We start by testing the opener's force settings and running the door through a manual cycle to see whether the door itself is the problem before we open the motor housing. If it is the opener, we check the drive gear, the capacitor, and the logic board in that order, since that's the sequence that actually fails on these older units.
For openers original to 1970s-era houses, we'll often recommend a straight swap rather than a gear replacement, because a 45-year-old motor winding isn't something we can warranty with any confidence. For newer units, repair is usually the right call. We travel out from Eau Claire for this work, about 8 miles to Seymour, so we schedule the full diagnosis and repair in one visit rather than a separate estimate trip.
