Worn 24-year opener
Twenty-four years on a motor and gearset is a long run, and it shows up as grinding noise, a trolley that slips, or a unit that only responds every third press of the remote. The truck carries belt-drive and chain-drive replacements in 1/2 HP and 3/4 HP, plus the battery backup units that matter here since these homes don't have a second opener on a detached structure to fall back on if the power drops.
