Reefrus Posted November 30, 2018 Share Posted November 30, 2018 I have one channel on one of my controllers that has quit working. What do I need to check other than it has no power coming from it. All other channels on the controller are working. Link to comment Share on other sites More sharing options...

Some have Fuses per port, some have fuses per BANK. Being an old school ET, I look (and smell) for scorched parts. Link to comment Share on other sites More sharing options...
Reefrus Posted November 30, 2018 Author Share Posted November 30, 2018 It is a CTB16PCG2 - U4. Not for sure what the U4 means. It has 2 fuses one for each set of 8 channels. All channels work with exception of channel 10. do not see or smell any scorched or hot spots, that channel was not over loaded. I checked output voltage and zero on that channel but all other channels the voltage is good. Link to comment Share on other sites More sharing options...

That channel will be down for this season unless you soldering skills allow you to change out that part. Link to comment Share on other sites More sharing options...
Reefrus Posted November 30, 2018 Author Share Posted November 30, 2018 I suspected TRIC was not for sure, I moved everything from that channel to a spare channel. Where can I get Triac from LOR. I can solder but will I will wait until end of season to repair. Thanks Link to comment Share on other sites More sharing options...

As I understand it, they will generally just send you a few for those of use that can solder. Links have also been posted in the forum for devices from several of the on-line electronics parts houses. Link to comment Share on other sites More sharing options...

Orville Posted December 1, 2018 Share Posted December 1, 2018 (edited) Just make sure you tell them EXACTLY which model/version CTB16PC you have, not all use the same triac! Edited December 1, 2018 by Orville Link to comment Share on other sites More sharing options...
