Re: Garage Door Opener has Badcaps!

Re: Garage Door Opener has Badcaps!
Reel to reel tape recorder, one of my friend (TV shop owner) collects and repairs them, He wants me listen to the recorded tape which is like 4-6 hours, I said stereo VCR is better quality than that which looks like old Mini computer tape memory storage unit. I did not know has motor capacitor. (for start or run?)
PS: As I remember is Akai. He collect old GE fan (He uses them in the shop) and antique Cathedral and Table top Radio. New his shop is mainly to restore old tube radio ( he changes $250-$480 to fix one!) and round CRT TV.
PS: He shows me the vacuum tube caddy. He has more junks than me.....He is my TV repair teacher...........................

Re: Garage Door Opener has Badcaps!
a high-voltage metallised paper (MP) capacitor of value 2 uF (for 50 Hz line frequency), and 1.5 uF (for 60 Hz line frequency). Just 10Hz difference from 2uf to 1.5uf is a lots?Comment

Re: Garage Door Opener has Badcaps!
50Hz to 60Hz is 20% change so for the Xc to remain the same the Capacitance is changed by about 20% so 2uF is changed to 1.5uF (1.6uF to be exact)Never stop learning

And the MP Capacitor size is huge.Comment

Re: Garage Door Opener has Badcaps!
Are you sure it is Metalized Paper? I do not think so.
More likely to be Metalized Polypropylene which is the type commonly used for motor.

I had a lot of trouble with the WiFi connection from my router inside of the house into a ( new ) metal garage I had to run a 150 ft cat6 patch cord so the WIFI connection would be strong enough for the WiFi connection on the garage door opener would work correctly ( my son has a work out area in the garage as well and he was having to put his phone near the door to be able to stream music ) ( so I was going to eventually put WiFi out there anyway )
This garage door opener WiFi is very touchy if you lose the power it does not remember the password for the router which is weird or... -
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... -
Hi,
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.
