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.

HT-7120 Troubleshooting Guide 5

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.
