Problem
Possible Cause
Solution
Make sure the circuit breaker is turned on.
Make sure the air gap (SET Button) is not pulled out.
Check junction box wires to ensure all connections are
tight and no bare wires are exposed.
The LED on my
KeypadLinc Dimmer is
not turning on at all and it
won’t control my light.
KeypadLinc Dimmer is not
getting power.
Check the light fixture to ensure all connections are tight
and no bare wires are exposed.
The switch I’m replacing
only has two wires.
KeypadLinc Dimmer needs a
NEUTRAL wire in order to
operate.
Look in the rear of the junction box for a group of white
wires all tied together with a wire nut. Those are the
NEUTRAL wires. Connect KeypadLinc Dimmer’s white
wire there.
The KeypadLinc Dimmer and
the Controller are on opposite
power line phases.
Make sure two Access Point Signal Enhancers are
properly installed to bridge signals between the two
power line phases.
The Controller is plugged into
a power strip.
Power line signals can’t travel through power filters.
Plugging the Controller directly into a wall outlet works
best.
My KeypadLinc Dimmer
is not receiving signals
from INSTEON or X10
Controllers.
Other modules are absorbing
the signal.
Move the other modules or the Controller to another
outlet.
Add new INSTEON devices or move around existing
INSTEON devices. All INSTEON devices act as
INSTEON Network repeaters.
My KeypadLinc Dimmer
is not linking to or
working with an
INSTEON Controller or
Device.
The INSTEON signal may be
too weak.
Make sure you are not experiencing interference with
older X10 BoosterLinc technology. Upgrade to
INSTEON BoosterLincs.
My KeypadLinc Dimmer
doesn’t always respond
to an INSTEON
Controller.
The INSTEON Controller
may have been reset without
first unlinking KeypadLinc
Dimmer from it.
Re-link KeypadLinc Dimmer to the INSTEON Controller.
Check scene membership and remove any unwanted
links from KeypadLinc Dimmer, or perform a Factory
Reset to clear it.
Install a power line signal blocker in your home to keep
X10 signals from neighboring homes from interfering.
Consider not using KeypadLinc Dimmer in X10 mode.
The light turned on by
itself.
Another Controller, a timer, or
stray X10 signals triggered
KeypadLinc Dimmer.
If the above doesn’t work, perform a Factory Reset.
The controlled light does
not appear to turn on or
off right away.
The Ramp Rate may be set
too slow.
Set a shorter Ramp Rate.
Install a power line noise filter like Smarthome’s #4835
between the load and KeypadLinc Dimmer.
Install additional INSTEON Devices to boost the
INSTEON signal.
KeypadLinc Dimmer
turns on, but not off,
using another Controller.
The load is producing
electrical noise that is
interfering with KeypadLinc
Dimmer’s reception of power
line signal.
Increase the X10 signal strength with an INSTEON-
compatible X10 booster to overcome the power line
noise.
My light only turns off
when I tap the On Button
on my KeypadLinc
Dimmer, but I can
brighten and dim it.
The On-Level may be set to
fully-off or very dim.
Set a brighter On-Level. See

LEVELS AND RAMP RATES
