For a few days there was a grinding sound whenever the door started moving. Now the motor spins freely and the door stays exactly where it is.
What you get from the visit is more than a working door. You get told, in plain words, what was wrong and why it happened: a gear that had run dry for years, a sensor knocked out of line by a snow shovel, a wall control left in lock mode by a visiting grandchild. Small repairs are done on the spot, settings are recorded, and the door is demonstrated on every control you own. You also learn the short monthly test that catches most opener problems before they strand a car, so the next fault is one you notice while it is still small.

Garage Door Opener Diagnosis and Repair · West Grey
Scene 1
Behind the cover of the head unit and along the rail sits the drive train: motor, capacitor on AC models, drive gear, sprocket, and then the chain, belt or screw that moves the trolley. The technician listens first, because sounds are specific. A hum with no motion suggests a capacitor or a stripped gear; a motor that runs while the trolley slides alone points to a disengaged carriage or a broken drive; a grinding start followed by silence is a worn gear finishing its life. Then the parts are inspected directly: gear teeth, sprocket, chain tension, belt condition, trolley wear, and the coupling between rail and head.
Scene 2
When the by-hand check shows the door is heavy, drifting or binding, the work order changes. The opener is left disconnected and the door side is corrected first: worn rollers replaced, dry hinges and rollers lubricated, loose track brackets tightened, a dropped header bracket re-secured, and spring or cable faults handed to the tensioned-hardware work they require. Only when the door lifts and holds by hand is the trolley re-engaged and the opener tested again. Very often the opener that seemed faulty runs perfectly once it is moving a balanced door, and the repair becomes lighter and longer-lived than any change made at the motor.
Scene 3
The red cord hanging from the rail is the emergency release, and you now know how to use it properly. Pull it only when the door is closed, so a door that turns out to be unbalanced has nowhere to fall. The door then lifts by hand, useful during an outage. To reconnect, most units re-latch when the opener is run and the trolley meets the carriage, or when the door is lifted until it clicks. The handle should hang no higher than about 1.8 metres and clear of the car. If the door feels heavy when released, that is a spring message, not a test of strength.
What shapes the quoteSaugeen Door Specialists
FeesSame any hour
Rollers, hinges, bearings and springs benefit from a garage door lubricant once or twice a year. The chain, belt or screw-drive rail is a separate question, since each drive type calls for its own product and schedule from the opener's manual rather than one rule for every unit. The track itself should stay clean and dry, because lubricant there collects grit and makes rollers slide instead of turning. The technician can point out the spots on your door at the end of the visit.
By separating them. With the door closed, the emergency release is pulled so the opener is out of the picture, and the door is lifted by hand. A balanced door rises without strain, hangs where you leave it around waist height and stays open at the top. If it does, the opener is at fault. If it is heavy, drifts or binds, the door is the cause and the opener was only reporting the strain. This one check prevents a great many wrong repairs.
Not usually. Outages and the surges that ride along with them commonly trip a breaker or a ground-fault receptacle, blow the small fuse on the board, or knock out the transformer, and each of those is a modest repair. A surge that damages the logic board itself is the more serious case, and whether that board is replaced or the unit retired depends on the model's age and part availability. The diagnosis tells you which case you have.
