HT-5270 Troubleshooting Guide 1

HT-5270 Troubleshooting

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

diagnosis of HT-5270 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. Verify that the

problem still exists.

2. If there is no movement on the chair when you power it on (the

backrest massage mechanism and the foot and calf massager

paddles do not move), see "Power" on page 3.

3. Turn the power switch on the back of the chair to Off, wait

approximately five seconds, then turn it back On.

4. Wait 30 seconds while a system check is performed, observing

whether the back massage mechanism and foot and calf

massager paddles move during the system check, then check to

see if any of the following are true:

• The Rolling and Zone LEDs are flashing—This means the

elevation motor is not operating correctly. Replace the chair.

• The back massage mechanism did not move during the system

check—This means that the kneading motor is not operating

correctly. Replace the chair.

• The foot and calf massager paddles did not move during the

system check —This means that the foot and calf massager

motor is not operating correctly. Replace the foot and calf

massager.

IMPORTANT

There is no way to distinguish between the foot and calf

massager motor or the PCB as the root cause of the problem. If

replacing the foot and calf massager does not solve the

problem, replace the chair.

5. Choose from the following:

To Troubleshoot This

Issue: Do The Following:

My remote control is

not working

If one or more remote control LEDs do not light,

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.

Replace the remote.

If the remote control LED lights but the function it

controls is not working properly, the problem is

most likely in one of the components controlled

by the remote, not in the remote itself See

"Massage Functions" on page 4 for further

diagnosis.

My chair is not

massaging properly

See "Massage Functions" on page 4.

My foot and calf

massager is not

working

See "Foot and Calf Massager" on page 3.

My chair 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.

See "Recline/Incline" on page 4 for further

diagnosis.

HT-5270 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

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 4: Replace the chair

An electrical surge may have bypassed the fuse and damaged the main

PCB. Replace the chair.

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 will not deploy or retract:

1. Press the foot and calf massage button on the remote control, then

wait 30 seconds.

2. If the foot and calf massager begins massaging but will not deploy or

retract, the foot and calf massager actuator is not working properly.

This actuator is not replaceable. Replace the chair.

4HT-5270 Troubleshooting Guide

The foot and calf massager will not massage:

IMPORTANT

Make sure the foot and calf massager is fully deployed, as it

must be fully deployed to work.

This means that either the foot and calf massager motor sensor is not

operating correctly or there is a broken wire connecting the foot and calf

massager to the backrest. Replace the foot and calf massager.

The foot and calf massager vibration is not working:

The vibration motor is not working properly. Replace the foot and calf

massager.

Massage Functions

Follow the steps in this section to troubleshoot massage functions that

are not working properly.

Recline/Incline

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.

To Troubleshoot This

Issue: Do The Following:

My Percussion

massage is not working

Press the Percussion button on the remote

control. If the percussion massage does not work,

the percussion motor is not working properly.

Replace the chair.

My Kneading massage

is not working

Press the Kneading button on the remote control.

If the kneading massage works for approximately

30 seconds then stops, the kneading motor

sensor is not working properly. Replace the chair.

My Rolling massage is

not working

Press the Rolling button on the remote control. If

the massage works for approximately 30 seconds

then stops, the elevation motor sensor is not

working properly. Replace the chair.

HT-5270 Troubleshooting Guide 5

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 safety sensor.
