HT-7120 Troubleshooting Guide 1
HT-7120 Troubleshooting
This Troubleshooting Guide walks you step-by-step through the
diagnosis of HT-7120 customer problems. 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 3.
My remote control is
not working properly See "Remote" on page 4.
My backrest is not
massaging properly
If the Kneading, Percussion, Compression or
Rolling functions are not working, replace the
backrest.
My Stretch function is
not working
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).
My Heat function is
not working See "Heat" on page 4.

2HT-7120 Troubleshooting Guide
My backrest won’t
recline/incline
Make sure you are pressing and holding the
recline/incline button for at least five seconds; it
can take several seconds to activate the
actuator.
If this does not help, replace the backrest
actuator.
My foot and calf
massager is not
massaging properly
If the foot and calf massager hesitates while
changing directly, this is due to the gears
shifting, and is perfectly normal.
If the foot and calf massager is only massaging
on one side, or not massaging at all, replace
the foot and calf massager.
My foot and calf
massager width control
is not working properly
The foot and calf massager width adjustment is
subtle; therefore the difference between the
settings may not be visually noticeable.
You must press and hold the width buttons to
adjust the width setting. Some LEDs may not
light as the width is adjusted to the new setting,
however when you release the width button the
LEDs indicate the current setting.
My foot and calf
massager won’t
raise/lower
See "Foot and Calf Massager" on page 5.
My Massage/Comfort
control isn’t working
Place your hand on the front left or right side of
the backrest while adjusting the Massage
Comfort Control. If the air bags are not inflating
or deflating, check the tubing that connects the
air pump to the backrest for kinks. If there is a
kink, cut the kinked portion of the tubing off,
then reconnect the tubing to the fitting. If this
does not solve the problem, the air pump is not
working. Replace the chair.
DEALER NOTE: You may wish to replace the air
pump instead of replacing the chair.
My chair won’t swivel
or the pedestal is
broken.
Replace the chair.
My convenience outlet
doesn’t work. See "Convenience Outlet" on page 5.
To Troubleshoot This
Issue Do the following:

HT-7120 Troubleshooting Guide 3
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 power panel, and
instruct the customer to note it as well. Once the power panelis
replaced, the chair will no longer contain the serial number on
the power panel.
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: Replace the AC Outlet Fuse
The AC outlet fuse is the right of the two fuses, located on the power
panel.
To replace the fuse:
1. Turn the power switch to OFF and unplug the chair from the wall
outlet.
2. Using a small screwdriver or a coin, turn the fuse holder (located on
the power panel) approximately 1/8 turn counter-clockwise.
The fuse holder pops out.
3. Replace it with a new fuse of the same rating.
4. Reinsert the fuse holder into the power panel, then turn it 1/8 turn
clockwise to secure it.
5. Plug the chair back into the wall outlet and turn it on.
6. Verify that the chair is now receiving power.

4HT-7120 Troubleshooting Guide
Step 3: If the chair is still not receiving power, replace the
backrest.
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.
Heat
IMPORTANT
The heater heats slowly, taking at least five minutes to warm
up.
1. Press the Heat button on the remote control.
2. Watch the remote control timer until it counts down at least five
minutes.
3. Check the left and right sides of the backrest to determine if either
side feels warm.
4. If either side does not feel warm, replace the backrest.

Foot and Calf Massager
The foot and calf massager will not deploy or retract:
1. Make sure the electric footrest lever is being pulled up or pushed
down long enough for the foot and calf massager to shift into gear (it
takes a few seconds).
2. Pull up and then push down on the electric footrest lever, located on
the right-hand side of the chair.
3. Do one of the following:
• If the foot and calf massager actuator is not making any sound,
replace the foot and calf massager actuator.
• If 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 canbe corrected byremoving
the foot and calf actuator, allowing the bracket to swing down into
the proper position, then reinstalling the actuator. See repair
instruction sheet “Replacing the Foot and Calf Massager
Actuator” for instructions. If this procedure does not resolve the
problem, replace the foot and calf massager actuator.
Convenience Outlet
NOTE
This section pertains to 120-volt products only; 230-volt
products do not contain convenience outlets.
The convenience outlet fuse is the left of the two fuses, located on the
bottom of the power panel.
1. Verify that the device being plugged into the convenience outlet
does not draw more than 1 Amp of power. (If it does, it cannot be
plugged into the convenience outlet as it will blow the fuse).
2. Verify that the device being plugged into the convenience outlet
works when plugged into a wall outlet.
3. Turn the power switch to OFF and unplug the chair from the wall
outlet.
4. Using a small screwdriver or a coin, turn the fuse holder (located on
the power panel) approximately 1/8 turn counter-clockwise.
The fuse holder pops out.

6HT-7120 Troubleshooting Guide
5. Replace the fuse with a new fuse of the same value.
6. Reinsert the fuse holder into the power panel, then turn it 1/8 turn
clockwise to secure it.
7. Plug the chair back into the wall outlet and turn it on.
8. If the convenience outlet is still not receiving power, replace the
backrest cover.
