I'm new here and couldn't find an option right off to post a new question concerning an RF20 remote, so I'm just addressing the thread. I bought one of these (plus RF box) about 15 months ago. It's been working fine. A day or two ago I wanted it to learn a code from another remote and to assign it to a new key. I went through the motions, and it ended up with 'READY' showing on the display, which means it's good to go for learning. But when I held the other remote to the IR window on top and pressed the button... nothing happened. It didn't say 'GOOD'; it didn't say 'FAILED.' It didn't do anything at all.
I backed out of the key-learn mode and started over, used a different remote as a source to learn from. Same results; says 'READY' but won't do anything. I tried various other things, including a new set of batteries. Nothing made any difference -- it still won't do anything when I have it ready to learn a new key.
I'm at a loss. It functions perfectly otherwise; all previously-learned keys etc. work fine. I just can't get it to learn any new keys. I remember adding a few new keys some weeks ago, and it worked fine then.
It's about 3 months out of warranty, so I'm bracing to buy a new RF20 to replace it. But I thought I'd ask first if anyone else has experienced this sort of problem with this remote. Any relevant info would be appreciated. Thanks!
