I have a Sears chain-driven garage-door opener that's about ten years old.
It's in excellent mechanical condition but lately it's very slow to begin
or closing cycle. I find myself having to push the remote button for 8-10
seconds at times
before anything happens.
The batteries are newly replaced, I've tried repositioning the pickup
so far nothing seems to help.
What am I missing here???
I would do what you are doing, rule out reception. I would try and
stand inside the garage and test the remote. Ifa difference is
noticed, then it might be reception. Also, I would take a look at
everything, rollers, chain, supports. Ask myself, "does anything
Post a followup.

If you push the hard-wired button on the wall, does it open immediately?
If so, then the problem is related to the receiver/transmitter. Perhaps your
transmitter button is worn out. Try cleaning the switch or use a spare
I'll second that approach. We have Craftsman units which are about 20
years old now and still going strong, and the transmitters (and the
receiver too I suppose) use slug tuned coils which set the RF operating
I recall having to tweak the slug in one of the transmitters to get it
to operate as far from the garage as our other units.
I drilled a 1/8" hole in the case so I could reach the slug with a
tuning tool left over from the old vacuum toob TV set days and adjusted
the slug by trial and error tweaking as I moved away from the garage.
Worked for me...
