It is a January morning and the door lifts about a hand's width, groans, and settles back down. When you pull the release and try by hand the door feels far heavier than it used to, and the bottom seal is stuck hard to the slab.
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
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
You leave knowing a short check that catches most opener trouble early. Once a month, with the door open, lay a piece of 2x4 flat on the floor under the middle of the door and press close; the door should touch it and go straight back up. Then close the door again and pass a broom handle through the sensor beam near the floor; the door should stop and reverse. Watch the sensor lights stay steady. If either test fails, stop using the opener and book a visit. These are the same tests the technician just performed, and they are all the standard asks of a working unit.

Through the house if the garage connects to it, or through a side door. Many doors also have an outside keyed emergency release, a small keyed cylinder that pulls the trolley free so the door lifts by hand from outside. If yours does not have one, the technician can fit a keyed release kit as part of the visit so there is a safe way in next time; until then, an alternate entrance is used and the diagnosis proceeds once inside.
The list is short and familiar: the drive gear and sprocket on chain-drive units, the start capacitor on AC motors, the photo-eye pair and its wire, the trolley and carriage, the wall control, the remotes and their batteries, the light socket, and on newer units the battery backup pack. Logic boards and motors are replaced less often and weighed against the unit's age. Most of the common items are carried to 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.
