Hi,
I have been using a 202U V5 wireless relay switch for my 2 garage doors successfully and happily for about 2 years. Last week all remotes stopped working. Trying to reprogram them failed. I had a spare unused 202U V5 so I rewired and replaced the original unit. Reprogramming the remotes still failed. I then checked the power supply and it was 12 volts but I noticed DC Amperage was pulsing. I wasn’t sure if the pulsing was normal so I ordered a new power adapter.
The new power adapter arrived and after I plugged it in I was successfully able to reprogram one of my remotes so that the A button on PRG1 and the B button on PRG2 each opened their associated door. So it seemed I was back to normal operation.
However, when I tried to program a second remote to use in another car something went wrong. I thought I followed the identical programming steps as I did with the first remote but the result was that the A button on the second remote now opened both the door associated with PRG1 as well as the door associated with PRG2.
I tried reprogramming several times with the same odd results.
I tried programming a third remote but had the same odd results.
I also tried setting the transmitter to factory defaults using one of your videos but it made no difference.
The first remote that I programmed still works properly. I’m just stuck trying to properly program any additional remotes.
Any suggestions are appreciated.
Thanks,
Anthony
