I was having issues with the controller not always responding to remote control signal having to hold button until garage door started to move
Now after replacing the two capacitors on the two 5 volt power supply rails
One is used for the up/down limit up/down force circuits
Second one is used for the radio receiver circuit
The main filtering capacitor ESR value was a little higher than a new one

I also have issue with the down force limit circuit is weak but it is very hard to follow on this circuit board right now I have it closing again but the door is much lower than it was I barely go under the door with out hitting my head I going to try to adjust it back up a little higher and see if it starts tripping again
If it does I will buy another controller board from this company and try to repair the one I have
