The complaint we hear most out of Harrodsburg is a chain-drive opener that's started grinding or chattering partway through the cycle - usually a worn gear kit inside an older drive unit, common on openers that have been running since a retrofit install decades back. Second most common: the door reverses for no reason, which is almost always the safety sensors, either knocked out of alignment or just aged out.
We also see openers that flat-out struggle to lift the door - straining, slow travel, or stalling partway. On a house built around 1971 with the original wood or early steel door, that's often a mismatch between opener horsepower and the door's actual weight, not a bad opener. The climate here runs cold and swings enough through the year that grease inside an old drive unit thickens up in winter, which can look like a dying motor when it's really just old lubricant.
If your opener is quiet and lifting fine but the remote range has gotten short, that's usually the receiver antenna or a weak battery, not the motor - an easy fix, and one we'd tell you not to pay for a full opener swap over.
