I have been having issues with this garage door opener for a while first the range of the remote was a lot less and sometimes it would start to go down and stop for no reason that I could find and would every once in awhile to start with then it started going more frequently until last Saturday when I opened the garage door it refused to close so I cranked up force all the way maximum limit this did not work also the sensor on one side that has a green and red lights that are supposed to be on when the door is open and there are no obstacles in the way on the original board the only light that...

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 have vintage Slavedor garage door opener that has stopped closing the door. If I disable the up/down current control to the motor it works fine. I've attached the larger control board which is for everything and the smaller current control board.
Normally the current control is set slightly above the maximum current normally used. If the door exceeds this it should stop and reverse when closing or just stop when opening. Can someone please explain how the current control board works so that I can try and repair or replace the defective parts.
I see my self as an interested novice...

I'm trying to guess what component got burnt on the control board for my Nice garage door motor Nice SNA4/A. You can see it in front of the 2 capacitors. The component is connected across the 36V rectified input wires, maybe it was some kind of protection device?
All the pictures I could find were of the whole product, so enclosed in the plastic box, eg. https://www.ebay.co.uk/itm/123998876212
Any help appreciated.

Hello everyone,

I'm turning to the Badcaps community to help me troubleshoot the radio Rx card from my (old) garage door opener. While I could just ditch that card and replace the whole system, I first would like to understand "why" it suddenly stopped working, because that's just how I am wired...!

Some basics: the receiver works on a 30.875 Mhz frequency. Yes, I'm aware this is not in use anymore in a looot of places. It does not use any rolling code, it's just a regular dip-switch code that you have to set up on both the receiver and transmitter. The receiver...
