restoring old garage door opener-receiver/transmitter

[noquacks]

Exactly Why? A valiant effort I will admit. a fancy way of shotgunning especially given the difficulties of not being there to take the measurements.
The help given to you is top-notch but it simply cannot be ruled out that nothing was wrong with it in the first place but I do admit it is a good feeling to stand on the shoulder of giants.The end result is clear & successful.

Right. It is working now, so lucky for me, lets see what happens in 4 years from now....LOL.

Agreed is a wonderful thread, great read, packed full of information. Enjoy

If removing the cover and then suddenly it works, I would suspect a loose or dry/cracked solder joint somewhere.
The simple movement may have released a slight flex in the mounting position.
Certainly NOT definitive but certainly worth a look if it plays up or stops working again.

I have worked with other folks (not this crew!) who believed that intermittent problems, like this one appears to be, were simply resolved by hitting the object in question with a bigger hammer. Hmmm. If simple visual inspection fixed the problem, we may have a quantum mechanical situation caused by your collapsing of some retarded wave function... or some such shit.

Update: People, 2 problems with this system now. 1st, door does not respond to transmitter clickers, have 2, both batteries checked out as being above 3V. Could it be the receiver? How would one start checking for the fault?

2nd, not as big a problem, just a quirk, whenever the temp is below 60 deg F, the motor for the system does not respond immediately. It moans and groans for say, 20 seconds, then the garage door finally opens as the chain starts to move/pull. Yes, when it warms up as it is starting now, and temp is above around 60 F the motor works immediately. Is it starting to go, after about 40 years? Things dont last as long they used to......LOL

Thanks, people.

Your question has already been answered here, in a timely manner.
So what is the word or expression for useless advice?

whenever the temp is below 60 deg F, the motor for the system does not respond immediately.

Replace the lubricant(s) in motor and gear with fresh ones. The old lubricants may have become too viscuous over time.

So helpful, Harald! Good tip, I didnt know. Any advice on why the remote doesnt trigger the receiver?

Any advice on why the remote doesnt trigger the receiver?

So many possibilities, hard to diagnose remotely. See post #43. If this doesn't turn up an issue, you'll have to dig deeper into the circuit.
Do you have a second transmitter to verify it is the receiver that has the issue, not the transmitter?

yes, in my post #45 I mentioned that I tried 2 transmitters. Both were working a while ago before this started. I first thought it has to be bad batteries, but they checked out as being >3 V. I will try messing around more, with those transmitters.

Hello,

How is the receiver powered?
It could be that the capacitor of the powersupply dried out.
This would lead to an instable powersupply.
Is there any change at the receiver?

Question . . . . . . . .As Per . . .
Any advice on why the remote doesn't trigger the receiver?
I gave you the original schematic . . . . . . . . . now you have repurposed a complete different receiver to that board. So,now tell us what voltage level from the original power supply circuitry is now powering the new receiver.
Also, the new receiver unit is having a SPST relay which should connect into the garage door lift/lower motor mechanism . . . . . .is there also a possibility that there is being a supplemental LED indicator used in that receiver that lights on detecting a received transmit signal ?. Thus that would confirm acknowledgement of confirmation of an incoming transmit signal.

I don't see that there is enough, or any info on that added receive board . . . . . . .any chance that its design complement includes the use of an 8 pin LM358 I-eye C-see ?
Thaaaaassssit.

Update: Sorry for the delay, people, but finally got around to doing some checks. The receiver mounted at the top (near the door motor) is plugged into a 120V plug, and it does read 120V, so power is available. next, I noticed that upon touching the adapter for the receiver , which is plugged into that 120V receptacle the black box/adapter is not warm to the touch. Is that normal? Could that be the culprit?

If this helps, the receiver is a "Solidremote" Brand, model 202U v5.

Thanks, people.

 

[Harald Kapp]

he black box/adapter is not warm to the touch. Is that normal?

Modern power adapters are very efficient (or should be) and do not get warm unless the load is very high. Which it should not be in your case. One way to find out whether the adapter works is by checking the output voltage under load.

 

[noquacks]

I opened up the cover to the receiver and the LED red light is on. I dont understand the "under load" idea as if the garage door motor does not receive the signal how can it activate to turn on and be in "under load"?

This is the picture of the receiver: (oops, not working. attach picture, and savem nothing shows up......)

 

[noquacks]

Turns out the batteries must have been bad even at about 3V. Replaced with better (3.2V) and I got one remote to work with reprogramming! So happy! But somehow, the 2nd remote does not want to program at all. Ordered new pack of 3V batteries, arriving tomorrow. Question: on this type of receiver, if I programmed the 1st remote to pin #1, to correspond to #one of 4 buttons on remote, can I repeat the same with remote #2, with pin#1 on receiver, and same #1 on 2nd remote? Or must I program it to #2 on 2nd remote?

Thanks.

 

[noquacks]

Waiting for new batteries. 3+V may not be enough, need more like 3.2 or so........

 

[noquacks]

new 3.2V battery did the trick. All the fuss for a bad battery. Anyway, thanks for the help, people.
