Remote works intermittently

I’ve tested the remotes to open, pause, and close my garage door. They work, but for some reason they seem to stop working as soon as I put the cover back on the receiver (202U v6).

The connections look fine - I have triple-checked. I can see and hear the receiver receiving the signal from the remotes. But the door does not open or close every time I use it. I do not have any working theories as to why.

Since you can hear the relay click (every time you pressed remote button I suppose), it means the remote->receiver link is working good.

I would check the receiver to garage door connection, maybe use another relay (#2 instead of #1)?

Other thing worth checking is the power supply, it can cause some weird problems.
