The motor runs, the chain rattles along the rail, and the door does not move a millimetre. You notice the little carriage sliding back and forth on its own.
Every diagnosis ends with the same two tests, because an opener that moves the door is only half fixed. First, a length of 2x4 is laid flat on the floor under the centre of the door and the door is closed onto it; it must reverse on contact and return to fully open. Second, with the door closing, an object is passed through the photo-eye beam near the floor; the door must stop and reverse. These tests are how the opener standard defines a working unit, and they are how the technician proves that the fault found was the fault fixed.

Scene 1
Each way of telling the door to move is tried on its own: the wall control, every remote, the outside keypad and, if fitted, the phone app. The pattern of what works tells a story. If the wall button works and nothing wireless does, the receiver, the remote batteries or a lock setting is suspect. If a remote works only up close, range and interference are the topic. If nothing at all works but the unit's light responds, the fault is downstream of the controls. The technician also checks the wall control's own indicator, which on most models blinks continuously when lock mode has been switched on by accident.
Scene 2
On an AC opener that hums and clicks but never turns, the start capacitor is the first suspect. It is discharged, tested and replaced with one of the same rating, a routine job that returns a dead-sounding opener to normal in many cases. If the motor still fails to turn with a good capacitor, the technician checks for a seized shaft, burnt windings or a failed thermal cut-out, and confirms the motor is not simply being stalled by a locked or bound door. A motor replacement is weighed against the age of the unit and the availability of the part, and that judgement is explained before any decision.
Scene 3
When the diagnosis finds an opener that is safe today but not for long, you leave with a plan rather than a surprise. You know which part is wearing, what the warning signs will be, and how the decision to replace is likely to present itself. If the unit is one the industry recommends replacing, such as a head unit with no photo eyes, that is set out plainly along with what a modern belt or direct-drive unit changes: quieter running, battery backup, soft start and stop, and sensors that meet the current standard. The door is left working and safe while you decide.
What shapes the quoteInnisfil Garage Door Co.
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.
Two usual reasons. The travel limit is set a fraction too long, so the door reaches the slab, meets it harder than expected and interprets that as an obstruction. Or the bottom seal has stiffened or frozen and the last few centimetres take more force than the setting allows. Both are adjusted after the door is checked for balance, and the fix is confirmed by closing the door several times and running the contact reversal test.
Look for the simple things: is the opener plugged in and its light working, has the wall control's lock indicator started blinking, does another remote work, is anything sitting in the path of the sensors, and are the little sensor lights steady. Note what the motor does when you press a button. Do not try to lift a door that is stuck if a spring looks broken. Whatever you find, tell the technician; it shortens the diagnosis.
