting Started
1. Turn the power switch on the back of the chair to Off, wait
approximately five seconds, then turn it back On.
2. Wait 30 seconds while a system check is performed, then verify
that the problem still exists.
3. If the problem still exists, choose from the following issues:
To Troubleshoot This
Issue: Do The Following:
There is no movement
on the chair when I
power it on
The backrest massage mechanism and the
foot and calf massager paddles should move
when you power on the chair. If they do not,
see "Power" on page 2.
My remote control is
not working
See "Remote" on page 3.
My backrest is not
massaging properly
If the Percussion, Compression, Kneading or
Rolling massage is not working properly,
replace the backrest.
If the Stretch feature is not working properly,
make sure you are pressing and holding the
Stretch button until the chair beeps twice (it
takes several seconds for the chair to prepare
for the Stretch function).

Power
Step 1: Check the power cord.
Verify that the power cord connection to the power panel is secure, and
that the cord is not damaged. If the power cord is damaged, replace the
backrest cover.
IMPORTANT
Be sure to note the serial number on the back of the backrest
cover. Once the backrest cover is replaced, the chair will no
longer contain the serial number.
Step 2: Check the wall outlet.
Plug a different device into the AC outlet into which the chair is plugged.
If the device does not work (is not receiving power), the AC outlet is
most likely not working. Plug the chair into a different AC outlet to verify
that it receives power.
Step 3: If the chair is still not receiving power, replace the
backrest.
A recent electrical surge may have damaged the main circuit board.
Replace the backrest.
My backrest won’t
recline/incline
Make sure you are pressing and holding the
recline or incline button for at least five
seconds; it can take several seconds to
activate the actuator.
If this does not help, the backrest actuator is
not working properly. Replace the backrest
actuator.
My foot and calf
massager is not
massaging properly
See "Foot and Calf Massager" on page 3.
My foot and calf
massager won’t
raise/lower
See "Foot and Calf Massager" on page 3.
My chair won’t swivel
or the pedestal is
broken.
Replace the chair.

IMPORTANT
If you replace the backrest, be sure to note the serial number
on the backrest cover. Once the backrest is replaced, the chair
will no longer contain the serial number.
Remote
If one or more remote control LEDs do not light when you
push the corresponding button, but the function the button
controls works properly:
The remote control is not working properly. Verify that the remote control
cable connection to the backrest cover is secure. If that does not solve
the problem, replace the remote.
If the remote control LED lights but the function it controls
is not working properly:
The problem is most likely in the function controlled by the remote, not
in the remote itself. See "Getting Started" on page 1 and locate the
function that is not working in the troubleshooting table.
Foot and Calf Massager
If the foot and calf massager hesitates when changing
direction:
This is due to the gears shifting, and is perfectly normal.
If the foot and calf massager will not raise or lower:
1. Press the foot and calf button on the remote control, then wait 30
seconds.
2. Do one of the following:
• If the foot and calf massager does not activate, and after 30
seconds all foot and calf massager LEDS begin to flash, replace
the backrest.
DEALER NOTE: You may wish to replace the choke coil instead
of the complete backrest assembly.
• If you hear a clicking sound and the foot and calf massager
actuator is making a humming sound, the foot and calf massager
bracket may have been pushed up into the chair seat. This can

be corrected by removing the front foot and calf actuator hinge
pin, allowing the bracket to swing down into the proper position,
then reinstalling the hinge pin. See the Foot and Calf Massager
Actuator repair instructions for details. If this procedure does not
resolve the problem, replace the foot and calf massager actuator.
If the foot and calf massager massages only on one side:
Replace the chair.
If when you press the foot and calf massager button on the
remote control the foot and calf massager paddles do not
move and all foot and calf massager LEDs are all flashing:
• If the serial number is prior to A21061221, replace the backrest.
DEALER NOTE: You may wish to replace the choke coil instead
of the complete backrest.
• If the serial number is after A21061221, replace the chair.
