PC-086 Troubleshooting Guide 1
PC-086 Troubleshooting
This Troubleshooting Guide walks you step-by-step through the
diagnosis of PC-086 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. Unplug the chair, wait approximately five seconds, then plug it
back in.
2. Verify that the chair is receiving power by pressing a button on the
control panel to ensure the corresponding LED lights. If the LED
does not light, see "Power" on page 2.
3. If the problem still exists, choose from the following issues:
To Troubleshoot This
Issue Do the following:
My chair will not
recline/incline
See "Electric Recline" on page 3.
The wave function is
not working properly /
is noisy
See "Wave" on page 3.
The jade/heat is not
working
NOTE: The jade stones heat slowly, and the heat
automatically turns off after 30 minutes, as this is
the recommended duration.
If the chair does not heat after several minutes,
replace the backrest pad.
My chair makes noise
when I incline/recline.
See "Noise" on page 4.

Power
Step 1: Check the power cord.
1. Check the entire length of the power cord for damage; if the power
cord is damaged, replace the power cord.
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: If the chair is still not receiving power, replace the
main PCB box and the power cord.
My chair feels bumpy
when reclining
The complex mechanism that enables the
footrest to continue to fold inward after the chair
is fully inclined creates a slight bump when
reclining, as it locks, and when inclining, when it
unlocks.
My recline lever is
broken.
Replace the left-hand armrest (w/lever).
My footrest is broken. Replace the mechanical footrest assembly.
My footrest pads drag
on the ground when I
fully retract the
footrest.
When installing the seat pad, the lower corners of
the footrest frame must be installed into the
corresponding holes in the bottom corners of the
seat pad, otherwise the bottom of the seat pad
will not retract along with the footrest.
To Troubleshoot This
Issue Do the following:

PC-086Troubleshooting Guide 3
Electric Recline
The Chair Recline/Incline Works Intermittently
If your chair reclines/inclines intermittently, requiring you to unplug it
from the wall outlet and plug it back in, be sure you are holding the lever
in the recline or incline position for five seconds. It takes several
seconds for the recline actuator to engage. If you pull and push the lever
back and forth in different directions, the recline actuator cannot
engage in any particular direction.
The chair will not recline or incline.
1. Verify that the chair is plugged into a working wall outlet.
2. Replace the recline actuator.
3. If replacing the recline actuator does not resolve the problem,
replace the left-hand armrest (containing the electric recline lever).
Wave
The wave function is very noisy.
NOTE
A slight humming noise is normal when the wave function is in
use.
1. Verify that the backrest air hose connecgtor is connected to the seat
air hose connector, and secure the two together using a zip tie
(available at any hardware store or from HumanTouch).
2. Replace the air compressor assembly.
The wave function does not work at all and you do not hear
a normal humming noise from the air compressor.
1. If the wave function works for awhile after powering the chair off and
back on, but then stops working, and you have experienced this
pattern more than once, replace the PCB.
2. If the wave function does not work in either the backrest or the seat,
replace the air compressor assembly.

4PC-086 Troubleshooting Guide
The wave function does not work at all but you hear a
normal humming noise from the air compressor.
1. Using the instructions for Replacing the Air Compressor as a
reference, verify that the air hoses from the chair are connected to
the air compressor.
2. Using the instructions for Replacing the Backrest Pad or Seat Pad,
verify that the respective air hose connector “banks” from each pad
are connected to the corresponding connector “banks” in the chair
seat.
3. If the problem persists, replace the air compressor assembly.
The wave function works in the seat but not in the backrest
(or vice versa).
Replace the chair.
Noise
It is important to distinguish between typical noises caused by
upholstery rubbing together, clicking of the electronic recline switch, or
normal functioning of the folding footrest assembly from those that are
out of the ordinary.
Rubbing or squeaking sound
This noise is normal, caused by the body pad rubbing against the side
of the chair. To minimize this noise, Do the following:
1. Reinstall the pads, ensuring that they are centered carefully during
installation.
2. Check to see if there is less clearance between the backrest and the
sides of the chair on one side of the chair than there is on the other. Try
to center the backrest between the two sides of the chair (like you would
a bicycle tire between the two brake pads).
Soft clicking sound when engaging the recline handle
This noise is normal.
Slight mechanical noise when reclining or inclining
The complex mechanism that enables the footrest to continue to fold
inward after the chair is fully inclined emits a minor mechanical sound
when reclining, as it locks, and when inclining, when it unlocks.

PC-086Troubleshooting Guide 5
Loud popping or clunking sound when reclining
This may indicate a known issue with an earlier version of the footrest
rod and bracket, in which the rod popped upward in the bracket toward
the end of the reclining movement. This in no way affects the
functioning of the chair. However, to resolve this noise issue, replace the
footrest rod/bracket with the newer version. Chair with serial numbers
greater than B863111041 already have the newer-version bracket
installed.
