I have a 202U v6. It was working. Does each channel only accept a single remote? I though I had it working with both remotes, but then it stopped working and I can’t get it to learn the remotes again.
Just to be clear, It was working properly. But now the power LED is on, and if I press a program button the signal LED comes on, but it no longer blinks three times.
Each receiver accepts up to 510 transmitters.
Would you please check if battery in remote needs to be replaced?
If still doesn’t work, might be the receiver module went defective.
Make sure you turn off all the LED light bulbs inside your garage AND the opener. LED’s are quite ‘noisy’ which will block your transmitter signal. There are opener specific LED lights available
