Troubleshooting
Dimmer Module LED does not turn on
It is possible your Dimmer Module is not receiving power. If the attached load can still be controlled, It is possible
that the status LED has been disabled.
Try this:
• Test Dimmer Module in a different power outlet. If the LED illuminates when using a different outlet, check
the original outlet for power. Some outlets are controlled by a switch elsewhere in the room. Avoid switched
outlets as they disable your INSTEON device when turned off.
• If the outlet works and the connected lamp can be toggled, use software or the Local Programming
Flowchart to change the behavior of the status LED. The status LED brightness can be dimmed to the
point that it appears off. The INSTEON Hub and other central controller software allow setting of this device
property.
Unable to add Dimmer module to a scene as a controller or a responder
If the device has power, something is likely interfering with the INSTEON signal. Large appliances, power strips
and some electronic devices may generate powerline noise.
Try this:
• Check to see if you have connected Dimmer Module to a power strip, surge suppressor, backup battery or
AC line filter. These devices often filter out the INSTEON powerline signal. Relocate the Dimmer Module to a
standard AC outlet.
• Large appliances like refrigerators or air conditioners may be generating powerline noise that is disrupting
the INSTEON signal. If the issue only appears to happen when one of these large appliances is running,
install a noise filter at that device. If you are uncertain of the device generating the noise, disconnect the
potentially offending devices from power and test your Dimmer Module again. If the issue is resolved, install
noise filters at each offending appliance.
• Some small electronics devices that include an AC/DC power supply can generate substantial electrical
noise, in some cases, enough to disrupt an entire house of INSTEON devices. Search your home for
speaker docks, small stereos, etc. and disconnect them from power to perform testing. If removing these
devices from your powerline resolves the INSTEON issue, install a noise filter at each offending small
electronic appliance.
• Your Dimmer Module may be too far from another INSTEON device to receive a signal. Try locating the
Dimmer Module closer to another INSTEON device and if the issue is resolved, install a Range Extender
or other Dual-Band INSTEON device between the intended location of your Dimmer Module and the next
nearest INSTEON device.
The Dimmer Module is slow to respond to commands from a controller
This issue most likely lies with the controller, not the Dimmer Module; the controller is most likely repeating
commands not acknowledged by an INSTEON device that has been removed from the network. The repeated
commands are slowing down the INSTEON network, resulting in a delayed response from the Dimmer Module.
Try this:
• Consider if you have removed any INSTEON devices from you network that were part of the slow-to-
respond scene. If so, the links to these devices need to be removed from the controller. Use software to
examine the database of the controller or if you know the modules that were removed, manually remove
their links using the standard unlinking procedure.
• If you are unable to identify the missing devices, perform a factory reset on the controller. This will remove
all links from the controller’s database but will also require that you reconfigure the device’s scenes and
properties.
