A few things are worth checking before you call anyone. If the opener runs but the door won't close, check the safety sensors first - two small eyes near the floor on each track, usually with a small LED. If either light is off, flickering, or the two aren't aimed at each other, that's your problem, and it's a five-minute fix with no tools beyond your hands.
If the opener hums but the door doesn't move, do not keep hitting the button. Repeated attempts on a jammed gear or a failing capacitor usually finish off the motor, turning a $100 repair into a $300 one. Pull the manual release, move the door by hand, and leave the opener alone until someone looks at it.
What we don't recommend DIY: opening the opener housing to test the circuit board, or replacing a logic board yourself. The boards look standardized but aren't always compatible across model years, and a board ordered wrong doesn't get refunded easily. That's the one place where a phone call before you buy parts saves real money.
