Troubleshooting
Problem
Possible Cause
Solution
LED won’t come on.
SwitchLinc is not getting power.
Make sure circuit breaker is on.
Check the junction box wires to ensure all
connections are tight and no bare wires are
exposed.
Check that a standard incandescent bulb rated for
25W or more is installed.
SwitchLinc won’t add to
scene as a responder.
The controller may have dropped out of
Add to a Scene mode, or added
another device.
Try re-adding SwitchLinc to the controller again.
The INSTEON signal may not be
reaching the “vicinity” of SwitchLinc.
Make sure phases are detected, add additional
INSTEON devices and/or move around existing
INSTEON devices.
Controller is a powerline-only device.
(SwitchLinc 2-Wire is RF only.)
You'll need to add an INSTEON Access Point or
dual-band device to allow communication between
powerline-only and RF-only devices.
The controller turns
SwitchLinc off but not on.
Ramp rate may be extremely slow
Re-add SwitchLinc to controller with a faster ramp
rate. See
SwitchLinc may be added to the scene
in the Off state.
Turn on the light and re-add SwitchLinc to the
controller scene.
SwitchLinc is taking a long
time to respond to a
controller.
The controller may be sending
commands to a different responder that
is no longer in use. Commands for the
unused responder are being resent and
slowing down communication signals to
SwitchLinc.
Remove any unused responders from the scene via
the controller.
HINT: If you are using home automation software,
you can easily check and eliminate unnecessary
scene memberships.
If the above doesn’t work, perform a factory reset
on the controller
Ramp rate may be extremely slow.
Remove and re-add SwitchLinc to controller with a
faster ramp rate. See
The load turned on by
itself.
Another controller or a timer could have
triggered SwitchLinc.
Monitor for recurrence and remove device from the
SwitchLinc’s scene if you can determine the cause.
If necessary, perform a factory reset.
The load doesn’t appear to
turn on right away.
The ramp rate may be set too slow.
Set a faster ramp rate. See
SwitchLinc is locked up.
A surge on the powerline may have
caused a glitch.
Remove power to SwitchLinc by pulling out the Set
button to create an air gap for 10 seconds, then
pushing it back in. If that doesn’t work, perform a
factory reset.
The lights flicker when on
and SwitchLinc repeatedly
turns the load off and on.
The SwitchLinc is not getting enough
power from the light bulb. The
SwitchLinc “steals” some of the bulb’s
wattage for powering its circuits.
Change the light bulb to a standard incandescent
bulb of at least 25W. You can always set the
brightness to a lower level and still have the effect
of a small-wattage bulb.
If you have tried these solutions, reviewed this Owner’s Manual, and still cannot resolve an issue you are having with
SwitchLinc, please call the INSTEON Support Line at 800-762-7845.
