HT-1650 Troubleshooting

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

diagnosis of HT-1650 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

To begin:

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:

4. Choose from the following:

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 foot and calf

See "Foot and Calf Massager " on page 4.

Power

Step 1: Check the power LED.

Check the status of the power panel LED, located on the back of the

left-hand armrest above the power switch. If the power LED lights, go to

“Step 4: Replace the AC outlet fuse.”

Step 2: Check the power cord.

1. Verify that the power cord is plugged securely into the chair’s power

panel and is not damaged.

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

3. If the power cord connection is not secure, secure it, then recheck

the power LED status.

4. If the power LED lights, but there is still no massage mechanism

movement, see "Step 4: Replace the AC outlet fuse" on page 3.

Step 3: 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.

My arm vibration

started automatically

and cannot be turned

off by pressing the

Arms button on the

remote control.

If this occurs, there is a problem with the circuit

board. Replace the backrest:

DEALER NOTE: You may wish to replace the

daughter board instead of the complete backrest

assembly.

My chair is not

massaging properly See "Massage Functions" on page 5.

My backrest won’t

recline/incline See "Recline/Incline" on page 9.

My convenience outlet

is not working. See "Convenience Outlet" on page 10.

To Troubleshoot This

Issue: Do the following:

HT-1650 Troubleshooting Guide 3

Step 4: Replace the AC outlet fuse

Even though the power panel LED (located on the back of the left-hand

armrest) is lit, the AC outlet fuse may still be blown or broken, which

interferes with the remote control function. Replace the 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, turn the fuse holder knob (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 remote control LEDs now light.

Step 5: If the chair is still not receiving power, 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 "Massage Functions" on page 5 for further

diagnosis.

Foot and Calf Massager

The foot and calf massager hesitates when changing

directions:

This is due to the gears shifting, and is perfectly normal.

The foot and calf massager circulate function will not shut

off:

If this occurs, there is a problem with the circuit board. Replace the backrest:

The foot and calf massager is not massaging, vibrating,

retracting or deploying:

IMPORTANT

The foot and calf massager must be fully deployed and locked

into position with the massage wells facing up for the foot and

calf massage and circulation functions to work.

1. Using the remote control (Legs Down button), attempt to fully retract

the foot and calf massager until it beeps twice, and then fully deploy

it until it beeps twice.

2. If the foot and calf massager will not retract/deploy, do the following:

a) Pull up on the foot and calf massager rotation release handle,

then rotate the foot and calf massager away from the chair

until you hear and feel it lock into place. The smooth side of

HT-1650 Troubleshooting Guide 5

the foot and calf massager is now facing up.

b) Pull up on the foot and calf massager rotation release handle,

then rotate the foot and calf massager back toward the chair

until you hear and feel it lock into place.

c) Without pulling the rotation release handle, gently try to rotate

the foot and calf massager away from the chair again. It

should be locked in place, unable to rotate.

d) Reattempt to retract/deploy the foot and calf massager. If the

foot and calf will still not retract/deploy, a sensor in the chair

base is not working properly. Replace the chair base.

3. If the foot and calf massager circulation function is not working,

replace the foot and calf massager.

Heater

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.

Arm vibration

Determine whether the vibration is not working in just one arm or both

arms, then do one of the following:

• If the vibration is not working in one arm only, replace the

vibration unit in that armrest.

• If the vibration is not working in both arms, replace the backrest.

DEALER NOTE: You may wish to replace the daughter board

instead of the complete backrest assembly.

My After Work Stretch

(Program 5) is not

working

Make sure the voice response switch, located on

the back of the chair, is set to On. After selecting

the After Work Stretch program (5), the voice

system instructs the user to press and hold the

Recline button until it beeps twice.

Seat massage

Choose from one the following seat massage issues:

• The seat massage does not work at all—see "The seat massage

does not work at all" on page 7.

• The seat massage air bags partially inflate, then stay inflated—

see "The seat massager partially inflates, then stays inflated" on

page 8.

• The seat massage works, but when you turn off the seat massage

the air bags stay inflated—Replace the backrest.

DEALER NOTE: You may wish to replace the daughter board

instead of the complete backrest assembly.

The seat massage does not work at all

wire that is not connected properly. Do the following:

1. Power off the chair.

2. Facing the back of the chair, locate the side panel on the lower

right-hand side.

3. Using a Phillips-head screwdriver, remove the two screws that

secure the side panel, then remove the side panel by pulling gently

on the cables to release it from the chair frame. (The side panel

remains attached to the air hose).

4. Locate the large connector behind the side panel, then disconnect

it.

5. Gently pull on the wires that lead to the large connector. If any of the

wires comes out of the connector, this confirms that this wire

connection is the problem.

6. Push the wire into the connector until it clicks, then pull gently on

the wire to confirm that it cannot come out of the connector.

7. Reconnect the two connectors you disconnected in step 4.

8. Push the cables and connectors back into the lower right-hand side

of the chair. The large set of cables fits into the slot on the end of the

side panel.

secure the side panel, then remove the side panel by pulling gently

on the cables to release it from the chair frame. (The side panel

remains attached to the air hose).
