GaryK4 Posted October 20, 2021 Posted October 20, 2021 I have (2) IO Links for my garage doors and they both failed at the same time. I just want concurrence before I toss the in the garbage. I had a spare device and replaced one of the failed devices and it worked fine. Next, I took the failed units to my office and tried to do a factory reset. The manual says it should flash after (3) seconds. My flashed and beeped after (10) seconds. While there seems to be some life in them, I am unable to get then into the link mode! I press the set button for (3) plus seconds and nothing. Is there anything that I am missing? Or is it time to toss them?
larryllix Posted October 20, 2021 Posted October 20, 2021 (edited) As with most other flaky Insteon modules (PLMs, SyncroLincs, and a few others) they likely both have blown power supply capacitors from a powerline surge, that could be replaced. Edited October 20, 2021 by larryllix
Brian H Posted October 20, 2021 Posted October 20, 2021 (edited) You may want to look at the label on the back of the I/OLinc. For the hardware revision. The earlier revisions didn't Factory Reset the same way as the late revisions. The 2450 uses the same LNK354GN Switching Power Supply Chip as the 2413 PLM and V2 Access Points. C7 was the part I found changed. Between hardware revisions. Hardware V1.0 0851: C3 6.8uf/250V C11 100uf/25V C8 10uf/16V C7 10uf/25V 25V rating was close to the 21VDC I measured on it. Hardware V1.8 1202: C3 6.8uf/250V C11 100uf/25V C8 10uf/16V C7 10uf/50V Mounted horizontally over PCB. As it was large to fit the boards hole spacing. Hardware V2.3 1430: C3 6.8uf/250V C11 100uf/25V C8 10uf/16V C7 220uf/50V Mounted horizontally over PCB. As it was large to fit the boards hole spacing. My thoughts are. In V1.8 C7 was changed to 10uf/50V for a better safety margin. In V2.3 C7 was changed to 220uf/50V to beef up the power supply. Edited October 20, 2021 by Brian H Add information 1
GaryK4 Posted October 20, 2021 Author Posted October 20, 2021 Both of mine are: Insteon74551 Rev: 2.3 2214 on the label. I know how to solder, but I am not an electronic component guy. Are you suggesting to try replacing the C7 component? capacitors? If so where do i get it - Amazon? What part number do I search for? I think it is hard to read from the component. I'm retired, so I like projects to augment my golf & tennis ?
Brian H Posted October 21, 2021 Posted October 21, 2021 (edited) 74551 is the Garage Door Kit. Including the I/OLinc, connecting wire and a magnetic sensor. The Insteon I/OLinc is the module you plug into the wall. On the back there should be a sticker. With the part number of 2450 or 2822-292. Looks like Smarthome may have used the kit number on the module label. How it is listed in the Administrative Console. Should show the module part number and the firmware it has in it. The 74551 V2.3 kind of looks like they used the kit number on it and revision 2.3. The module is a power line only module. If you have not tried linking on the same power circuit as the PLM for the ISY99i. You may try that. It is possible C7 is the issue. It should be a low ESR switching supply type capacitor. You have to search an electronic parts suppliers site and look for the specification you want. I would stay away form Amazon or any other site. If they don't show a known good manufactures and it is low ESR. Every manufacturer has their own part number. So unless someone has done it and can supply the number. You have to search. I did buy some for my V1.0 modules. I will see if I can find the part number. It was the 220uF/50V to replace the original 10uF/25V ones Edited October 21, 2021 by Brian H Add information
Brian H Posted October 21, 2021 Posted October 21, 2021 On the V2.3 version. Factory Reset. Unplug for at least 10 seconds. Holding the Set Button power it up. It should start beeping. Keep holding the set Button until it stops beeping. Release the Set button. Shortly it should do a double beep. The module is reset.

Brian, That is what I did. I had a spare device that I set up as well. The spare worked fine. I tried the factory reset in the same outlet on the old one. It did the reset, but will NOT do the link step (double beep) Same procedure, same outlet different results. Edited October 21, 2021 by GaryK4 More info
Brian H Posted October 21, 2021 Posted October 21, 2021 It does sound like it may have a problem. Not clear if the power supply has an issue. It could also be the modules power line receiver or transmitter.
