HT-7450 Troubleshooting Guide 1

HT-7450 Troubleshooting

This Troubleshooting Guide walks you step-by-step through the

diagnosis of HT-7450 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.

The Width LEDs on the

foot and calf massager

are flashing

Verify that the cables connecting the backrest

to the left-hand side of the chair base are

securely connected. If the connection is

secure, there is a faulty power connection

within the chair. Replace the chair base. If this

does not solve the problem, replace the

backrest.

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 massage functions are not working,

replace the backrest.

2HT-7450 Troubleshooting Guide

My heat is not working

properly

See "Heat" on page 4.

My Massage Comfort

Control is not working

properly

See "Massage Comfort Control" on page 5.

My seat massage is not

working properly

• If the seat massage does not work at all—the

air pump is not working properly. Replace

the chair base. DEALER NOTE: You may

wish to replace the air pump assembly

instead of the chair base.

• The seat massage air bags inflate, then stay

inflated, or only partially inflate—replace the

chair base.

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.

See "Backrest Recline/Incline" on page 6.

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 won’t

raise/lower

If the foot and calf massager will not raise or

lower, and the remote beeps when you push

the legs up and legs down buttons, replace the

foot and calf massager actuator.

If replacing the actuator does not solve the

problem, the problem may be in the module

that controls the actuator. Replace the chair

base.

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.

If the width LEDs do not light, see "Resetting

the Foot and Calf Massager Width LEDs" on

page 4 for further instructions.

My convenience outlet

is not working

See "Convenience Outlet" on page 6.

To Troubleshoot This

Issue: Do the following:

HT-7450 Troubleshooting Guide 3

Power

Step 1: Check the power cord

1. Verify that the power cord connection to the chair’s power panel is

secure and that the cord is not damaged.

2. If the power cord is damaged, replace the power panel.

Step 2: Check the wall outlet

1. Plug a different device into the AC outlet into which the chair is

plugged.

2. 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 left 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 your fingers, open the fuse compartment on the power panel,

then turn the left-hand fuse holder knob (located on the power

panel) counter-clockwise to remove it.

3. Replace the fuse with a new fuse of the same rating.

4. Reinsert the fuse holder into the power panel, then turn it clockwise

to secure it.

5. Close the fuse compartment lid.

6. Plug the chair back into the wall outlet and turn it on.

7. Verify that the chair is now receiving power.

Step 4: If the chair is still not receiving power, replace the

chair base

If this does not solve the problem, replace the backrest.

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

locate the function that is not working in the troubleshooting table.

Resetting the Foot and Calf Massager Width LEDs

To reset the foot and calf massager width LEDs:

1. Press and hold the (—) button until the massager reaches its

narrowest position.

2. Press and hold the (+) button until the massager reaches its widest

position.

3. Verify that the LEDs are now working properly. If they are not,

replace the foot and calf massager.

Heat

IMPORTANT

The heater heats slowly, taking at least five minutes to warm

up.

1. Press the Heat button on the remote control (the Heat LED lights).

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-7450 Troubleshooting Guide 5

Massage Comfort Control

This section assumes that the air bags are not inflating/deflating as you

adjust the Massage Comfort Number.

1. While adjusting the Massage Comfort Number, listen carefully for

the sound of the air pump.

2. If you can hear the air pump running softly:

a. Check the air tubing connection to the back of the left-hand

armrest to make sure the connection is secure.

b. Remove the tubing from the armrest, then check to see if the

white plastic end of the fitting has broken off and is stuck inside

the armrest. If this is the case, replace the tubing/fitting.

3. If you can hear the air pump running loudly:

a. Using two hands, pull outward on the left-hand side panel to

separate it from the chair.

b. Check to see if the air hose tubing has detached from the fitting.

c. If the tubing is detached from the fitting, reattach it, then secure

it by sliding the white zip tie firmly over the fitting connection.

4. If you cannot hear the motor running, the air pump is not working

properly. Replace the chair base.

DEALER NOTE: You may wish to replace the air pump instead of the

chair base.

6HT-7450 Troubleshooting Guide

Backrest Recline/Incline

The remote beeps once when Recline/Incline buttons are

pushed:

If you hear a single beep when you push the Recline and Incline

buttons, it means the backrest actuator is receiving power. Therefore the

actuator itself is not working properly. Replace the backrest actuator.

The remote beeps twice when Recline/Incline buttons

pushed:

If the backrest is in a fully inclined position and you hear two beeps

when you push the Recline button, it means the safety sensor has likely

failed.

1. Make sure that nothing is pressing on the safety sensor.

2. Tap the safety sensor with your foot to ensure that it didn’t get stuck

during shipping.

3. If the problem still exists, replace the rear shroud.

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 right of the two fuses, located on the

the power panel at the rear of the chair base.

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 your fingers, open the fuse compartment on the power panel,

then turn the left-hand fuse holder knob (located on the power

panel) counter-clockwise to remove it.

5. Replace the fuse with a new fuse of the same rating.

6. Reinsert the fuse holder into the power panel, then turn it clockwise

to secure it.

7. Close the fuse compartment lid.

8. Plug the chair back into the wall outlet and turn it on.

9. If the convenience outlet is still not receiving power, replace the

power panel.
