Sluggish Garage-door Opener



Question:
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 the opening 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 antenna, but so far nothing seems to help. What am I missing here???

Answer:
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 frequency. 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...
