2412S is not Dual Band so it has no Insteon RF receiver in it. To receive the Motion Sensors or Hidden Door Sensors RF signals. So another Dual Band Module maybe receiving it but the power line signals are not getting back to the 2412S. If you have no Access Points, Range Extenders or a Dual Band devices. No Insteon RF communications will happen. Since you have a 2412S PLM. Are you using an ISY99i or ISY994i? Due to firmware storage limitations in the ISY99i. The latest firmware that supports the newest Insteon Devices can't be loaded into it. So the latest Insteon Modules will not work correctly with an ISY99i. The upgrade from a ISY99i to ISY994i offer is still showing on the UDI direct sales page.

If the KPL has a sounder in it. Maybe the flaky power supply was making it pulse and click.

Your photos didn't show the power supply IC. The LNK354 switching power supply IC was used in many of the Insteon modules. Including the 2413S/U PLM. If your module used that IC. The capacitors you use should be of a Low ESR type. If not they will fail in a much shorter time than a low ESR one will.

I have seen a test of an inexpensive cell phone charger. That put so much garbage on the power line at close to both the X10 and the Insteon power line frequency http://jvde.us/x10/x10_cellet_noise.pdf

I would suspect the electrolytic capacitors. In the 2413S PLM. The caps where bad but showed no signs of bulging or spilling out their guts. I don't have a capacitor or RSR meter to test them. The green one second from the left is one of the brands in the PLMs. I can't read the brand of the other ones.

The silver cylinder glued to the PCB looks like a crystal for the processors oscillator.

The I/OLinc Sensor Input is for dry contacts only as it has its own pull up to +5 volts. Yes the LED is on the sensor Input and can glow even if the Sensor Input is not below the threshold of about <.95 volts.

The 120 volt AC relays should work. You mentioned stopping part way. The open closed micro module will not to that as Stu pointed out. It has a preset time activation you set during the calibration part of the installation.

Does the dryer have electronic controls? My thoughts are its electronic controls is generating power line noise or the manufacturer put an AC rated capacitor directly across its power feed and it is a signal sucker. Was the filter designed for X10 or Insteon signals? Some generic filters will actually kill the X10 or Insteon power line signals as noise. Finding an X10 or Insteon power line filter with a high enough current rating could be a problem. Opening the dryer and just filtering the electronics should work but would void any warranty and maybe have a poor spouse acceptance.

Smartenit makes some plug in Insteon Modules with more than one relay. That could be used to switch Dry Contact Inputs. EZIO40 is one that comes to mind. They are plug in and not wired where you can hide them in an electrical box. I also don't know if all there features are completely handled by the iSY994i. I know that some features need you to use their Utility Suite to be set from default.

Transformers can also have a higher output voltage. If not loaded close to its rated current.

You have to power up the new PLM before the ISY994i. The ISY994i checks for a PLM and its ID when booting up. If it doesn't know the new PLMs ID. It may try and use the incorrect ID from the old PLM.

Thank you for the information on the Dual Band On/Off module.

The 2456S3 Appliancelincs also have the Local Control Sensing current. The Revision 4.? ones also have a snubber network across the relay contacts. So when Off there is current through the snubber also. So small load LEDs may also glow with them. I can't say about the Dual Band On/Off Model as I have none to test.

Measures the current being drawn on the AC power line by the device connected to it. Then send an on or off depending on the change in current drawn by the device connected to it. http://www.smarthome.com/synchrolinc-insteon-2423a5-power-synching-controller.html

Turning Off the Load Sensing feature does not remove the sensing current. It just tells the module to ignore seeing the local loads on off switch being toggled. As mentioned a small incandescent load like a 4 watt night light. Should stop the the low glowing of the LEDs.

The external sensor is only displayed on its LCD screen and not reported at all. There is a thread here where the user. Disconnected the internal sensor and tied the external one to the solder pads the internal one was connected to. http://forum.universal-devices.com/topic/9152-how-to-monitor-water-temp-via-isy-and-catch-more-fish/

The Red Labels on modules indicate it is a Controller and Responder. A Blue Label on a module is a Responder only. If you click on the module in question. On the right side of the display. It will show what it is controlling and what it responds to. On responders only. It will only show the devices it responds to.

Looking at the wiring instructions. One thing you may have missed. The supplied transformer is made to be mounted in a knockout hole. On an electrical box . So you would have to splice a power cord onto the wire pigtails. If you want to plug it into an outlet.

The output of the transformer could be higher than 24 volts. If it is lightly loaded.

If you had problem with formatting the SD card. You may have an SD card that is marginal.

If you did not do anything to scenes or modules. After changing the PLM. Use the PLM replacement instructions in the links provided. If you made some changes. Some links you added with the new PLM not detected may have improper links in them. Though most should still be OK.

Open the Event Viewer and use level 3. Try and add the problem 2475DA1. Save the Event Viewer information and post it here for examination. The latest firmware lets you save to the Clipboard or you can save it as a .txt file. You are using the latest released firmware 4.2.18?

I got an early Icon On/Off module. The label on the micro said Beta. I was told that the firmware in it was a released version and the labels had not been reprinted removing the Beta designation.

The Icon product line was a less feature and cost. One year warranty modules. No pass through AC outlet on the front cover of plug in modules. Made by the same factory who also make the full featured Insteon line. When the seven year extended warranty could be added to the Insteon line {now no longer an option}. The Icon was not sold with an optional seven year warranty.
